Writing a literature review for a research paper is an important stage in the academic research process. It entails doing a critical review of existing literature to provide a comprehensive overview of current knowledge on a certain issue. In this article, we will walk you through the important processes for writing an excellent literature review. We’ll discuss how to discover relevant literature, combine findings, and arrange your review to provide clear insights. Whether you’re a seasoned researcher or a first-time writer, this guide will give you essential advice and tactics for improving the quality and impact of your literature reviews.

What Is a Literature Review?

A literature review is a survey of key scholarly sources to do with a particular topic. It lists a number of important and relevant pieces of writing and, in doing so, gives the reader a summary of the topic’s current knowledge and debates. When writing a literature review, a student should do more than just summarise each individual source. They should analyze them closely and compare them with one another.

A key part of academic writing involves understanding what has been said and debated about the chosen topic. Once a student has done their research, they’re in a better place to write their research paper and put their point across. A good literature review should let the reader know what the salient points from the student’s research are.

What Is the Purpose of a Literature Review?

The purpose of a literature review is to show the reader what research has been carried out on the chosen topic in the past. When writing one, you’re aiming to bring the reader up to speed with other people’s research before sharing your own findings. You should summarise where the topic’s at right now before building on it with your research.

Another important purpose is to give more weight to a student’s key arguments. By listing and comparing some of the key sources, a student can give context to the main points in their research paper; they can even fill any gaps in certain areas that others haven’t yet managed to fill.

If you want to know how to write a literature review in a research paper, carry on reading. We’ll run you through the process of putting one together, and we’ll talk about some of the different approaches you can take in writing one.

Steps in the Literature Review Process

A literature review can make a Ph.D. dissertation, or any other kind of  research paper more convincing. For a review to be effective, it should be detailed and have substance but without overdoing it; in other words, it should be concise.

If you’re not sure how to write a literature review for a research paper, we’ll show you how in this section. Here are the main steps to take:

• Decide on your topic Your topic is the base on which you build your research. It also determines what research you carry out.
• Search for sources to include The sources you look at for your research paper should be authoritative and relevant. They should be scholarly in nature, though not all of them will be.
• Determine which ones are the most useful Look through your sources and think about how much each one adds to both the topic you’re exploring and the research you’re carrying out. Including all sources isn’t practical, so only choose the most appropriate and fitting ones.
• Identify where the research is currently at By reading other people’s research, you can get an idea of what the current thoughts and debates relating to your chosen topic area.
• Come up with a structure Literature reviews have quite simple structures. More information on these is given below. Think about how you want to present yours and how you’re going to arrange your findings.
• Write your literature review A well-written literature review gives the reader all the necessary information about each of the sources. It clearly explains how the sources are connected and what they contribute to the chosen topic.

It’s a good idea to come up with headings and subheadings and go from there. These are both important, and we’ll talk about them in more detail later on. During the planning process, they can help you come up with a definitive structure for your literature review and consolidate your thoughts.

You may want to pay someone to write a literature review for you. Many people who are struggling with literature reviews do this. They don’t hand in the work that someone else has done for them. Instead, they read through the other person’s work to get ideas and inspiration. Doing this can help people write their own literature review much more effectively.

How to Structure a Literature Review

For this section, we’ll look at how to write a literature review. We’ll focus on the different approaches you can take according to the type of research you’re doing and how you wish to present it.

Chronological

Listing your sources in chronological order is perhaps the simplest approach to take. However, make sure you don’t just list the sources and summarise them. You should still try to establish some sort of connection between them. Highlight movements, patterns, and new ideas. Show the reader how scholarship on the topic has changed over time. You could even organize your sources into broad historical periods and have these as subheadings in the literature review, for example.

When writing a thematic literature review , you should organize your sources by theme. You should consider this approach if you’ve found multiple themes during your research. Create literature review subheadings for each theme that stands out to you. If you go for a thematic style, think about what your RRL subtopics are and what themes you would use to organize them.

Methodological

A methodological literature review is one whose sources involve the use of different research methods . You could have one source that’s numerical and involves graphs and statistics, for example, and another that’s entirely made up of written text. The subheadings in a literature review that’s methodological could focus on different types of research, focusing not so much on what has been researched but how it’s been researched. As a literature review subheadings example, you could therefore have one subheading for literary sources, another for numerical/graph-based data, and so on.

Theoretical

With a theoretical approach, the focus is on the body of theories relating to the topic that’s being discussed. The aim is to determine what theories there currently are, how they relate to one another, and how much they’ve been looked into.

These are just some of the different ways you can go about writing a literature review. The approach you take will depend on the nature of your review and the topic you’re looking at.

Writing a literature review can be an intimidating task to tackle, especially if you are not familiar with the literature in the field. Fortunately, there is a  paper writing service online that can help you create an outstanding literature review in no time. Our service is helpful for students, researchers, and others who need to compile a comprehensive and informative literature review.

Literature Review Outline

Writing a good outline for a literature review is important for your research paper. It helps you organize your thoughts and ideas and gives you a clear direction for the writing process.

An outline is not a formal document but rather an informal guide to assist you in organizing the information you want to include in your paper. The outline should be written in paragraph form, with each paragraph representing one major idea that will be expanded upon in subsequent paragraphs of the paper.

The main purpose of writing an outline is so that you can organize all of your sources in a way that will help you write a clear, concise essay. You just want to throw together quotes and facts without any order or reason. This will make it hard for the reader to follow along with what you are saying and make it appear that you have no idea what you’re talking about. This can result in a low grade for your paper and make it difficult for them to understand what is happening within the text.

