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 that you can later apply to your paper, thesis, or dissertation topic .

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 summarize sources—it analyzes, synthesizes , 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 thesis , dissertation , or research paper , you will likely 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 its scholarly context
Develop a theoretical framework and methodology for your research
Position your work in relation to other researchers and theorists
Show how your research addresses a gap or contributes to a debate
Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

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 problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. 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 as 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 useful 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 also use boolean operators to help narrow down your search.

Make sure to 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.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

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?
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 use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

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 is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation 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.

To begin organizing your literature review’s argument and structure, be sure you 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 organizing the body of a literature review. 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 summarizing sources in order.

Try to analyze 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 organize 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.

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, you can follow these tips:

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 sentences to draw connections, comparisons and contrasts

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

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 thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

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

To familiarize 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 thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .

An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

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.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

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.

How to Write a Literature Review: Six Steps to Get You from Start to Finish

Writing-a-literature-review-six-steps-to-get-you-from-start-to-finish.

Tanya Golash-Boza, Associate Professor of Sociology, University of California

February 03, 2022

Writing a literature review is often the most daunting part of writing an article, book, thesis, or dissertation. “The literature” seems (and often is) massive. I have found it helpful to be as systematic as possible when completing this gargantuan task.

Sonja Foss and William Walters* describe an efficient and effective way of writing a literature review. Their system provides an excellent guide for getting through the massive amounts of literature for any purpose: in a dissertation, an M.A. thesis, or preparing a research article for publication in any field of study. Below is a summary of the steps they outline as well as a step-by-step method for writing a literature review.

How to Write a Literature Review

Step One: Decide on your areas of research:

Before you begin to search for articles or books, decide beforehand what areas you are going to research. Make sure that you only get articles and books in those areas, even if you come across fascinating books in other areas. A literature review I am currently working on, for example, explores barriers to higher education for undocumented students.

Step Two: Search for the literature:

Conduct a comprehensive bibliographic search of books and articles in your area. Read the abstracts online and download and/or print those articles that pertain to your area of research. Find books in the library that are relevant and check them out. Set a specific time frame for how long you will search. It should not take more than two or three dedicated sessions.

Step Three: Find relevant excerpts in your books and articles:

Skim the contents of each book and article and look specifically for these five things:

1. Claims, conclusions, and findings about the constructs you are investigating

2. Definitions of terms

3. Calls for follow-up studies relevant to your project

4. Gaps you notice in the literature

5. Disagreement about the constructs you are investigating

When you find any of these five things, type the relevant excerpt directly into a Word document. Don’t summarize, as summarizing takes longer than simply typing the excerpt. Make sure to note the name of the author and the page number following each excerpt. Do this for each article and book that you have in your stack of literature. When you are done, print out your excerpts.

Step Four: Code the literature:

Get out a pair of scissors and cut each excerpt out. Now, sort the pieces of paper into similar topics. Figure out what the main themes are. Place each excerpt into a themed pile. Make sure each note goes into a pile. If there are excerpts that you can’t figure out where they belong, separate those and go over them again at the end to see if you need new categories. When you finish, place each stack of notes into an envelope labeled with the name of the theme.

Step Five: Create Your Conceptual Schema:

Type, in large font, the name of each of your coded themes. Print this out, and cut the titles into individual slips of paper. Take the slips of paper to a table or large workspace and figure out the best way to organize them. Are there ideas that go together or that are in dialogue with each other? Are there ideas that contradict each other? Move around the slips of paper until you come up with a way of organizing the codes that makes sense. Write the conceptual schema down before you forget or someone cleans up your slips of paper.

Step Six: Begin to Write Your Literature Review:

Choose any section of your conceptual schema to begin with. You can begin anywhere, because you already know the order. Find the envelope with the excerpts in them and lay them on the table in front of you. Figure out a mini-conceptual schema based on that theme by grouping together those excerpts that say the same thing. Use that mini-conceptual schema to write up your literature review based on the excerpts that you have in front of you. Don’t forget to include the citations as you write, so as not to lose track of who said what. Repeat this for each section of your literature review.

Once you complete these six steps, you will have a complete draft of your literature review. The great thing about this process is that it breaks down into manageable steps something that seems enormous: writing a literature review.

