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.

How To Write A Literature Review - A Complete Guide
Table of Contents
A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.
Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.
Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.
In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.
What is a literature review?
A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.
Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:
“A literature review surveys 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 explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”
Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.
A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.
As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.
What is the purpose of a literature review?
A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.
What is the importance of a literature review?
The literature review is a critical part of research papers because it helps you:
- Gain an in-depth understanding of your research question and the surrounding area
- Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
- Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
- Elaborate on the validity and suitability of your theoretical framework and research methodology
- Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
- Convey to readers how your study is different or how it contributes to the research area
How long should a literature review be?
Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.
Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.
Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.
What are the different types of literature reviews?
All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.
Here are the different types of literature reviews:
Argumentative review
It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.
Integrative review
It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.
Methodological review
This approach delves into the ''how'' and the ''what" of the research question — you cannot look at the outcome in isolation; you should also review the methodology used.
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 collect, report, and analyze data from the studies included in the review.
Meta-analysis review
Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.
Historical review
Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon 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 identify future research's likely directions.
Theoretical Review
This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.
Scoping Review
The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.
State-of-the-Art Review
The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.
Can you use the first person in a literature review?
When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."
Do you need an abstract for a literature review?
Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:
- The research topic and your motivation behind selecting it
- A one-sentence thesis statement
- An explanation of the kinds of literature featured in the review
- Summary of what you've learned
- Conclusions you drew from the literature you reviewed
- Potential implications and future scope for research
Here's an example of the abstract of a literature review
Is a literature review written in the past tense?
Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.
How many sources for a literature review?
There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.
The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.
Quick tips on how to write a literature review
To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.
You need to follow the below-mentioned steps, to write a literature review:
- Outline the purpose behind the literature review
- Search relevant literature
- Examine and assess the relevant resources
- Discover connections by drawing deep insights from the resources
- Structure planning to write a good literature review
1. Outline and identify the purpose of a literature review
As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:
- How many sources do I need to include?
- What kind of sources should I analyze?
- How much should I critically evaluate each source?
- Should I summarize, synthesize or offer a critique of the sources?
- Do I need to include any background information or definitions?
Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.
2. Search relevant literature
Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.
You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:
- Google Scholar
- Microsoft Academic
- Science.gov
Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.
Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.
3. Examine and assess the sources
It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.
While analyzing the sources, you should look to find out answers to questions like:
- What question or problem has the author been describing and debating?
- What is the definition of critical aspects?
- How well the theories, approach, and methodology have been explained?
- Whether the research theory used some conventional or new innovative approach?
- How relevant are the key findings of the work?
- In what ways does it relate to other sources on the same topic?
- What challenges does this research paper pose to the existing theory
- What are the possible contributions or benefits it adds to the subject domain?
Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.
Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.
4. Discover connections
At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.
A few aspects that you should be aware of while writing a literature review include:
- Rise to prominence: Theories and methods that have gained reputation and supporters over time.
- Constant scrutiny: Concepts or theories that repeatedly went under examination.
- Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
- Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
- Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends
Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.
5. Structure planning to write a good literature review
There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.
Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.
Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

• No detailed explanation of the procedure to discover and identify an appropriate literature review.
7. What are the 5 C's of writing literature review?
• Cite - the sources you utilized and referenced in your research.
• Compare - existing arguments, hypotheses, methodologies, and conclusions found in the knowledge base.
• Contrast - the arguments, topics, methodologies, approaches, and disputes that may be found in the literature.
• Critique - the literature and describe the ideas and opinions you find more convincing and why.
• Connect - the various studies you reviewed in your research.
8. How many sources should a literature review have?
When it is just a chapter, sources should equal the total number of pages in your article's body. if it is a self-contained paper in itself, you need at least three times as many sources as there are pages in your work.
9. Can literature review have diagrams?
• To represent an abstract idea or concept
• To explain the steps of a process or procedure
• To help readers understand the relationships between different concepts
10. How old should sources be in a literature review?
Sources for a literature review should be as current as possible or not older than ten years. The only exception to this rule is if you are reviewing a historical topic and need to use older sources.
11. What are the types of literature review?
• Argumentative review
• Integrative review
• Methodological review
• Systematic review
• Meta-analysis review
• Historical review
• Theoretical review
• Scoping review
• State-of-the-Art review
12. Is a literature review mandatory?
Yes. Literature review is a mandatory part of any research project. It is a critical step in the process that allows you to establish the scope of your research, and provide a background for the rest of your work.