• Introduction The introduction should include a brief summary of the literature that is being reviewed, including the general topic and your specific focus. You should also provide some background information on the topic to help the reader understand why it is important. You should not include any citations in this section, because you will do that later in the paper.
• Body The body is where you provide an overview of all the sources or literature, you have used for your paper. You should include an introduction to each source and a brief summary of what was found in each source. In addition to providing summaries, you should also describe how each source relates to your research question or hypothesis and then relate them back to each other if they are similar enough to be compared. Finally, you should explain how each source relates to one another in addition to explaining how they relate to your research question or hypothesis.
• Conclusion The conclusion should summarize your arguments throughout the paper and then tie all of these things together into one coherent argument that proves or disproves your hypothesis or research question in relation to other sources discussed throughout this paper (and/or).

Writing a literature review is an integral part of a successful research article or dissertation, as it helps to synthesize and connect the existing body of knowledge. To write your lit review relevantly, it is important to ensure that you include new information when constructing your review and connect existing ideas and themes. A useful literature review outline can provide a structure for expressing your views, allowing you to connect and organize your ideas consistently and effectively.

Literature Review: Writing Tips

When writing a literature review, it’s important to include all of the information your assignment requires. Sometimes, instructors will give you specific guidelines for how long your literature review should be and how many sources it needs to include. If they don’t, however, you’ll need to decide what works best for your situation.

A literature review outline will be the foundation of your paper. It will tell you what information is important and how to write it cohesively and logically. When writing, it’s important to only include facts backed up by evidence. This means that if you are writing about any research topic, there must be at least one piece of published work that backs up each claim or opinion you present.

If there isn’t a source supporting your writing, don’t put it in because it makes your paper seem like speculation or opinion rather than fact-based knowledge about the issue at hand. Another tip for writers is to write clearly and concisely so that readers can understand what they are reading quickly without having any difficulty following along from one point to another throughout the entire essay (or book).

Readers may get bored very quickly if they feel like they have to struggle through something too much before getting into where things go next. Therefore, proper grammar usage should also be kept while doing this type as well, so there are no mistakes left behind after editing later down the line during the publishing stage itself.

The following are the most important tips for writing a literature review:

• Make sure that each paragraph covers a single subject or idea.
• Start with a thesis statement, which should sum up the paper’s main idea in one sentence.
• Write each paragraph in a way that flows from one point to another logically and coherently.
• Include quotes and paraphrases from sources you have read in order to support your arguments and conclusions.
• Make sure that you use credible sources as evidence for your claims and arguments in your paper.

As well as learning how to write a literature review for a research paper, you’ll learn to be more productive and use your time more wisely. Writing services help you put together literature reviews more efficiently. They give you the opportunity to work with an experienced writer who can offer tips in writing RRL, help you with literature review formatting, and more. For example, you can even get things like literature review headings and subheadings so you can see how best to write your headings.

Remember that while the literature review isn’t the main part of a research assignment, it’s still significant. It’s important that you write it as best you can so that your research has more backing and will be taken more seriously.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

Structure of a Literature Review – Outline

When you write a literature review outline, you are laying the foundations of great work. Many people rush this part and struggle later on. Take your time and slowly draft the outline for a literature review.

The structure of a literature review consists of five main components:

• Introduction: Provide a brief overview of the chapter, along with the topic and research aims to set the context for the reader.
• Foundation of Theory or Theoretical Framework: Present and discuss the key theories, concepts, and models related to your research topic. Explain how they apply to your study and their significance.
• Empirical Research: Review and analyze relevant empirical related to your research question. Highlight their findings, methodologies, and any limitations they possess.
• Research Gap: Identify any gaps, inconsistencies, or ambiguities in the existing literature. This will help establish the need for your research and justify its relevance.
• Conclusion: Summarize the main findings from the literature review, emphasizing the importance of your research question and the identified research gap. Suggest potential avenues for future research in the field.

Sentence starters for each section of your literature review:

Literature review examples and types.

Based on the typology of literature reviews from Paré et al. (2015), the following list outlines various types of literature reviews and examples of when you’d use each type:

1. Conceptual Review: Analyzes and synthesizes the theoretical and conceptual aspects of a topic. It focuses on understanding key concepts, models, and theories.

Example use: When aiming to clarify the conceptual foundations and explore existing theories in a field, such as investigating the dimensions of job satisfaction.

2. Methodological Review: Evaluates and synthesizes the research approaches, methods, and techniques used in existing literature. It aims to identify methodological strengths and weaknesses in a research area.

Example use: When assessing data collection methods for researching user experiences with a new software application.

3. Descriptive Review: Provides a broad overview of studies in a research area. It aims to describe the existing literature on a topic and document its evolution over time.

Example use: When investigating the history of research on employee motivation and documenting its progress over the years.

4. Integrative Review: Combines and synthesizes findings from different studies to produce a comprehensive understanding of a research topic. It may identify trends, patterns, or common themes among various studies.

Example use: When exploring the links between work-life balance and job satisfaction, aggregating evidence from multiple studies to develop a comprehensive understanding.

5. Theory-driven Review: Examines a research topic through the lens of a specific theoretical framework. It focuses on understanding how the chosen theory explains or predicts phenomena in the literature.

Example use: When studying the impact of leadership styles on team performance, specifically using the transformational leadership theory as a basis for the analysis.

6. Evidence-driven Review: Aims to determine the effectiveness of interventions or practices based on the available research evidence. It can inform the decision-making process in practice or policy by providing evidence-based recommendations.