I think that Foss and Walter’s system for writing the literature review is ideal for a dissertation, because a Ph.D. candidate has already read widely in his or her field through graduate seminars and comprehensive exams.

It may be more challenging for M.A. students, unless you are already familiar with the literature. It is always hard to figure out how much you need to read for deep meaning, and how much you just need to know what others have said. That balance will depend on how much you already know.

For people writing literature reviews for articles or books, this system also could work, especially when you are writing in a field with which you are already familiar. The mere fact of having a system can make the literature review seem much less daunting, so I recommend this system for anyone who feels overwhelmed by the prospect of writing a literature review.

How to write an effective literature review: Tips and tricks for a comprehensive analysis

Writing a literature review is an essential part of academic research. It helps you to identify the existing knowledge in your field and assess the strengths and weaknesses of the research conducted so far. A literature review is not just a summary of the existing literature, but it also involves a critical analysis of the literature. In this article, we will provide you with some tips and tricks to help you write an effective literature review that provides a comprehensive analysis of the existing literature.

Understand the Purpose of the Literature Review

Before you start writing your literature review, it’s essential to understand its purpose. The primary purpose of a literature review is to provide an overview of the existing research in your field. It should highlight the gaps in the research and identify the areas that need further investigation . A literature review should also demonstrate your knowledge of the field and your ability to analyze the existing research critically.

Conduct a Thorough Literature Search

To write an effective literature review, you need to conduct a thorough literature search. Start by identifying the keywords and phrases that relate to your research topic. You can use online databases, such as Google Scholar or PubMed, to search for relevant articles, books, and other literature. It’s also a good idea to look at the reference lists of the articles you find to identify other relevant literature.

Read and Take Notes

Once you have identified the relevant literature, it’s time to start reading and taking notes. Make sure you read the articles thoroughly and take notes on the key points and findings. It’s essential to organize your notes in a way that makes sense to you. You can use a spreadsheet, a mind map, or any other tool that helps you organize your thoughts and ideas.

Organize Your Literature Review

Organizing your literature review is crucial to ensure that it flows logically and provides a comprehensive analysis of the existing research. Start by creating an outline of your literature review, including the key sections and the subheadings. You can use the following structure for your literature review:

Introduction: This section should provide an overview of your research topic and the purpose of your literature review.

Steps in Conducting a Literature Review

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.

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.

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.

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.

Prevent plagiarism, run a free check.

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.

Methodological

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 .

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:

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.

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.

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.

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.

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:

	Annotated Bibliography	Literature Review
Purpose	List of citations of books, articles, and other sources with a brief description (annotation) of each source.	Comprehensive and critical analysis of existing literature on a specific topic.
Focus	Summary and evaluation of each source, including its relevance, methodology, and key findings.	Provides an overview of the current state of knowledge on a particular subject and identifies gaps, trends, and patterns in existing literature.
Structure	Each citation is followed by a concise paragraph (annotation) that describes the source’s content, methodology, and its contribution to the topic.	The literature review is organized thematically or chronologically and involves a synthesis of the findings from different sources to build a narrative or argument.
Length	Typically 100-200 words	Length of literature review ranges from a few pages to several chapters
Independence	Each source is treated separately, with less emphasis on synthesizing the information across sources.	The writer synthesizes information from multiple sources to present a cohesive overview of the topic.

7 easy steps to do a literature review

A literature review is a fundamental part of your thesis writing process. It critically informs you of the relevant literature by other scholars in your research area and situates your research in the conversation. Ultimately, the literature review helps you communicate how the new knowledge you are producing contributes to existing scholarship.

The process of scanning literature in your area allows you to identify overlooked or understudied topics in your research field, and identify scholarships that support your arguments. The literature review provides the theoretical framework, methodology, concepts and problems that frame your research design.

We attended the GradProSkills webinar Writing a Literature Review (GPLL37) , led by Joseph Brito, a Ph.D. Candidate in the Department of Religions and Cultures, to learn how to do a literature review efficiently and still be thorough. Joseph shared 7 steps to do a literature review in a stress-free manner:

1. Define your research scope

Establish the research area, topics and questions you want to address. Make a list of keywords (including synonyms) and main concepts linked to your research topic, and establish the connections between these concepts and your research question with a concept map . Then set some additional parameters to your searches like publication date, geographical coverage, and related disciplines.