Mastering Verb Tenses in Literature Reviews
In this blog, we will see what tense you should use in the literature review section of your research paper. We will look at some examples of literature review excerpts from published research papers and understand the tenses used in them.
1. Which Tense to Use?
You may have to use multiple tenses in your literature review depending on what you are saying. The present tense is generally used in statements to introduce the literature review, and the past tense is typically used when you are talking about specific papers. The following table summarizes different types of statements you might typically include in your literature review and the corresponding tenses you should use.
(2003) | ||
2. Usage Example #1
In the first statement, we make a general statement about the topic by saying that this topic has been studied extensively in the literature, and therefore we have used the present tense. In the second sentence, we say that although there has been a lot of research on this topic, it is still relevant today and therefore we have used the present perfect tense.
✔ Example of simple present & present perfect tense use This is widely reported and extensively explored in the literature. This has been of interest for a considerable period, ranging from the early 90s. _ Broad summary (Simple Present) _ Ongoing situation (Present Perfect)
3. Usage Example #2
In the first statement, we begin the literature review by saying that there are many techniques available in the literature to combat weight gain. This statement is only a general summary of previous research on this topic. So we used the present perfect tense. Then, when we then talk about individual works from the literature, we present their results in the past tense.
✔ Example of present perfect & past tense use A number of solutions have been proposed to deal with the problem of weight gain and obesity. He simplest approach was proposed by Lee et al. (2003) which involves fasting. Wang et al. (2010) proposed an alternative solution of using an intragastric balloon. _ Broad summary (Present Perfect) _ Specific papers from past (Past Tense)
4. Usage Example #3
In the following example, in the first sentence we are talking about a collective finding that is generally accepted in the field, and therefore we have used the present perfect tense. In the second statement, we are talking about a finding from a specific work conducted in the past and have therefore used the past tense.
✔ Example of present perfect & past tense use It has been shown that there is a direct correlation between social media and children’s mental health[1-10]. Recently, Elan et al. [11] showed that these findings also applies to teenagers and older population. _ Accepted findings (Present Perfect) _ Specific paper from past (Past Tense)
5. Usage Example #4
In the example below, we talk about past research papers and that’s why we have used the past tense.
✔ Example of past tense use In the initial work presented by Kim et al. (2004), they showed that there is a direct link between Vitamin C and obesity. Smith et al. (2006) replicated this finding in a much larger study. Recently, it was pointed out by Young et al. (2010) that Vitamin C is also related to many other diseases. _ Specific papers from past (Past Tense)