Example use: When assessing the effectiveness of telemedicine interventions for managing chronic disease outcomes, providing recommendations for healthcare providers and policymakers.

By understanding these types of literature reviews and their appropriate usage, researchers can choose the most suitable approach for their research question and contribute valuable insights to their field.

How to Write a Good Literature Review

To write a good literature review, follow these six steps to help you create relevant and actionable content for a young researcher.

1. Define the review’s purpose: Before starting, establish a clear understanding of your research question or hypothesis. This helps focus the review and prevents unnecessary information from being included.

2. Set inclusion and exclusion criteria: Use predefined criteria for including or excluding sources in your review. Establish these criteria based on aspects such as publication date, language, type of study, and subject relevance. This ensures your review remains focused and meets your objectives.

3. Search for relevant literature: Conduct a comprehensive search for literature relevant to your research question. Use databases, online catalogs, and search engines that focus on academic literature, such as Google Scholar, Scopus, or Web of Science. Consider using multiple search terms and synonyms to cover all related topics.

4. Organize and analyze information: Develop a system for organizing and analyzing the information you find. You can use spreadsheets, note-taking applications, or reference management tools like Mendeley, Zotero, or EndNote. Categorize your sources based on themes, author’s conclusions, methodology, or other relevant criteria.

5. Write a critique of the literature: Evaluate and synthesize the information from your sources. Discuss their strengths, weaknesses, and gaps in knowledge or understanding. Point out any inconsistencies in the findings and explain any varying theories or viewpoints. Provide a balanced critique that highlights the most significant contributions, trends, or patterns.

6. Structure the review: Organize your literature review into sections that present the main themes or findings. Start with an introduction that outlines your research question, the scope of the review, and any limitations you may have encountered. Write clear, concise, and coherent summaries of your literature for each section, and end with a conclusion that synthesizes the main findings, suggests areas for further research, and reinforces your research question or hypothesis.

Incorporating these steps will assist you in crafting a well-structured, focused, and informative literature review for your research project.

Here are some examples of each step in the process. 

Top Tips on How to Write Your Literature Review

Here are the top tips on how to write your literature review, based on the Grad Coach TV video and advice from trusted coach Amy:

1. Develop a rough outline or framework before you start writing your literature review. This helps you avoid creating a jumbled mess and allows you to organize your thoughts coherently and effectively.

2. Use previous literature reviews as a guide to understand the norms and expectations in your field. Look for recently published literature reviews in academic journals or online databases, such as Google Scholar, EBSCO, or ProQuest.

3. Write first and edit later. Avoid perfectionism and don’t be afraid to create messy drafts. This helps you overcome writer’s block and ensures progress in your work.

4. Insert citations as you write to avoid losing track of references. Make sure to follow the appropriate formatting style (e.g. APA or MLA) and use reference management tools like Mendeley to easily keep track of your sources.

5. Organize your literature review logically, whether it’s chronologically, thematically, or methodologically. Identify gaps in the literature and explain how your study addresses them. Keep in mind that the structure isn’t set in stone and can change as you read and write.

Remember that writing your literature review is an iterative process, so give yourself room to improve and make changes as needed. Keep these actionable tips in mind, and you’ll be well on your way to creating a compelling and well-organized literature review.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

Common Assignments: Literature Reviews

Basics of literature reviews.

A literature review is a written approach to examining published information on a particular topic or field. Authors use this review of literature to create a foundation and justification for their research or to demonstrate knowledge on the current state of a field. This review can take the form of a course assignment or a section of a longer capstone project. Read on for more information about writing a strong literature review!

Students often misinterpret the term "literature review" to mean merely a collection of source summaries, similar to annotations or article abstracts. Although summarizing is an element of a literature review, the purpose is to create a comprehensive representation of your understanding of a topic or area of research, such as what has already been done or what has been found. Then, also using these sources, you can demonstrate the need for future research, specifically, your future research.

There is usually no required format or template for a literature review. However, there are some actions to keep in mind when constructing a literature review:

• Include an introduction and conclusion . Even if the literature review will be part of a longer document, introductory and concluding paragraphs can act as bookends to your material. Provide background information for your reader, such as including references to the pioneers in the field in the beginning and offering closure in the end by discussing the implications of future research to the field.
• Avoid direct quotations . Just like in an annotated bibliography, you will want to paraphrase all of the material you present in a literature review. This assignment is a chance for you to demonstrate your knowledge on a topic, and putting ideas into your own words will ensure that you are interpreting the found material for your reader. Paraphrasing will also ensure your review of literature is in your authorial voice.
• Organize by topic or theme rather than by author. When compiling multiple sources, a tendency can be to summarize each source and then compare and contrast the sources at the end. Instead, organize your source information by your identified themes and patterns. This organization helps demonstrate your synthesis of the material and inhibits you from creating a series of book reports.
•  Use headings . APA encourages the use of headings within longer pieces of text to display a shift in topic and create a visual break for the reader. Headings in a literature review can also help you as the writer organize your material by theme and note any layers, or subtopics, within the field.
• Show relationships and consider the flow of ideas. A literature review can be lengthy and dense, so you will want to make your text appealing to your reader. Transitions and comparison terms will allow you to demonstrate where authors agree or disagree on a topic and highlight your interpretation of the literature.

🔭 literature review outline: general information.

Literature reviews are written mostly in sciences and social sciences, and sometimes in humanities. A literature review aims to discuss published information on the studies in a particular area. The most simple version of a literature review can be a mere summary of the sources. However, it usually features an organizational pattern and implies not only summary but also synthesis.