2. Plan your research approach

Build a checklist with important aspects of your research area, like the existing scholarship covering your topic, under-researched or overlooked aspects by other researchers, and key scholars in the field. Identify where to search for research papers on Concordia’s online catalogue and databases , browse on Google Scholar , talk to a subject librarian or ask your advisor for tips. Identify credible scholarly publications like peer-reviewed journals, books from university presses and graduate thesis. If in doubt, seek your supervisor’s guidance to acceptable sources.

3. Search strategically: be efficient but thorough

Use the keywords and concepts you identified in your research and explore combinations with boolean operators (or, and, not, etc), and truncated terms (develop* returns results like development, developer). Enhance your research expertise with GradProSkills webinar Library Skills & Resources (GPLL231) or chat with Concordia's librarians .

Keep research logs with critical aspects of your search: date, database, terms used and their combinations, and results. Establish categories for important themes, and organize search results within these major themes.

4. Manage your literature with online tools

Keeping good referencing practices early on in your grad school saves you time during the writing phase. Zotero is a free online reference management tool to keep your citations and personal notes in one place. This software inserts the citation (author, date of publication, page number) into your word document and automatically creates a reference list as per the chosen citation style . Zotero training is available to grad students with GradProSkills webinar GPLL 243 - Using Zotero for Grads .

5. Critical reading and analysis

Before reading your text, consider the author's argumentation and evidence to support your research question. Skim read the abstract, conclusion, and the first sentence of each paragraph to eliminate non-relevant literature.

Keep an annotated bibliography for each source with its key points and importance to your research (about seven sentences), and place selected literature in conversation with each other. The literature review is an iterative process of searching, reading, taking notes and writing.

6. Benchmark from other literature reviews

Check existing literature reviews in the thesis and dissertations at Concordia’s Theses, dissertations, and research papers database . Organize the literature review keeping the connection between topics, with a smooth transition from one section to another. Avoid excessive direct quoting, and prefer to give your interpretation of other scholars’ perspectives in your research field.

7. Assemble the texts and write

Put all the sources together into your literature review when you are confident that you have covered the significant authors and debates in your field. You will know that you have reached this point when your search results and readings start repeating themselves, or if your advisor tells you to stop and write. A literature review is structured with an introduction, main body and conclusion. Concordia’s Student Success Centre shares handouts on how to structure essays and research papers .

Joseph recommends starting the literature review process sooner rather than later to give yourself time to gather and analyze your sources. Manage the process like a small project with specific goals and timelines to increase efficiency and reduce stress. You can learn how to work efficiently with our Productivity in Grad School (GPLL50) webinar.

How to do an Effective Literature review

How to do an effective literature review with Scholarcy

In our recent article: Five pitfalls to look out for when doing your literature review , we talked about some of the challenges researchers and students face when it comes to evaluating the articles that will be most for their own work. This can be a daunting task even for experienced researchers because of the sheer volume of literature out there.There’s no shortage of discovery services available that can return pages of search results, even for obscure terms. But once you’ve collected all those papers that look relevant, how do you figure out which ones will be most useful to you, without attempting to read them all in full? The good news is that in recent years technology has really developed not only to help you find valuable research but also to digest and absorb that research more easily.

Generate summaries from a collection of papers to review more easily

There are a few different ways you can use Scholarcy to automatically generate summaries from a collection of papers. Whether you want to upload an entire folder of papers you’ve been saving over time or import a set of results from a recent search, this can be done really quickly by doing one of the following:

Export search results from research platforms such as PubMed and import into Scholarcy.
Create an RSS feed from a research platform using a keyword/search term so that Scholarcy continually pulls in any related articles and generates summaries from these in the background.
Upload a folder full of papers from your Dropbox or Google Drive.
Upload a .RIS file of references from your reference management tool such as EndNote to generate summary flashcards from a bibliography.

Turn your search results into article summaries

Today we’re going to focus on how Scholarcy can help you with your literature review by turning your results from search engines such as PubMed into a set of summary flashcards that you can read, share and annotate on any device.We’ll take PubMed as an example but you can use this technique with any research platform that can export search results as a .ris or .nbib file.