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 Literature Review
Start drafting.
It’s time to start drafting your paper. Follow the structure from your outline and start filling in the missing parts. Get out your notes and remind yourself of the sources you plan to talk about. You don’t have to write your paper from beginning to end in order–you can go to the parts that feel the easiest and start there. Here are some places you can start:
Bullet-Point Draft
With a Bullet-Point draft you take the ideas you’ve been outlining and fill them in with more details but only in bullet-point form. The beauty of bullet points is that they keep you from getting caught up in the language and style and allow you to focus simply on your main points. You can smooth out the sentences and transitions later, but for now, just get your ideas on the page.
Write the Introduction
Another way to get started is to write the Introduction. You already have a thesis statement, so now you can start introducing your topic and its importance, setting up your literature review.
Write a Body Paragraph
Or a third place to start is to jump into writing a body paragraph that synthesizes your sources. Use your notes and outline, and choose one set to talk about in paragraph form.
Don’t think too hard about getting things perfect when you’re drafting–that’s what revision is for. Just focus on getting started. If you get stuck, do some brainstorming activities to get your creative juices flowing. Once you have something written, I suggest seeking feedback to make sure you’re going in the right direction. In fact, I recommend getting as much feedback as possible along the way.
As you create a draft, try to incorporate several sources into each paragraph to be sure that you’re synthesizing and not just summarizing or listing without making connections. Your color-coded notes can help you be sure that you’re synthesizing.
Add Metacommentary
Metacommentary is the key to synthesis. Metacommentary (aka metadiscourse) is a type of commentary that guides your reader and helps them interpret the sources and evidence you’re presenting. Think of it as really powerful transitions.
Transition words act like signposts–they guide your reader through your points. They can also glue your ideas together so they feel more cohesive. Beware that transitions can definitely be overdone, but most students in general could use more transitions in their papers rather than fewer.
You might think you can just stop at transition words, but metacommentary is much more than just sprinkling some “therefores” and “howevers” throughout your paper–metacommentary actually takes your synthesis to the next level. What do you comment on? You can either interpret why a source is important, highlight its significance, or connect it with other sources. This is your chance to point out the answers to the four questions you looked for in your note-taking:
What do researchers agree and disagree about?
How are researchers narrowing or changing their focus to create new information?
What are each study’s limitations and strengths?
What’s the next step in research—what should be studied in the future? (The research gap)
You can think of metacommentary as a sandwich with your name on it. If my student’s name were Alisa, here’s what and Alisa sandwich would look like:
ALISA-SOURCE-ALISA
First, Alisa starts with a claim about what’s happening in the field or about a particular subsection or focus of the field. This could serve as a topic sentence for a paragraph, for example.
Second, she sets up the source with guiding language like transitions and references to her past points or sources.
Third, she writes about the source itself and summarizes pertinent information.
Lastly, Alisa comments on the source and/or connects it to her main point or to next source.
This type of sandwich can occur several times in a paragraph as you synthesize your sources. Here’s a sample paragraph from Chris, a Public Health student, who wrote a paper called “The Causes of a Behavioral Pandemic: Screen-time Addiction and Consequent Depression Among Adolescents.” I’ve bolded the metacommentary Chris included to guide his readers and to connect his points.
Even though there have been far fewer studies on adolescents than adults , adolescent studies have consistently shown that those who are more physically active experience less depressive and associated symptoms, as well as a greater overall state of well-being (Kremer, 2014). These studies have also shown that low levels of vigorous exercise in youth can independently cause depressive symptoms. One longitudinal study revealed that over 30% of children who participate in high levels of screen-time use experience moderate to high levels of depressive symptoms (Kremer, 2014). Additionally, another study of children in the United States demonstrated that those who participated on a sports team were less likely to exceed recommended screen-time limits established by the US Department of Health. This study also demonstrated that as the number of total physical activity sessions increased among youth, both during free time and at organized events, children were less likely to exceed recommended screen-time limits (Carlson, 2010). In this study, children who were more physically active consistently showed lower rates of depression and other emotional disorders. Therefore, evidence across multiple studies suggests that participating in screen-time activity may not be the direct cause of depressive symptoms, but rather the sedentary lifestyle and lack physical activity it causes among youth. With this recent evidence, experts are beginning to search for ways to replace screen-time participation of adolescents with physical activities.
Note how the last few sentences of this paragraph consist entirely of metacommentary–points that connect to the bigger picture of Chris’s literature review. Also notice how Chris uses transition words and phrases to glue his points together so it doesn’t come out of the blue when he brings up a new study. Also, Chris discusses more than one study in this paragraph, demonstrating his ability to synthesize and not just summarize. Without the metacommentary, it would be much harder to see the connections between the studies and how they fit into the bigger picture. Finally, Chris indicates the implications of these studies and points to what researchers are doing next . This has a duel purpose of reminding readers why this topic is important as well as indicating where he will go in his next paragraph (about physical activities). Metacommentary is powerful!