A literature review aims to provide a reader with a clear and understandable guide to a particular research topic. And for its writer, a solid review is an excellent opportunity to show them as an expert in a chosen field.

As MLA, Chicago, or APA style cover page generators help students with the very first part of any paper, the key to a successful literature review is a good outline . When planning a literature review, remember that no matter whether you’re dealing with a Chicago, MLA, or APA literature review outline, you’ll have to remember several important things.

📑 Literature Review Outline: Approaches to Structuring

A well-formed vision of the writing strategy before you start the main body paragraphs is half of the success. There are four approaches to arranging a literature review. Depending on the intended length of your paper, you can combine some or all of them. For instance, more than often, thematic and methodological strategies comprise a theoretical approach when it comes to details.

Chronological Approach

Tracing the reviewed works in succession, starting with the earliest available materials, is the easiest way to examine the specific topic. Be careful not to list the works in chronological order with their summaries. The purpose of such a review is to find out the key patterns, central debates, and turning points of the prevailing opinion at specific periods.

Here is a sample to make the approach clear. If the first available source dates 1995, and the most recent one was written in 2017, divide your analysis into decades: 1995 – 2000, 2001 – 2010, and 2010 – present.

The chronological approach can perfectly combine with thematic or methodological ones. In such a case, the timescale is divided not by decades but by periods characterized by a predominant methodology or preferred theme.

Thematic Approach

This method is organized around a particular issue, rather than time progression. If you have found recurring themes in the course of your reading, it is an excellent idea to focus the review on them. As a rule, the thematic approach requires an in-depth study of the available scientific literature. It also looks more substantial and time-consuming than the chronological one.

Here, the sections dwell upon different issues or various aspects of one topic. For example, an overview of psychology literature on nonverbal communication can be divided into the following parts: facial expressions, postures, eye contact, gestures, touch, etc.

Methodological Approach

Sometimes the results of findings are not as outstanding as the ways of obtaining those results. A review of research methods provides a profound scientific understanding of the subject field, notably the approaches to data collection, study, and systematization. It also provides an insight into how scientists went from isolated data to a concept, and from the concept to practical conclusions.

This form proves to be the most successful in the analysis of multidisciplinary works. You can list all the methods used and conclude on their efficiency. Alternatively, you can compare the qualitative and quantitative, empirical and theoretical, or any other incompatible methodology. The materials for analysis are the results obtained by such or another method.

Theoretical Approach

Very often, a literature review becomes the basis for a theoretical framework of a research paper. In this case, the theoretical approach is the most effective way to structure the report.

Wherever you can single out several theories on a single phenomenon, different models of a system, or diverging definitions of the same concept, the theoretical approach is the best choice. The purpose is to analyze the corpus of theory that has accumulated regarding an idea, opinion, or event. Usually, this form establishes the existing scientific knowledge gaps and finds out the outstanding research questions.

✍️ Literature Review Outline: Writing Tips

When you start writing a literature review, you should keep the following issues in mind:

• Use evidence to support your interpretation of available sources.
• Be selective. Limit your literature review to sources relevant to the topic of your research. You should select only the most important points in each source.
• Compare and contrast the views of different authors. Organize the material for your reader to show trends in the literature.
• Use quotes sparingly. Apply them only when you want to emphasize the author’s point and cannot rewrite it in your own words. Always focus on giving your own summary and interpretation of the literature, showing your original thinking and analysis.
• Paraphrase in your own words to explain authors’ ideas . Give references to other sources when you are writing, but start and end the paragraphs with your own ideas.
• Summarize and synthesize your literature review sources. Identify the main points in a concise manner for your readers. Evaluate your sources , consider their strengths and weaknesses, compare and contrast the results of the studies, and discuss the strength of the evidence.
• Look for gaps in the existing research. Think about what aspects of your literature review topic have not yet been explored.
• Be creative!
• Draft and redraft. Improve the quality of your literature review by editing and proofreading.

✏️ Literature Review FAQ

The way such paper should look like is best presented in the form of an outline . A simplified form would include an introduction, 3+ paragraphs (preferably with 2+ subparagraphs in each) as a review body, and a conclusion.

You should write about your interpretation of the literary piece. Include your understanding of the author’s message and the way he puts that idea across (scenes, characters, allusions, etc.). For a research paper, however, include more precise details than personal impressions.

Outlines for a paper should list concise notes about the structure of the text and its content (usually in the format of bullet points). Remember that an outline is not a research proposal or dissertation, so do not write about the goals, objectives, methods, etc.

Do you have a list of ideas you want to describe in the paper already? If so, just make those notes structured in logical consequence and format them as bullet points highlighting the gist of each part.

HI, how long would you suggest an undergraduate’s final year research paper should be? ( minimum in pages for both quanti and quali researches) and is 15 pages of literature review( double spacing okay?

It would probably be between 10 and 20 pages. But it all comes down to the specific topic and instructions given. Fifteen pages for a literature review sounds good, if it’s an independent type of assignment. However, if it’s part of the undergraduate’s final year research paper mentioned above, then fifteen pages is probably too much. But, again, it all depends on the instructions, topic, etc.

thankyouuuu!!!!!!! best one so far

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

What Is a Literature Review?

A literature review is an integrated analysis of scholarly writings that are related directly to your research question. Put simply, it's  a critical evaluation of what's already been written on a particular topic . It represents the literature that provides background information on your topic and shows a connection between those writings and your research question.