First, run a simple search using, for example, the name of a drug or a medical condition eg. “Cancer immunotherapy”. Apply the necessary filters to your search such as publication date as well as selecting articles that have a free, full text version available.

Tips for systematic screening now that you’ve generated your summaries

Whether you choose to import search results from a service such as PubMed; set up a direct RSS feed to automatically import the latest papers to Scholarcy; or upload a folder full of articles from Dropbox, the output is the same and there are a number of ways this distilled content can help you assimilate new and complex information without running the risk of missing something important.Scholarcy summaries are structured in a consistent way to help you pull out and assess the most significant information from a paper more easily. They can also make key findings and results from similar papers easier to compare. So now that you’ve generated summaries from the long list of articles you want to assess for your literature review, what’s the best way to systematically screen these?

Assignment writing

A literature review critically analyses existing literature to develop an argument.

Writing a literature review can be challenging because:

you need to coordinate many sources and ideas into a logical argument
you may be dealing with language and ideas you haven't fully mastered yet
there are no fixed rules for what to include or how to organise your writing.

This is just a general guide to help you write a literature review. The specific requirements for your course may be different. Make sure you read through any assignment requirements carefully and ask your lecturer or tutor if you're unsure how to meet them.

Purpose of a literature review

A literature review should demonstrate your overall understanding of the literature and develop an argument, often by answering specific questions. It shouldn't just list and summarise what you've read.

Unlike other assignment types, you're often expected to determine the purpose of a literature review yourself.

Commonly, a literature review is written to help develop and justify a novel research question. But they have many other uses. For example, you may use a literature review to develop an argument that:

justifies the significance or interest of a research question
demonstrates your professional competence in a field of research
critically reviews theory or methodological approaches
weighs evidence to reach a conclusion or recommendation.

Selecting relevant materials

Your literature review should only include relevant materials, and it should be clear how each work is relevant to your main argument.

When selecting materials you should:

read widely – don't just cite papers produced by a particular research group, or from only one country or continent.
use up-to-date material – if you're completing a PhD or MPhil, you'll need to update your confirmation literature review for your final thesis.
include relevant landmark studies – show that you know the influential and highly cited works in your field, but make sure they're relevant to your argument.
limit background information – only include background details that are needed to orient the reader and help them appreciate your argument.
include as much evidence as needed – be selective about what you include, even if you're building on, updating or challenging previous work. To challenge a common assumption, include a representative list of papers to demonstrate that it's common; you don't have to list every paper that makes the assumption.

Analysing the literature

Your literature review should provide a detailed justification for your main argument. You need to critically review the literature and synthesise your analysis into a logical argument.

This general process may help:

familiarise yourself with the literature to learn what's been done and what's already known
organise the materials around themes, issues or questions rather than individual papers
critically review the information to identify things like assumptions, limitations, deficiencies, lack of clarity, methodological weaknesses, gaps, controversies and problems in existing knowledge or practice that need to be addressed.

Organising your argument

Your literature review should be a logical, well-structured argument organised into an introduction, body and conclusion.

To help organise your argument:

plan before you start writing – creating a mind map or outline can help to clarify your thinking before you start drafting.
refine as you write – give yourself time to write many drafts, and refine the writing and structure of your argument as you go. Look for repetition and common themes.

Reviewing literature for research: Doing it the right way

Shital amin poojary.

Department of Dermatology, K J Somaiya Medical College, Mumbai, Maharashtra, India

Jimish Deepak Bagadia

In an era of information overload, it is important to know how to obtain the required information and also to ensure that it is reliable information. Hence, it is essential to understand how to perform a systematic literature search. This article focuses on reliable literature sources and how to make optimum use of these in dermatology and venereology.

INTRODUCTION

A thorough review of literature is not only essential for selecting research topics, but also enables the right applicability of a research project. Most importantly, a good literature search is the cornerstone of practice of evidence based medicine. Today, everything is available at the click of a mouse or at the tip of the fingertips (or the stylus). Google is often the Go-To search website, the supposed answer to all questions in the universe. However, the deluge of information available comes with its own set of problems; how much of it is actually reliable information? How much are the search results that the search string threw up actually relevant? Did we actually find what we were looking for? Lack of a systematic approach can lead to a literature review ending up as a time-consuming and at times frustrating process. Hence, whether it is for research projects, theses/dissertations, case studies/reports or mere wish to obtain information; knowing where to look, and more importantly, how to look, is of prime importance today.