Metacommentary takes practice, but you can do it! And it will not only make your points stronger, it will make it easier for your audience to read and understand–which should always be your goal.
If You Get Stuck
Literature reviews can be hard. If you get stuck, I have a little trick I tell my students. For your first draft, try starting every sentence with “Researchers . . .” I know this seems formulaic, but if you can keep your focus on what particular researchers did or what they agree or disagree on, you’ll avoid the most common pitfalls of literature reviews: sounding like a typical argumentative research paper. If your focus is always on what researchers are doing or what they’ve found, then at the very least you’ll stay in the realm of the literature review genre. Later you can go back through and change up your sentence structure, but I’ve found that this is an easy way for students to get through a first draft.
A Word on Verb Tense
Tense | Reference | Example |
---|---|---|
Past Tense | A Single Study or Event | McFly (1989) investigated the usefulness of hoverboards in a chase. |
Present Tense | Generally Accepted Knowledge of the Field | One of the most promising areas of hoverboard technology is the use of electromagnets (Allain, 2015). |
Present Perfect Tense | An Area of Inquiry | The usefulness of skateboards in a chase has been widely researched (McFly, 1985; McFly, 1989; McFly, 1990). |
The Real Last Step: Revise (and Revise and Revise)
Fantastic BYU Family Science professor Julie Haupt offers the following suggestions for doing four purposeful revisions–two global and two local.
GLOBAL REVISION–The Forest
Level 1: structural review (global).
Purpose: The structural review examines the document as a whole to see if all requirements are met and the document’s organization is sound.
Meet Assignment Requirements. Ask yourself if your paper meets all the requirements of the assignment? Look at your structure and make sure you have all necessary sections such as the following:
- Introduction (with Thesis Statement and/or Organizing Statement)
Body with Headings
Conclusion/Discussion
Include a Thesis and an Organizing Statement. Does the current version of the thesis statement match the tone, scope, and organization of the body text? Does an organizing statement after the thesis introduce the major topics and the order they will appear in the body (e.g., “This review will first discuss . . . then . . . and finally . . .)
Use Headings. Is the body text subdivided in a logical way with evidence-based information located in appropriate sections? Are the major sections roughly symmetrical (in terms of length)? Are the headings brief, yet descriptive? If subheadings are used, does the major section contain at least two? Are all levels of headings separated by text?
Level 2 (Global): Paragraph/Logic Review
Purpose: The Paragraph/Logic Review is designed to review each paragraph for cohesion and compliance to the CEC (Claim/Evidence/Commentary) format.
Sequence Paragraphs Effectively. When reading only the first sentence of each paragraph, does the logical pattern of the paper emerge? Do the claims made in these topic sentences coordinate well with the thesis of the paper?
Check Topic Sentences and Cohesion. Does the topic sentence or claim provide an effective overview of the information that is located in the paragraph? Is the claim supported by several points of synthesized evidence, rather than a single study? Does each paragraph seem well directed and cohesive? Do the sentences build one upon another within the paragraph in a logical way?
Evaluate Paragraph Length. Are any paragraphs too long (longer than approximately ½ page)? Are any paragraphs too short (approximately three sentences or less)? Do paragraphs transition well from one to the next and use transitional words to connect ideas?
LOCAL REVISION–The Tree
Level 3 (local): apa formatting review.
Purpose: The APA Formatting Review is designed to make sure all APA conventions are explicitly followed to help the paper reflect a high level of professionalism.
Check Document Formatting. Do the body text and reference page appear in the correct page formatting as required? (Use the APA Manual if you have questions.)
Examine the Reference List Closely. Are all references in the reference list ordered alphabetically? Is the reference list double spaced entirely (with no extra gaps between paragraphs)? Are all references (e.g., journal articles, internet resources, or books) listed in the correct format? Is every reference on the reference list cited at least once in the body and does each in-text citation have a corresponding reference in the reference list?
Make a Final Check of the In-Text Citations. Is all information properly cited with an in-text citation when needed? Do all in-text citations include the year next to the author(s)? When more than one citation is listed within parentheses are they separated by semi-colons and ordered alphabetically by first author’s last name? If included in parentheses, do studies with multiple authors use ampersands (“&” rather than the word “and”) before listing the last author?
Level 4 (Local): Finishing Review
Purpose: The Finishing Review is an opportunity to look closely at sentence construction, language, hedging , and grammar/punctuation.
Review Phrasing with a Read-Aloud Session. Since having to read a sentence twice to get its meaning or “tripping over” phrasing can be an indication of awkward construction, are all sentences easily read aloud? Are any sentences so long that they have become difficult to comprehend, but could be split without changing the meaning?
Use Non-Biased, Non-Absolute Language. Do all references to people comply with the “people first” designation and avoid inappropriate uses of terms for various groups? Are the findings and summary statements in the review properly “ Hedged ”?
Check Punctuation and Grammar. Are all commas, semicolons, colons, hyphens, and other punctuation used correctly throughout the document (including the reference page)? Are common grammar mistakes, such as parallelism, subject-verb agreement, incorrect misuse of pronouns, and other grammatical issues corrected?