A literature review may be a stand-alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.

What a Literature Review Is Not:

• A list or summary of sources
• An annotated bibliography
• A grouping of broad, unrelated sources
• A compilation of everything that has been written on a particular topic
• Literary criticism (think English) or a book review

Why Literature Reviews Are Important

• They explain the background of research on a topic
• They demonstrate why a topic is significant to a subject area
• They discover relationships between research studies/ideas
• They identify major themes, concepts, and researchers on a topic
• They identify critical gaps and points of disagreement
• They discuss further research questions that logically come out of the previous studies

A literature review surveys prior research published in books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have used in researching a particular topic and to demonstrate to your readers how your research fits within existing scholarship about the topic.

Importance of a Good Literature Review

A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,
• Trace the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

Given this, the purpose of a literature review is to:

• Place each work in the context of its contribution to understanding the research problem being studied.
• Describe the relationship of each work to the others under consideration.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.
• Resolve conflicts amongst seemingly contradictory previous studies.
• Identify areas of prior scholarship to prevent duplication of effort.
• Point the way in fulfilling a need for additional research.
• Locate your own research within the context of existing literature [very important].

Types of Literature Reviews

It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.

In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].

Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.

Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.

Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.

Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

NOTE: Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style

I.  Thinking About Your Literature Review

The structure of a literature review should include the following in support of understanding the research problem :

• An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
• Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
• An explanation of how each work is similar to and how it varies from the others,
• Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.

The critical evaluation of each work should consider :

• Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
• Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
• Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
• Persuasiveness -- which of the author's theses are most convincing or least convincing?
• Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II.  Development of the Literature Review

Four Basic Stages of Writing 1.  Problem formulation -- which topic or field is being examined and what are its component issues? 2.  Literature search -- finding materials relevant to the subject being explored. 3.  Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4.  Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1.  Roughly how many sources would be appropriate to include? 2.  What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3.  Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4.  Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5.  Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.

III.  Ways to Organize Your Literature Review

Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] A thematic literature review is the most common approach to summarizing prior research in the social and behavioral sciences. Thematic reviews are organized around a topic or issue, rather than the progression of time, although the progression of time may still be incorporated into a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it would still be organized chronologically reflecting technological developments in media. The difference in this example between a "chronological" and a "thematic" approach is what is emphasized the most: themes related to the role of the Internet in presidential politics. Note that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point being made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.

Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:

• Current Situation : Information necessary to understand the current topic or focus of the literature review.
• Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
• History : The chronological progression of the field, the research literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
• Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed [i.e., scholarly] sources.
• Standards : Description of the way in which you present your information.
• Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV.  Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information, but that are not key to understanding the research problem, can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.

V.  Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

• Sources in your literature review do not clearly relate to the research problem;
• You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
• Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
• Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
• Does not describe the search procedures that were used in identifying the literature to review;
• Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
• Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip

Break Out of Your Disciplinary Box!

Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Frodeman, Robert. The Oxford Handbook of Interdisciplinarity . New York: Oxford University Press, 2010.

Another Writing Tip

Don't Just Review for Content!

While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:

• How are they organizing their ideas?
• What methods have they used to study the problem?
• What theories have been used to explain, predict, or understand their research problem?
• What sources have they cited to support their conclusions?
• How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

Yet Another Writing Tip

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:

• Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research?  Does it forge a new path? Or, does is merely add more of the same thing being said?
• Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
• Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

How to Write a Literature Review

As every student knows, writing informative essay and research papers is an integral part of the educational program. You create a thesis, support it using valid sources, and formulate systematic ideas surrounding it. However, not all students know that they will also have to face another type of paper known as a Literature Review in college. Let's take a closer look at this with our custom essay writer .

Literature Review Definition

As this is a less common academic writing type, students often ask: "What is a literature review?" According to the definition, a literature review is a body of work that explores various publications within a specific subject area and sometimes within a set timeframe.

This type of writing requires you to read and analyze various sources that relate to the main subject and present each unique comprehension of the publications. Lastly, a literature review should combine a summary with a synthesis of the documents used. A summary is a brief overview of the important information in the publication; a synthesis is a re-organization of the information that gives the writing a new and unique meaning.

Typically, a literature review is a part of a larger paper, such as a thesis or dissertation. However, you may also be given it as a stand-alone assignment.

The Purpose

The main purpose of a literature review is to summarize and synthesize the ideas created by previous authors without implementing personal opinions or other additional information.

However, a literature review objective is not just to list summaries of sources; rather, it is to notice a central trend or principle in all of the publications. Just like a research paper has a thesis that guides it on rails, a literature review has the main organizing principle (MOP). The goal of this type of academic writing is to identify the MOP and show how it exists in all of your supporting documents.

Why is a literature review important? The value of such work is explained by the following goals it pursues:

• Highlights the significance of the main topic within a specific subject area.
• Demonstrates and explains the background of research for a particular subject matter.
• Helps to find out the key themes, principles, concepts, and researchers that exist within a topic.
• Helps to reveal relationships between existing ideas/studies on a topic.
• Reveals the main points of controversy and gaps within a topic.
• Suggests questions to drive primary research based on previous studies.

Here are some example topics for writing literature reviews:

• Exploring racism in "To Kill a Mockingbird," "The Adventures of Huckleberry Finn," and "Uncle Tom's Cabin."
• Isolationism in "The Catcher in the Rye," "Frankenstein," and "1984"
• Understanding Moral Dilemmas in "Crime and Punishment," "The Scarlet Letter," and "The Lifeboat"
• Corruption of Power in "Macbeth," "All the King's Men," and "Animal Farm"
• Emotional and Physical survival in "Lord of the Flies," "Hatchet," and "Congo."