Literature search

Fink has defined research literature review as a “systematic, explicit and reproducible method for identifying, evaluating, and synthesizing the existing body of completed and recorded work produced by researchers, scholars and practitioners.”[ 1 ]

Review of research literature can be summarized into a seven step process: (i) Selecting research questions/purpose of the literature review (ii) Selecting your sources (iii) Choosing search terms (iv) Running your search (v) Applying practical screening criteria (vi) Applying methodological screening criteria/quality appraisal (vii) Synthesizing the results.[ 1 ]

This article will primarily concentrate on refining techniques of literature search.

Sources for literature search are enumerated in Table 1 .

Sources for literature search

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g001.jpg

PubMed is currently the most widely used among these as it contains over 23 million citations for biomedical literature and has been made available free by National Center for Biotechnology Information (NCBI), U.S. National Library of Medicine. However, the availability of free full text articles depends on the sources. Use of options such as advanced search, medical subject headings (MeSH) terms, free full text, PubMed tutorials, and single citation matcher makes the database extremely user-friendly [ Figure 1 ]. It can also be accessed on the go through mobiles using “PubMed Mobile.” One can also create own account in NCBI to save searches and to use certain PubMed tools.

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g002.jpg

Tips for efficient use of PubMed search:[ 2 , 3 , 4 ]

Use of field and Boolean operators

When one searches using key words, all articles containing the words show up, many of which may not be related to the topic. Hence, the use of operators while searching makes the search more specific and less cumbersome. Operators are of two types: Field operators and Boolean operators, the latter enabling us to combine more than one concept, thereby making the search highly accurate. A few key operators that can be used in PubMed are shown in Tables Tables2 2 and and3 3 and illustrated in Figures Figures2 2 and and3 3 .

Field operators used in PubMed search

Boolean operators used in PubMed search

PubMed search using Boolean operators ‘AND’, ‘NOT’; To search for articles on treatment of lepra reaction other than steroids, after clicking the option ‘Advanced search’ on the home page, one can build the search using ‘AND’ option for treatment and ‘NOT’ option for steroids to omit articles on steroid treatment in lepra reaction

Use of medical subject headings terms

These are very specific and standardized terms used by indexers to describe every article in PubMed and are added to the record of every article. A search using MeSH will show all articles about the topic (or keywords), but will not show articles only containing these keywords (these articles may be about an entirely different topic, but still may contain your keywords in another context in any part of the article). This will make your search more specific. Within the topic, specific subheadings can be added to the search builder to refine your search [ Figure 4 ]. For example, MeSH terms for treatment are therapy and therapeutics.

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g007.jpg

PubMed search using medical subject headings (MeSH) terms for management of gonorrhea. Click on MeSH database ( Figure 1 ) →In the MeSH search box type gonorrhea and click search. Under the MeSH term gonorrhea, there will be a list of subheadings; therapy, prevention and control, click the relevant check boxes and add to search builder →Click on search →All articles on therapy, prevention and control of gonorrhea will be displayed. Below the subheadings, there are two options: (1) Restrict to medical subject headings (MeSH) major topic and (2) do not include MeSH terms found below this term in the MeSH hierarchy. These can be used to further refine the search results so that only articles which are majorly about treatment of gonorrhea will be displayed

Two additional options can be used to further refine MeSH searches. These are located below the subheadings for a MeSH term: (1) Restrict to MeSH major topic; checking this box will retrieve articles which are majorly about the search term and are therefore, more focused and (2) Do not include MeSH terms found below this term in the MeSH hierarchy. This option will again give you more focused articles as it excludes the lower specific terms [ Figure 4 ].

Similar feature is available with Cochrane library (also called MeSH), EMBASE (known as EMTREE) and PsycINFO (Thesaurus of Psychological Index Terms).

Saving your searches

Any search that one has performed can be saved by using the ‘Send to’ option and can be saved as a simple word file [ Figure 5 ]. Alternatively, the ‘Save Search’ button (just below the search box) can be used. However, it is essential to set up an NCBI account and log in to NCBI for this. One can even choose to have E-mail updates of new articles in the topic of interest.