“You will use a range of tenses depending on what you are writing about . ” Elizabeth M Fisher, Richard C Thompson, and Daniel Holtom, Enjoy Writing Your Science Thesis Or Dissertation!
Tenses can be tricky to master. Even well respected journals differ in the guidance they give their authors for their use. However, their are some general conventions about what tenses are used in different parts of the report/dissertation. This page gives some advice on standard practice.
What tenses will you use?
There are exceptions however, most notably in the literature review where you will use a mixture of past , present and present perfect tenses (don't worry, that is explained below), when discussing the implications of your findings when the present tense is appropriate and in the recommendations where you are likely to use the future tense.
The tenses used as standard practice in each of these sections of your report are given and explained below.
In your abstract
You have some leeway with tense use in your abstract and guidance does vary which can sometimes be confusing. We recommend the following:
Describing the current situation and reason for your study
Mostly use the present tense, i.e. "This is the current state of affairs and this is why this study is needed."
Occasionally, you may find the need to use something called the present perfect tense when you are describing things that happened in the past but are still relevant. The present perfect tense uses have/has and then the past participle of the verb i.e. Previous research on this topic has focused on...
Describing the aims of your study
Here you have a choice. It is perfectly acceptable to use either the present or past tense, i.e. "This study aims to..." or "This study aimed to..."
Describing your methodology
Use the past tense to describe what you did, i.e. "A qualitative approach was used." "A survey was undertaken to ...". "The blood sample was analysed by..."
Describing your findings
Use the past tense to describe what you found as it is specific to your study, i.e. "The results showed that...", "The analysis indicated that..."
Suggesting the implications of your study
Use the present tense as even though your study took place in the past, your implications remain relevant in the present, i.e. Results revealed x which indicates that..."
Example abstract
An example abstract with reasoning for the tenses chosen can be found at the bottom of this excellent blog post:
Using the Present Tense and Past Tense When Writing an Abstract
In your methodology
The methodology is one of the easiest sections when it comes to tenses as you are explaining to your reader what you did. This is therefore almost exclusively written in the past tense.
Blood specimens were frozen at -80 o C.
A survey was designed using the Jisc Surveys tool.
Participants were purposefully selected.
The following search strategy was used to search the literature:
Very occasionally you may use the present tense if you are justifying a decision you have taken (as the justification is still valid, not just at the time you made the decision). For example:
Purposeful sampling was used to ensure that a range of views were included. This sampling method maximises efficiency and validity as it identifies information-rich cases and ... (Morse & Niehaus, 2009).
In your discussion/conclusion
This will primarily be written in the present tense as you are generally discussing or making conclusions about the relevance of your findings at the present time. So you may write:
The findings of this research suggest that.../are potentially important because.../could open a new avenue for further research...
There will also be times when you use the past tense , especially when referring to part of your own research or previous published research research - but this is usually followed by something in the present tense to indicate the current relevance or the future tense to indicate possible future directions:
Analysis of the survey results found most respondents were not concerned with the processes, just the outcome. This suggests that managers should focus on...
These findings mirrored those of Cheung (2020), who also found that ESL pupils failed to understand some basic yet fundamental instructions. Addressing this will help ensure...
In your introduction
The introduction generally introduces what is in the rest of your document as is therefore describing the present situation and so uses the present tense :
Chapter 3 describes the research methodology.
Depending on your discipline, your introduction may also review the literature so please also see that section below.
In your literature review
The findings of some literature may only be applicable in the specific circumstances that the research was undertaken and so need grounding to that study. Conversely, the findings of other literature may now be accepted as established knowledge. Also, you may consider the findings of older literature to be still relevant and relatively recent literature be already superseded. The tenses you write in will help to indicate a lot of this to the reader. In other words, you will use a mix of tenses in your review depending on what you are implying.
Findings only applicable in the specific circumstances
Use the past tense . For example:
In an early study, Sharkey et al. (1991) found that isoprene emissions were doubled in leaves on sunnier sides of oak and aspen trees.
Using the past tense indicates that you are not implying that isoprene emissions are always doubled on the sunnier side of the trees, just that is what was found in the Sharkey et al. study.
Findings that are still relevant or now established knowledge
Mostly use the present tense , unless the study is not recent and the authors are the subject of the sentence (which you should use very sparingly in a literature review) when you may need to use a mixture of the past and present. For example:
A narrowing of what 'graduateness' represents damages students’ abilities to thrive as they move through what will almost certainly be complex career pathways (Holmes, 2001).
Holmes (2001) argued strongly that a narrowing of what 'graduateness' represents damages students’ abilities to thrive as they move through what will almost certainly be complex career pathways
Both of these imply that you think this is still the case (although it is perhaps more strongly implied in the first example). You may also want to use some academic caution too - such as writing 'may damage' rather than the more definite 'damages'.
Presenting your results
As with your methodology, your results section should be written in the past tense . This indicates that you are accepting that the results are specific to your research. Whilst they may have current implications, that part will not be considered until your discussion/conclusions section(s).
Four main themes were identified from the interview data.
There was a significant change in oxygen levels.
Like with the methodology, you will occasionally switch to present tense to write things like "Table 3.4 shows that ..." but generally, stick to the past tense.
In your recommendations
Not everyone will need to include recommendations and some may have them as part of the conclusions chapter. Recommendations are written in a mixture of the present tense and future tense :
It is recommended that ward layout is adapted, where possible, to provide low-sensory bays for patients with autism. These will still be useable by all patients but...