How Long Is a Literature Review?

When facing the need to write a literature review, students tend to wonder, "how long should a literature review be?" In some cases, the length of your paper's body may be determined by your instructor. Be sure to read the guidelines carefully to learn what is expected from you.

Keeping your literature review around 15-30% of your entire paper is recommended if you haven't been provided with specific guidelines. To give you a rough idea, that is about 2-3 pages for a 15-page paper. In case you are writing a literature review as a stand-alone assignment, its length should be specified in the instructions provided.

Literature Review Format: APA, MLA, and Chicago

The essay format you use should adhere to the citation style preferred by your instructor. Seek clarification from your instructor for several other components as well to establish a desired literature review format:

• How many sources should you review, and what kind of sources should they be (published materials, journal articles, or websites)?
• What format should you use to cite the sources?
• How long should the review be?
• Should your review consist of a summary, synthesis, or a personal critique?
• Should your review include subheadings or background information for your sources?

If you want to format your paper in APA style, then follow these rules:

• Use 1-inch page margins.
• Unless provided with other instructions, use double-spacing throughout the whole text.
• Make sure you choose a readable font. The preferred font for APA papers is Times New Roman set to 12-point size.
• Include a header at the top of every page (in capital letters). The page header must be a shortened version of your essay title and limited to 50 characters, including spacing and punctuation.
• Put page numbers in the upper right corner of every page.
• When shaping your literature review outline in APA, don't forget to include a title page. This page should include the paper's name, the author's name, and the institutional affiliation. Your title must be typed with upper and lowercase letters and centered in the upper part of the page; use no more than 12 words, and avoid using abbreviations and useless words.

For MLA style text, apply the following guidelines:

• Double your spacing across the entire paper.
• Set ½-inch indents for each new paragraph.
• The preferred font for MLA papers is Times New Roman set to 12-point size.
• Include a header at the top of your paper's first page or on the title page (note that MLA style does not require you to have a title page, but you are allowed to decide to include one). A header in this format should include your full name; the name of your instructor; the name of the class, course, or section number; and the due date of the assignment.
• Include a running head in the top right corner of each page in your paper. Place it one inch from the page's right margin and half an inch from the top margin. Only include your last name and the page number separated by a space in the running head. Do not put the abbreviation p. before page numbers.

Finally, if you are required to write a literature review in Chicago style, here are the key rules to follow:

• Set page margins to no less than 1 inch.
• Use double spacing across the entire text, except when it comes to table titles, figure captions, notes, blockquotes, and entries within the bibliography or References.
• Do not put spaces between paragraphs.
• Make sure you choose a clear and easily-readable font. The preferred fonts for Chicago papers are Times New Roman and Courier, set to no less than 10-point size, but preferably to 12-point size.
• A cover (title) page should include your full name, class information, and the date. Center the cover page and place it one-third below the top of the page.
• Place page numbers in the upper right corner of each page, including the cover page.

Structure of a Literature Review

How to structure a literature review: Like many other types of academic writing, a literature review follows a typical intro-body-conclusion style with 5 paragraphs overall. Now, let’s look at each component of the basic literature review structure in detail:

• Introduction

You should direct your reader(s) towards the MOP (main organizing principle). This means that your information must start from a broad perspective and gradually narrow down until it reaches your focal point.

Start by presenting your general concept (Corruption, for example). After the initial presentation, narrow your introduction's focus towards the MOP by mentioning the criteria you used to select the literature sources you have chosen (Macbeth, All the King's Men, and Animal Farm). Finally, the introduction will end with the presentation of your MOP that should directly link it to all three literature sources.

Body Paragraphs

Generally, each body paragraph will focus on a specific source of literature laid out in the essay's introduction. As each source has its own frame of reference for the MOP, it is crucial to structure the review in the most logically consistent way possible. This means the writing should be structured chronologically, thematically or methodologically.

Chronologically

Breaking down your sources based on their publication date is a solid way to keep a correct historical timeline. If applied properly, it can present the development of a certain concept over time and provide examples in the form of literature. However, sometimes there are better alternatives we can use to structure the body.

Thematically

Instead of taking the "timeline approach," another option can be looking at the link between your MOP and your sources. Sometimes, the main idea will just glare from a piece of literature. Other times, the author may have to seek examples to prove their point. An experienced writer will usually present their sources by order of strength. For example, in "To Kill A Mockingbird," the entire novel was centralized around racism; in "The Adventures of Huckleberry Finn," racism was one of many themes.

Methodologically

As made obvious by the terminology, this type of structuring focuses on the methods used to present the central concept. For example, in "1984", George Orwell uses the law-and-order approach and shows the dangers of a dystopia for a social species.

In "Frankenstein," Mary Shelley exposes the character's physical traits as repulsive and horrifying, forcing him to suffer in an isolated environment. By showcasing the various methods used to portray the MOP, the writer can compare them based on things like severity, ethicality, and overall impact.

After presenting your key findings in the body paragraphs, there are 3 final objectives to complete in the essay's conclusion. First, the author should summarize the findings they have made or found, in other words, and briefly answer the question: "What have you learned?"

After discussing that information, the next step is to present the significance of the information about our current world today. In other words, how can the reader take the information and apply it to today's society? From that point, we finish off with a breadcrumb trail.

As the author, you want to leave the readers' trail of thought within the actual essay topic. This provides them with a means of further investigation—meaning that the reader may consider where the discussion will go next.