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g008.jpg

Saving PubMed searches. A simple option is to click on the dropdown box next to ‘Send to’ option and then choose among the options. It can be saved as a text or word file by choosing ‘File’ option. Another option is the “Save search” option below the search box but this will require logging into your National Center for Biotechnology Information account. This however allows you to set up alerts for E-mail updates for new articles

Single citation matcher

This is another important tool that helps to find the genuine original source of a particular research work (when few details are known about the title/author/publication date/place/journal) and cite the reference in the most correct manner [ Figure 6 ].

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g009.jpg

Single citation matcher: Click on “Single citation matcher” on PubMed Home page. Type available details of the required reference in the boxes to get the required citation

Full text articles

In any search clicking on the link “free full text” (if present) gives you free access to the article. In some instances, though the published article may not be available free, the author manuscript may be available free of charge. Furthermore, PubMed Central articles are available free of charge.

Managing filters

Filters can be used to refine a search according to type of article required or subjects of research. One can specify the type of article required such as clinical trial, reviews, free full text; these options are available on a typical search results page. Further specialized filters are available under “manage filters:” e.g., articles confined to certain age groups (properties option), “Links” to other databases, article specific to particular journals, etc. However, one needs to have an NCBI account and log in to access this option [ Figure 7 ].

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g010.jpg

Managing filters. Simple filters are available on the ‘search results’ page. One can choose type of article, e.g., clinical trial, reviews etc. Further options are available in the “Manage filters” option, but this requires logging into National Center for Biotechnology Information account

The Cochrane library

Although reviews are available in PubMed, for systematic reviews and meta-analysis, Cochrane library is a much better resource. The Cochrane library is a collection of full length systematic reviews, which can be accessed for free in India, thanks to Indian Council of Medical Research renewing the license up to 2016, benefitting users all over India. It is immensely helpful in finding detailed high quality research work done in a particular field/topic [ Figure 8 ].

An external file that holds a picture, illustration, etc.
Object name is IJSTD-35-85-g011.jpg

Cochrane library is a useful resource for reliable, systematic reviews. One can choose the type of reviews required, including trials

An important tool that must be used while searching for research work is screening. Screening helps to improve the accuracy of search results. It is of two types: (1) Practical: To identify a broad range of potentially useful studies. Examples: Date of publication (last 5 years only; gives you most recent updates), participants or subjects (humans above 18 years), publication language (English only) (2) methodological: To identify best available studies (for example, excluding studies not involving control group or studies with only randomized control trials).

Selecting the right quality of literature is the key to successful research literature review. The quality can be estimated by what is known as “The Evidence Pyramid.” The level of evidence of references obtained from the aforementioned search tools are depicted in Figure 9 . Systematic reviews obtained from Cochrane library constitute level 1 evidence.

Thus, a systematic literature review can help not only in setting up the basis of a good research with optimal use of available information, but also in practice of evidence-based medicine.

How can I do a literature review efficiently?

For a new project I want to compile a literature review to determine the state of the art and possible approaches to start with.

Last time I adhered to the following scheme, but it felt very inefficient.

Search scholar.google with relevant keywords. (3-20 papers)
Read this first set of papers and look for main publications most of these papers link to.
Use scholar and webofknowledge to collect all papers, which cite the main publications. (30-200 papers)
Go through all the papers ordered by assumed importance or newness and note used methods, results, strengths and weaknesses in a spreadsheet till running out of time or motivation.

What system do you have to do literature review and what would you recommend me?

After posting my question I found Am I reading enough of the scientific literature? Should I read for breadth or depth? which talks, as I see it, more about how to read scientific publications.

I am more interested in advice on how to make sure one has found all the important publications and how to prioritize one's reading list. One advice I got some time ago was to start with new publications fist and then to work yourself back in time. Is this a good advice? How do you do it?

If you know that the relevant literature is mostly in one community, then the approach you've described works fairly well. It may be "inefficient" if there are lots of related papers, but (to use computer science jargon), it's efficient in the size of the output :)

I have found that finding a recent survey helps a lot, because it taxonomizes the literature and provides many backward pointers (as well as forward pointers via papers that cite it).

But ultimately, the best test is if you start coming across the same papers in references over and over again. At that point you can feel a little more confident that you're converging.