The 7th edition style manual of the American Psychological Association (APA) provides suggestions on which verb tense is appropriate for various sections of a thesis, major project or journal article:
- Past or present perfect tense: "Literature review (or whenever discussing other researchers' work)" (APA, 2020, p. 118), "method" (APA, 2020, 118), and "description of procedure" (APA, 2020, 118)
- Past tense: "Reporting of results" (APA, 2020, p. 118)
- Present tense: "Discussion of implications of results" (APA, 2020, p. 118) and "presentation of conclusions, limitations, future directions, and so forth" (APA, 2020, p. 118).
As much as possible, try to be consistent with your chosen verb tense within a section "to ensure smooth expression" (APA, 2020, p. 118). If the verb tenses suggested above don't make sense for the purposes of your document, please check with your instructor or academic supervisor to get their recommendation on the best approach for your document.

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.

Use past tense when reporting research (e.g. writing a literature review). One way to think about this is that the research reports about which you are writing have been written in the past: the research is finished and reported. If you are writing a research proposal, the tense you use will help distinguish between your proposed study and the research literature you draw upon. The APA Manual advises that "the past tense is appropriate when expressing an action or a condition that occurred at a specific, definite time in the past, such as when discussing another researcher's work" (APA, 2020, pp. 117-118).

Verb tenses in scientific writing: Which tense should you use?
If you’re fluent in English, using tenses in scientific writing should come naturally to you. You shouldn’t need to flip through a grammar book, ask a freelance editor, or search online for “methods tense” or “literature review tense”.
But verb tenses may start to haunt you if you’re writing an article for a top peer-reviewed journal and you know you have to get every detail right. For example, you may wonder, What tense should be used in methodology sections? Should the introduction or literature review be written in the present tense or past tense?
In this post I’m going to answer these and other questions on verb tenses in scientific writing to make it easier for you to understand which tenses to use in a research paper.
Past or present tense in a cademic writing? It depends.
There’s no consensus on how authors should be using verb tenses in scientific writing. Here is a summary of the main recommendations of academic writing experts on tenses in scientific writing.
Literature review verb tense
For the literature review, most academic editors recommend using the past simple or present perfect when talking about past research.
Use the past simple to discuss what was done in the past (the authors collected, investigated, analyzed, etc.).
Use present perfect to talk about findings from previous studies that are still valid today (the author has shown, has demonstrated, etc.).
If you don’t want to use the past simple or present perfect tense in literature review sections, your other option is the present simple tense. This is the so-called literary present.
Writing the literature review in the present simple tense helps simulate an ongoing academic conversation , to which you’re contributing (“Author et al. (2021) find…, discuss…, examine… imply…”).
In summary, what tense should the introduction be written in?
- Past simple or present perfect tense for past research
- Present simple for general truths or for the entire literature review section
Verb tenses in the methodology and results sections
For the methodology, almost all academic writing resources agree that the past simple tense is the logical choice. You are discussing what you did (collected data, analyzed them, and derived your results)—and all of that happened in the past.
However, you may also need to use the present simple tense to refer to figures and tables.
In summary, what tense should methods be written in?
For the methodology section, use these tenses:
- the past simple tense to explain your methods
- the present simple tense to refer to figures or tables
What tense should a discussion be written in?
Tenses for the discussion are similar to those for the introduction:
- past simple or present perfect tense when referring to what you did (past research)
- present simple for general truths or for interpretations of your data
Verb tenses in the conclusion section
For the conclusion, you may need to use several tenses. Again, when referring to general truths or implications of your results, use the present simple. When referring to what you did, use the past simple or present perfect tense.
Use the simple past when discussing the research you completed and is no longer continuing. Use the present perfect when discussing an action that started in the past and is still happening now, or an action that happens regularly.
So, for the conclusion, use these tenses:
- present simple for things that are true at the time of writing, the conclusions of your study, and its implications
- past simple or present perfect tense for past work
Knowing how to use verb tenses in scientific writing is better than imitating other authors
In scientific writing, using verb tenses inconsistently or unnecessarily shifting tenses means sloppy writing. A poorly written manuscript submitted to a peer-reviewed journal will come back with a long list of revisions—if it’s accepted for publication. Hiring a freelance editor for research papers can help you polish your writing style and improve the likelihood that your manuscript will be accepted the second time.
If you don’t want to hire a freelance editor, you may need to edit your own research paper . Mastering verb tenses in scientific writing will help you make the right choice for each section of your paper.
Try to resist the temptation to imitate others’ writing style. It’s common for new authors to learn academic writing the same way they learned to speak: by imitation. They peruse some articles published in their target journal to see what verb tenses other authors used and then make the same choices.
However, this is not such a great idea, because not all published articles are examples of good writing. You risk imitating an author that didn’t pay much attention to verb tenses in scientific writing, or whose work was edited by someone with little experience.
How to choose the right verb tenses for a research paper
If emulating others’ writing style comes with the risk of picking up bad habits, how do you choose the right verb tense to use in a scholarly paper?
Unfortunately, style guides, academic writing books, and academic editors give conflicting advice. A solution to this problem is to follow the recommendations of your university’s writing center if you’re writing a PhD thesis or dissertation. If, however, you’re writing a research paper for a journal, follow its guidelines.
Some publishers may let you choose any style guide as long as you’re consistent. In that case, go with the style popular in your academic field (for example, APA Style in social sciences).
Example: Verb tenses in APA Style
If you need to follow the APA Style, it has precise instructions on using verb tenses in research papers:
- Introduction and literature review: To talk about previous studies, use the past simple or present perfect; for findings that continue to be true, use the present simple.
- Methodology and results: To talk about your methods or results, use the past simple or present perfect.
- Conclusions: Write the conclusions of your research and implications of your findings in the present simple.
Here are some examples to help you understand how to use verb tenses in APA:
- Past simple tense to discuss past work:
Author A (2017) showed that varied populations display similar patterns, but Author B demonstrated that patterns vary wildly
- Present perfect to discuss findings from previous studies that are still valid today:
Other researchers have described similar processes in other environments
- Present simple to express general truths, facts, or ideas accepted today:
Most researchers agree that our species appeared in Africa
- Present perfect or past simple tense to describe your methods and results:
We have observed no variation in the economic growth rate, but found it depends on several factors
- Present simple tense to describe the conclusions and implications of your study:
Our results indicate a strong correlation between A and B, but we need further research in this area
Use the right tenses in scientific writing for clarity
The goal of using the right verb tenses in scientific writing is clarity. So, whether you follow your instincts, your advisor’s suggestions, an editor’s recommendations, or a style guide, aim at clarity and logic. A well-written manuscript will have a better chance of being accepted for publication. Also, it won’t require several rounds of revision to improve its language, meaning you save time and can focus on your science.