Writing an Outline for a Literature Review

Students often underestimate the importance of planning the structure of their papers in advance. However, this is not a wise approach. Having a rough APA literature review outline (or other style outlines) will not only help you follow the right format and structure but will also make the writing process simpler and help ensure that you include all of the important information without missing anything.

How to write a literature review outline: As you already know from the Structure section of this guide, every part of your literature review performs its own important role. Therefore, you should create your outline while keeping the general introduction-body-conclusion structure in mind and ensuring that each section meets its own objectives. However, it is important to remember that a literature review outline is slightly different from outlines of other types of essays because it does not provide new information. Instead, it focuses on existing studies relevant to the main topic. ‍

Here is a literature review outline example on the subject of the Ebola virus to help you get it right:

• Introduce the general topic. Provide background information on the Ebola virus: genome, pathogenesis, transmission, epidemiology, treatment, etc.
• Shape the main research question: What is the potential role of arthropods (mechanical or biological vectors) in the distribution of the Ebola virus?
• Methodology: For example, the information was searched through X databases to find relevant research articles about the Ebola virus and arthropods' role in its spreading. The data was extracted using a standardized form.
• Expected outcomes
• Overall trends in the literature on this topic: While the natural reservoir of the virus is still not known with certainty, many researchers believe that arthropods (and fruit bats, in particular) pay a significant role in the distribution of the virus.
• Subject 1: A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Subject 2: A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Subject 3:  A brief overview of the particular piece of literature in general terms; an analysis of the key aspects of the study; a review of the research questions, methods, procedures, and outcomes; and an overview of the strong and weak points, gaps, and contradictions.
• Indicate the relationships between the pieces of literature discussed. Emphasize key themes, common patterns, and trends. Talk about the pros and cons of the different approaches taken by the authors/researchers.
• State which studies seem to be the most influential.
• Emphasize the major contradictions and points of disagreement. Define the gaps still to be covered (if any).
• If applicable: define how your own study will contribute to further disclosure of the topic.

Hopefully, this sample outline will help you to structure your own paper. However, if you feel like you need some more advice on how to organize your review, don’t hesitate to search for more literature review outline examples in APA or other styles on the Web, or simply ask our writers to get a dissertation help .

How to Write a Good Literature Review

Whether you are writing a literature review within the framework of a large research project (e.g. thesis, dissertation, or other) or as a stand-alone assignment, the approach you should take to writing generally remains the same.

Whether you are writing a literature review within the framework of a large research project (e.g., thesis, dissertation, or other) or as a stand-alone assignment, the approach you should take to writing generally remains the same.

Now, as you know about the general rules and have a basic literature review outline template, let's define the steps to take to handle this task right with our service:

Step 1: Identifying the Topic

This is probably the only matter you may approach differently depending on whether your literature review comes within a research paper or a separate assignment altogether. If you are creating a literature review as a part of another work, you need to search for literature related to your main research questions and problems. Respectively, if you are writing it as a stand-alone task, you will have to pick a relevant topic and central question upon which you will collect the literature. Earlier in this guide, we suggested some engaging topics to guide your search.

Step 2: Conducting Research

When you have a clearly defined topic, it is time to start collecting literature for your review. We recommend starting by compiling a list of relevant keywords related to your central question—to make the entire research process much simpler and help you find relevant publications faster.

When you have a list of keywords, use them to search for valid and relevant sources. At this point, be sure to use only trusted sources, such as ones from university libraries, online scientific databases, etc.

Once you have found some sources, be sure to define whether or not they are actually relevant to your topic and research question. To save time, you can read abstracts to get general ideas of what the papers are about instead of the whole thing.

Pro Tip: When you finally find a few valid publications, take a look at their bibliographies to discover other relevant sources as well.

Step 3: Assess and Prioritize Sources

Throughout your research, you will likely find plenty of relevant literature to include in your literature review. At this point, students often make the mistake of trying to fit all the collected sources into their reviews. Instead, we suggest looking at what you've collected once more, evaluating the available sources, and selecting the most relevant ones. You most likely won't be able to read everything you find on a given topic and then be able to synthesize all of the sources into a single literature review. That's why prioritizing them is important.

To evaluate which sources are worth including in your review, keep in mind the following criteria:

• Credibility;
• Innovation;
• Key insights;

Furthermore, as you read the sources, don’t forget to take notes on everything you can incorporate into the review later. And be sure to get your citations in place early on. If you cite the selected sources at the initial stage, you will find it easier to create your annotated bibliography later on.

Step 4: Identify Relationships, Key Ideas, and Gaps

Before you can move on to outlining and writing your literature review, the final step is determining the relationships between the studies that already exist. Identifying the relationships will help you organize the existing knowledge, build a solid literature outline, and (if necessary) indicate your own research contribution to a specific field.

Some of the key points to keep an eye out for are:

• Main themes;
• Contradictions and debates;
• Influential studies or theories;
• Trends and patterns;

Here are a few examples: Common trends may include a focus on specific groups of people across different studies. Most researchers may have increased interest in certain aspects of the topic regarding key themes. Contradictions may include some disagreement concerning the theories and outcomes of a study. And finally, gaps most often refer to a lack of research on certain aspects of a topic.

Step 5: Make an Outline

Although students tend to neglect this stage, outlining is one of the most important steps in writing every academic paper. This is the easiest way to organize the body of your text and ensure that you haven't missed anything important. Besides, having a rough idea of what you will write about in the paper will help you get it right faster and more easily. Earlier in this guide, we already discussed the basic structure of a literature review and gave you an example of a good outline. At this workflow stage, you can use all of the knowledge you've gained from us to build your own outline.