Some specific tips:

Look carefully at how papers are cited. That provides clues on how to prioritize your searching.
Learn how to skim a paper really quickly to see its main contribution, which will indicate whether it merits further interest.
If certain researchers keep popping up, go to their websites to see if other papers might be relevant (or if they have a review article that Google search didn't reveal)
Look at venues where papers are typically getting published, and look at recent issues of those journals/conferences to see if you've missed something.

Apart from that, going across communities is trickier, and often requires some luck, or the right keywords. Again, some knowledge of the researchers in the area helps: odds are that if the topic spans disciplines, at least some of the researchers involved also span disciplines and can point (via their work) to new paths to explore (see the above note about conferences)

More of a tip than a full answer but worth adding non-the-less: try starting off by reading 'review articles' rather than 'papers of original research'. The advantages of doing this are

They provide an historical overview in most cases, useful for getting context
They are more accessible (in terms of readability)
They are longer, containing more information, with more thorough explanations
They tend to be less biased

How To Skim Read Journal Articles

Fast-Track Your Literature Review By Focusing On Three Sections

By: Derek Jansen (MBA) | May 2020

How to read scientific journal articles quickly and efficiently.

If you’ve just started your literature review process, you’re probably sitting on a pile of scientific journal articles and research papers that are (1) lengthy and (2) written in very dense , academic language that is difficult to digest (at the best of times). It’s intimidating, for sure – and you’re probably wondering how on earth you’re going to get through it all.

You might be asking yourself some of these questions:

Do I need to read every journal article to make sure I cover everything?
Do I need to read every section of each article to understand it?
If not, which sections should I focus on?

First things first, relax (I can feel your tension!). In this post, I’m going answer these questions and explain how to approach your review of the literature the smart way , so that you focus only on the most relevant literature and don’t waste time on low-value activities.

So, grab a nice hot cup of coffee (or tea, or whatever – just no beers) and let’s take a look at those questions, one at a time.

Question 1:

Do i need to read every journal article on my topic when doing my literature review.

The good news is that you don’t need to read every single journal article on your topic. Doing so would just be a waste of your time, as you’re generally looking to understand the current state of the literature – not the full history of it.

But… and this is an important but. You do need to read quite a bit to make sure that you have a comprehensive view of the current state of the literature (and of knowledge) in your area of research.

Quality trumps quantity when it comes to reviewing the literature. In other words, you need to focus on reading the journal articles that are most cited (i.e. that other academics have referenced) in relation to your topic keyword(s). You should focus on articles that are recent, relevant and well cited .

But how do I know if an article is well cited?

Thankfully, you can check the number of citations for any article really easily using Google Scholar . Just enter the article title in Google Scholar and it will show you how many citations it has – here’s an example:

How to read journal articles quickly and efficiently

In fact, Google Scholar is a great way to find the key journal articles for any keyword (topic) in general, so chances are you’ll be using this to find your journal articles in the first place. Therefore, be sure to keep an eye on citation count while you’re sourcing articles. It would also be smart to dedicate a column to it in your literature review catalogue (you can download one for free here ) so that you can quickly filter and sort by citation count.

A quick caveat – citation count is not a perfect metric for the quality of a journal article (unfortunately there is no unicorn metric that indicates quality). While its usually a good indicator of how popular an article is, it doesn’t mean the findings of the article are perfect (remember, the Kardashians are popular too – enough said). To the contrary, it could indicate that there’s a lot of controversy regarding the findings (sounds like the Kardashians again).

So, long story short – don’t be conned by citation count alone. Be sure to also pay attention the to quality of the journal each article is published in (you can check journal rank here ), and pay attention to what other articles say about any given popular article.

Need a helping hand?

Question 2:

Do i need to read the full journal journal article when doing my literature review.

Some more good news – no, you don’t need to read every single word in each journal article you review as part of your literature review. When you’re just starting your literature review, you need to get a big picture view of what each journal article is saying (in other words, the key questions and findings). Generally you can get a good feel for this by reading a few key sections in each article (we’ll get to these next).

That said (ah, there had to be a catch, right?), as you refine your literature review and establish more of a focus, you’ll need to dive deeper into the most important articles. Some articles will be central to your research – but you probably still don’t need to read them from first page to the last.

Question 3:

Which sections of each journal article should i read.