Verb tenses – literature.
This handout is available for download in DOCX format and PDF format .
Use of the correct verb tense allows you to express clearly the time relationships among your ideas. When deciding which verb tense to use, aim for consistency, simplicity, and clarity. Whenever possible, keep verbs in the same tense (consistency), and use either the simple present or the past tense (simplicity). Above all, choose the verb tense that most clearly expresses the idea you want to convey (clarity). In general, use the present tense to describe actions and states of being that are still true in the present; use the past tense to describe actions or states of being that occurred exclusively in the past.
Below are some discipline-specific guidelines for how to use verb tenses effectively in literature and the humanities. For details on tenses in science writing, see handout “Verb Tenses—Science.”
Decribing the Text
Use the present tense to describe fictional events that occur in the text:.
(This use of present tense is referred to as "the historical present.")
- In Milton's Paradise Lost , Satan tempts Eve in the form of a serpent.
- Voltaire's Candide encounters numerous misfortunes throughout his travels.
Use the present perfect tense to describe an event that occurs in the text previous to the principal event you are describing:
- The governess questions the two children because she believes they have seen the ghosts.
- Convinced that Desdemona has been unfaithful to him, Othello strangles her.
Use the past tense when referring to an event occurring before the story begins:
- In the opening scenes of Hamlet , the men are visited by the ghost of Hamlet's father, whom Claudius murdered .
Providing Factual Information
Use the present tense to report your interpretations and the interpretations of other sources:.
- Odysseus represents the archetypal epic hero.
- Flanagan suggests that Satan is the protagonist of Paradise Lost .
Use the past tense to explain historical context or elements of the author's life that occurred exclusively in the past:
- Hemingway drew on his experiences in World War I in constructing the character of Jake Barnes.
Combining Fact and Fiction
When writing about literature, use both present and past tense when combining observations about fictional events from the text (present tense) with factual information (past tense):.
- James Joyce, who grew up in the Catholic faith, draws on church doctrine to illuminate the roots of Stephen Dedalus' guilt.
- In Les Belles Images , Simone de Beauvoir accurately portrays the complexities of a marriage even though she never married in her lifetime.

In which tense should the conclusion line of existing studies be written?
I am bit confused in which tense I should write the conclusion of existing studies in literature review. For example in past tense, I write the methodology and result of a study. Now I want to write
The findings provide a strong technical foundation for ......
Or should I write
The findings provided a strong technical foundation for ......
- publications
- 3 Whichever you choose, make it consistent. I see many papers where they flip between past and present tense repeatedly within one paragraph, I get a bit seasick from that. :) – Cris Luengo Commented Jun 12, 2023 at 20:54
- This might be informative: nature.com/scitable/topicpage/effective-writing-13815989/… . – Krrr Commented Jul 6, 2023 at 7:21

The difference is very slight. If the findings still provide a strong technical foundation, the presence tense would be more accurate. If you use the past, you might be seen to indicate that they once did, but no longer do provide a strong technical foundation, e.g. because the field has moved on to a better analysis.
- If you use the past, you might be seen to indicate that they once did, but no longer do - I think only if the surrounding context suggests this. To me the difference is more about how far in the past it had an effect, and whether this effect came to fruition already or is ongoing. – Kimball Commented Jun 12, 2023 at 23:50
I suggest present tense. Angelika Hofmann ( Scientific Writing and Communication , fifth edition) suggests in 4.4 (Tense) that one should
Use past tense for observations and specific conclusions
Use present tense for general rules and established knowledge
Hofmann expands on the latter:
You should use present tense for general rules, accepted facts, and established knowledge. Thus, results from already published papers should be described in the present tense as published results are generally assumed to be "facts." Similarly, if something is a general rule or fact that is still true in the present, use present tense. If you use past tense for describing results of already published work, you are implying to the reader that you do not consider these results to be "facts" but observations.
In your case, you are reporting on the findings of a study. Those are results that provide a technical foundation for something. That suggests that the results are still true. So you should probably use present tense.
- It's not entirely clear to me what she means by "observations" as opposed to "facts". Maybe she means "talk about what we know in the present, but about what was written in the past". For instance, "In paper X, author showed that..." "In last section, we proved that..." – Stef Commented Jun 13, 2023 at 9:09