Step 6: Move on to Writing

Having found and created all of your sources, notes, citations, and a detailed outline, you can finally get to the writing part of the process. At this stage, all you need to do is follow the plan you've created and keep in mind the overall structure and format defined in your professor's instructions.

Step 7: Adding the Final Touches

Most students make a common mistake and skip the final stage of the process, which includes proofreading and editing. We recommend taking enough time for these steps to ensure that your work will be worth the highest score. Do not underestimate the importance of proofreading and editing, and allocate enough time for these steps.

Pro Tip: Before moving on to proofreading and editing, be sure to set your literature review aside for a day or two. This will give you a chance to take your mind off it and then get back to proofreading with a fresh perspective. This tip will ensure that you won't miss out on any gaps or errors that might be present in your text.

These steps will help you create a top-notch literature review with ease! Want to get more advice on how to handle this body of work? Here are the top 3 tips you need to keep in mind when writing a literature review:

1. Good Sources

When working on a literature review, the most important thing any writer should remember is to find the best possible sources for their MOP. This means that you should select and filter through about 5-10 different options while doing initial research.

The stronger a piece of literature showcases the central point, the better the quality of the entire review.

2. Synthesize The Literature

Make sure to structure the review in the most effective way possible, whether it be chronologically, thematically, or methodologically. Understand what exactly you would like to say, and structure the source comparison accordingly.

3. Avoid Generalizations

Remember that each piece of literature will approach the MOP from a different angle. As the author, make sure to present the contrasts in approaches clearly and don't include general statements that offer no value.

Literature Review Examples

The best way to approach your literature review is to break it down into steps.  Remember, research is an iterative process, not a linear one.  You will revisit steps and revise along the way.  Get started with the handout, information, and tips from various university Writing Centers below that provides an excellent overview.  Then move on to the specific steps recommended on this page.

• UNC- Chapel Hill Writing Center Literature Review Handout, from the University of North Carolina at Chapel Hill.
• University of Wisconsin-Madison Writing Center Learn how to write a review of literature, from the University of Wisconsin-Madison.
• University of Toronto-- Writing Advice The Literature Review: A few tips on conducting it, from the University of Toronto.
• Begin with a topic.
• Understand the topic. 
• Familiarize yourself with the terminology.  Note what words are being used and keep track of these for use as database search keywords. 
• See what research has been done on this topic before you commit to the topic.  Review articles can be helpful to understand what research has been done .
• Develop your research question.  (see handout below)
• How comprehensive should it be? 
• Is it for a course assignment or a dissertation? 
• How many years should it cover?
• Developing a good nursing research question Handout. Reviews PICO method and provides search tips.

Your next step is to construct a search strategy and then locate & retrieve articles.

•  There are often 2-4 key concepts in a research question.
• Search for primary sources (original research articles.)
• These are based on the key concepts in your research question.
• Remember to consider synonyms and related terms.
• Which databases to search?
• What limiters should be applied (peer-reviewed, publication date, geographic location, etc.)?

Review articles (secondary sources)

Use to identify literature on your topic, the way you would use a bibliography.  Then locate and retrieve the original studies discussed in the review article. Review articles are considered secondary sources.

• Once you have some relevant articles, review reference lists to see if there are any useful articles.
• Which articles were written later and have cited some of your useful articles?  Are these, in turn, articles that will be useful to you? 
• Keep track of what terms you used and what databases you searched. 
• Use database tools such as save search history in EBSCO to help.
• Keep track of the citations for the articles you will be using in your literature review. 
• Use RefWorks or another method of tracking this information. 
• Database Search Strategy Worksheet Handout. How to construct a search.
• TUTORIAL: How to do a search based on your research question This is a self-paced, interactive tutorial that reviews how to construct and perform a database search in CINAHL.

The next step is to read, review, and understand the articles.

• Start by reviewing abstracts. 
• Make sure you are selecting primary sources (original research articles).
• Note any keywords authors report using when searching for prior studies.
• You will need to evaluate and critique them and write a synthesis related to your research question.
• Consider using a matrix to organize and compare and contrast the articles . 
• Which authors are conducting research in this area?  Search by author.  
• Are there certain authors’ whose work is cited in many of your articles?  Did they write an early, seminal article that is often cited?
• Searching is a cyclical process where you will run searches, review results, modify searches, run again, review again, etc. 
• Critique articles.  Keep or exclude based on whether they are relevant to your research question.
• When you have done a thorough search using several databases plus Google Scholar, using appropriate keywords or subject terms, plus author’s names, and you begin to find the same articles over and over.
• Remember to consider the scope of your project and the length of your paper.  A dissertation will have a more exhaustive literature review than an 8 page paper, for example.
• What are common findings among each group or where do they disagree? 
• Identify common themes. Identify controversial or problematic areas in the research. 
• Use your matrix to organize this.
• Once you have read and re-read your articles and organized your findings, you are ready to begin the process of writing the literature review.

2. Synthesize.  (see handout below)

• Include a synthesis of the articles you have chosen for your literature review.
• A literature review is NOT a list or a summary of what has been written on a particular topic. 
• It analyzes the articles in terms of how they relate to your research question. 
• While reading, look for similarities and differences (compare and contrast) among the articles.  You will create your synthesis from this.
• Synthesis Examples Handout. Sample excerpts that illustrate synthesis.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.