To get a big-picture view of what any article is all about, there are three sections that are very useful. These three sections generally explain both what the article is about (i.e. what questions they were trying to answer) and what the findings were (i.e. what their answers were). This is exactly what you’re looking for, so these three sections provide a great way for you to save time during your literature review.

So, let’s take a look at the three sections:

1 – The abstract (or executive summary)

The abstract (which is located right up front) provides a high-level overview of what the article is about. This is giving you the first little taste of the soup , so to speak. Generally, it will discuss what the research objectives were was and why they were important. This will give you a clear indication of how relevant the article is to your specific research, so pay close attention.

Sometimes the abstract will also discuss the findings of the article (much like a thesis abstract ), but this is not always the case (yeah, the abstract can be such a tease sometimes). If it does, it’s a bonus. But even so, you should still read the other sections, as the abstract only provides a very high-level view, and can miss out on specific nuances of the research.

2 – The introduction section

The introduction section will go into more detail about the topic being investigated and why this is important for the field of research. This will help you understand a bit more detail about what exactly they were investigating and in what context . Context is really important, so pay close attention to that.

For example, they might be investigating your exact topic, but in a country other than your own, or a different industry. In that case, you’d know that you need to pay very close attention to exactly how they undertook their research.

So, make sure you pay close attention to the introduction chapter to fully understand the focus of the research and the context in which it took place . Both will be important when it comes to writing your literature review, as you’ll need to use this information to build your arguments.

3 – The conclusion

While the introduction section tells you what the high-level questions the researchers asked, the conclusion section tells you what answers they found . This provides you with something of a shortcut to grasping the gist of the article, without reading all the dull and dry detail – yeah, it’s a little cheeky, I know. Of course, the conclusion is not going to highlight every nuance of the analysis findings, so if the article is highly relevant to your research, you should make sure to also pay close attention to the analysis findings section.

In addition to the findings of the research, the conclusion section will generally also highlight areas that require further research . In other words, they’ll outline areas that genuinely require further academic investigation (aka research gaps ). This is a gold mine for refining your topic into something highly original and well-rooted in the existing literature – just make sure that the article is recent, or someone else may have already exploited the research gap. If you’re still looking to identify a research topic, be sure to check out our video covering that here .

By reviewing these three sections of each article, you’ll save yourself a lot of time, while still getting a good understanding of what each article is saying. Keep in mind that as your literature review progresses, you focus will narrow and you’ll develop a set of core highly relevant articles, which you should sink your teeth into more deeply.

To fast-track your reading, always start by working through the abstract, the introduction section and the conclusion section.

Let’s Recap

In this post, we looked at how to read academic journal articles quickly and efficiently, to save you many hours of pain while undertaking your literature review.

The key takeaways to remember are:

You don’t need to read every single journal article covering your topic – focus on the most popular, authoritative and recent ones
You don’t need to read every word of every article. To start, you just need to get a high-level understanding of the literature, which you can get by focusing on three key areas in each journal article.
The three sections of each journal article to review are the abstract , the introduction and the conclusion .
Once you’ve narrowed down your focus and have a core set of highly relevant, highly authoritative articles, you can dive deeper into them, paying closer attention to the methodology and analysis findings.

And there you have it – now go on and hammer through that pile of articles at warp speed. While you’re at it, why not also check out our other posts and videos covering research topic ideation , dissertation and thesis proposal , literature review , methodology , analysis and more.

Psst… there’s more!

Thank for your great help!

Hi Derek, i am busy with my research literature. I submited my 1st draft but it was way irrelevant as per comments made by my supervisor… i gave myself time to find out where i diverted until i lesson to some of your videos. As we speak now, i am starting following the guidelines and i feel confident that i am on the right track now. Thanks a lot my brother

You’re most welcome 🙂

I can’t explain my mood when I realised I had to study more than 40 articles about my study field. It was indeed a game-changer. Thank you very much, Derek. Also, Kardashian was the best example that can be used for this situation :)))

Thank you for posting this. It truly takes a load off! I’m new to Doctoral research and peer review study and “Overwhelmed” doesn’t quite sum up how I felt. This is a tremendous help!

Thank you for the advice. Question, how do one keep count of all the articles considered from starting point to narrowed down. Manually, or is there another way?