How to Write a Review That Stands Out: A Guide for English Learners
Writing an online review is a powerful way to share your experiences and help others make informed decisions.
This guide will help you understand how to write clear and effective reviews that offer valuable insights and help potential customers make decisions.
Things to consider before writing a review
What are you trying to achieve.
Before you start writing, think about what you want to achieve with your review. Are you trying to share a positive or negative experience? Do you want to provide valuable insights to help others? Do you just want to express your feelings?
Your review can influence a business’s online reputation and guide other customers, so be clear about your goal to make sure your review is helpful and effective.
How to format your review
Formatting your review properly is important to make sure it’s clear and easy to read. Start with a brief introduction that summarises your experience. Then, provide specific details about what you liked or didn’t like.
Use paragraphs to separate different points and make sure to proofread your review for any spelling or grammar mistakes. A well-formatted review shows your attention to detail and makes a stronger impact.
Consider your audience
Think about who will be reading your review. Are you addressing the company to provide feedback, or are you writing for other customers to help them make informed decisions?
Shape your language and specific details to suit your audience. For example, if you’re writing a review for other customers to read, focus on how the product or service met your needs and why you would highly recommend it (or not).
If you’re addressing the company, be sure to provide constructive feedback that could lead to improvements.
Types of reviews and how to write them
How to write a book review.
When writing a book review, include specific details about the plot, characters, and writing style. Mention what you liked or disliked and why. Your insights can have a significant impact on other readers.
Book review example sentences:
- “The author’s descriptive writing made the scenes come alive.”
- “I didn’t enjoy the book because it was slow and uneventful.”
- “The plot was engaging and full of unexpected twists, keeping me on the edge of my seat throughout the entire story.”
How to write a movie review
A good movie review should talk about the story, acting, and direction. Share your positive or negative thoughts and provide details. This helps others decide if they want to watch the movie.
Movie review example sentences:
- “The actors delivered outstanding performances.”
- “The direction was sloppy and uninspired, lacking any clear vision or creativity, which made the movie difficult to follow and unenjoyable to watch.”
- “The story was captivating from start to finish.”
How to write a product review
In a product review, describe how the product or service worked for you. Mention any customer service experiences. Be honest and include both pros and cons to give a balanced view. Good reviews are clear and helpful.
Product review example sentences:
- “The product worked perfectly and exceeded my expectations.”
- “I had a terrible experience with customer service, they were very unhelpful.”
- “I would not recommend this product to anyone; it broke after being used once.”
How to write a restaurant review
For a restaurant review, talk about the food, service, and atmosphere. Would you highly recommend the food? How was the customer service from the wait staff? Your review can help guide others looking for a great dining experience.
Restaurant review example sentences:
- “The food was delicious and beautifully presented.”
- “The service was slow and unprofessional.”
- “The atmosphere was noisy and uncomfortable; I would not eat here again.”
How to write a travel review
When writing a travel review, include specific details about the location, accommodation, and activities. Mention what you enjoyed and what could be improved. This helps others plan their trips better.
Travel review example sentences:
- “There were plenty of fun activities to do, and all within walking distance.”
- “I highly recommend this beautiful destination to other travellers.”
- “The hotel was hard to find, with poor signage and confusing directions, and once we finally arrived, it was not worth the effort due to its outdated facilities.”
How to write a customer service review
A customer service review should focus on the quality of service you received. Did the staff respond to your needs? Were they helpful? Customer reviews that highlight good or bad service can influence a company’s online reputation.
Customer service review example sentences:
- “The staff responded quickly and resolved my issue.”
- “Everyone was friendly and went above and beyond to make sure we had a good time.”
- “I’m very disappointed with the service. The staff were unresponsive, and my issue was not resolved despite multiple attempts to get help.”

British Council Online Course – the best course I have ever had
I am happy with the course as it is informative and educative. It has helped me to improve my knowledge of the English language. English is my second language. I’ve become a much more confident speaker of the English language thanks to this course.
I have enjoyed having classes in group as well as doing pre-class tasks on my own. I am happy that our group has had different teachers as we can improve our listening skills while listening to a new teacher and stay more focused on the material of the lesson.

But if you take the citation to mean the paper itself, then the present tense is fine since the paper still exists and does still show... However, advisors can be a bit picky on some such things, so it would be good to ask ...
A literature review requires the same style as any other piece of academic writing. That means no contractions or colloquialisms, concise language, formal tone, and an objective perspective at all times. To distinguish between your analysis and prior scholarly work in the field, use the past tense when discussing the previous research conducted ...
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.

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present ...
The present tense is generally used in statements to introduce the literature review, and the past tense is typically used when you are talking about specific papers. The following table summarizes different types of statements you might typically include in your literature review and the corresponding tenses you should use.
Examples of literature reviews. Step 1 - Search for relevant literature. Step 2 - Evaluate and select sources. Step 3 - Identify themes, debates, and gaps. Step 4 - Outline your literature review's structure. Step 5 - Write your literature review.
The past perfect tense is often constructed by using the word "had" or "have" before the verb (Darling, 2003). Sentences that might appear in a literature review section using the past perfect tense are: The investigator had completed the assessment tool study before she started the controlled research one.
If you're talking about a current attitude or something currently accepted in a field, then use present tense. For example, if you say that you conducted a review of the literature, then that's over and done with, so you should use the past tense. Or if you want to talk about a particular study that was done, then use the past tense, too.
The methodology is one of the easiest sections when it comes to tenses as you are explaining to your reader what you did. This is therefore almost exclusively written in the past tense..

A recent flurry of tweets, seemingly initiated by @thesiswhisperer, discussed the use of tense in literature review.There doesn't seem to be a definitive rule to using either present or past tense (i.e. Smith (1989) argues… vs. Smith (1989) argued… etc.), though switching from one to the other can be problematic and should only be done within grammatical conventions.
Literature review verb tense. For the literature review, most academic editors recommend using the past simple or present perfect when talking about past research. Use the past simple to discuss what was done in the past (the authors collected, investigated, analyzed, etc.). Use present perfect to talk about findings from previous studies that ...
