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 .

Writing a Critical Review of Literature: A Practical Guide for English Graduate Students

Global Language Review

As an integral part of dissertations and theses, research scholars in different disciplines require to write a comprehensive chapter on "literature review" that establishes the conceptual and theoretical foundations of an empirical research study. This, however, poses an intellectual challenge to produce a critical review of the published research on a given topic. Therefore, this paper addresses the students problems of writing the literature review in a thesis or dissertation at the graduate and postgraduate levels. It explains the process and steps of reviewing literature for a thesis chapter. These steps include; a) critical reading and note-taking, b) writing a summary of the reviewed literature, c) organization of literature review, and d) the use of a synthesis matrix. The last part of the paper offers suggestions on how to write critically and make the researcher's voice explicit in the chapter.

Literature review and writing form the basis of every academic research and writing, and it is most significant and indispensable to every academic research work. Its systematic process of writing has, however, been mysterious, complex, messy and boring, especially to inexperienced researchers and postgraduate students. This study explored the mysteries and ease with academic literature, writing and review. The study used secondary source to gather data and for the analysis, and found that academic literature writing and review comprise of different patterns and systems, dependent upon the nature and character of the research, the writing in contexts and its specific objectives; there are different types of literature and writing in academics, and while no one way is universally accepted by all at the same time, different approaches are required for different types of review and writings. The difficulty in understanding, reviewing and writing of literature mainly emanates from failure right from the inception to clearly identify what precisely the reviewer wants and how to go about looking for it in a systematic and comprehensive manner. Reviewing and writing of academic literature is a herculean task and for it to be successful there must be focus, specific objectives, adequate and timely provision and access to relevant materials. With proper understanding, it can be mastered and made easy. The study is essential for academics and post graduate students who must undergo literature review and writing at varying stages, especially at critical, stipulated and limited times.

The importance of literature review in academic writing of different categories, levels, and purposes cannot be overemphasized. The literature review establishes both the relevance and justifies why new research is relevant. It is through a literature review that a gap would be established, and which the new research would fix. Once the literature review sits properly in the research work, the objectives/research questions naturally fall into their proper perspective. Invariably, other chapters of the research work would be impacted as well. In most instances, scanning through literature also provides you with the need and justification for your research and may also well leave a hint for further research. Literature review in most instances exposes a researcher to the right methodology to use. The literature review is the nucleus of a research work that might when gotten right spotlights a work and can as well derail a research work when done wrongly. This paper seeks to unveil the practical guides to writing a literature review, from purpose, and components to tips. It follows through the exposition of secondary literature. It exposes the challenges in writing a literature review and at the same time recommended tips that when followed will impact the writing of the literature review.

The literature is a multiplicity of voices. With each voice agendas emerge. Each text is itself a framing of voices and their agendas, shaped to present a debate slanted towards a conclusion. Within that debate can often be detected the friends, the strangers, the guests, the hosts and the enemies that are entertained by the writer. So, there is a problem. It is that whilst acts of framing bring and impose order, those very processes of ordering and categorisation select and edit so that some things are chosen to be foregrounded, others to be background and yet others to be excluded. In the writing task, agenda setting and framing pin possibilities and options down to what is regarded as 'realistic', 'plausible', 'do-able', 'true'. However, there has to be a moment when the literature appears like the vertigo experienced over a sheer and endless drop. Engagement with the literature is the essential step in widening out, indeed seeing the limitless possibilities for open debate with a public extending over centuries, even millennia. Making a voice map of the public space of debate is a way of trying to locate what is at stake in adopting a given way of framing the world and its agendas. Getting a sense of the historical development of major debates, discovering the tributaries, the dead-ends, the forgotten, the overlooked is all a part of the gradual sense of knowing where you are, where you stand, in relation to others. In particular, who claims to know what and why? What kinds of arguments are being made, and why? What are the assumptions at the back of explanations and theories? What happens if the assumptions are challenged or changed? From a review of the literature it is possible to sketch and fill out the details of the problematic, that is, the knot of problems, issues, concerns, interests that each of the voices in the literature have historically addressed. In determining how they address their chosen problems, the outlines of their methodologies can be formulated. Then it is a question of what is at stake expressed by each voice in the choices they make in exploring, examining and forming their conclusions using their chosen methodologies in relation to the problems they address. Which voices have they included in their own reviews of the debates, which have they excluded and why? By asking such questions as these a literature review then can be designed specifically to increase the power of a given argument, set of findings, recommendations and conclusions that have implications for action.

Literature review or research synthesis is an essential component in research field. Novice and student researchers usually take it as a required burden in research, and present haphazardly under sub-topics in research. There is the problem of application and correlating LR with their studies. The main purpose of this paper is to present introduction of LR/research synthesis, its functions and methods in research. LR/research synthesis consists of searching relevant literature, discussing the findings and evidence, correlating the individual studies, interpreting critically, and synthesizing them to build an argument for future research. It is a review article based on qualitative research, but not based on primary data. This paper contributes to answer the questions of writing a LR or synthesis paper, and becomes a useful reference material to novice and student researchers of higher education.

Literature review and writing form the basis of research to which it is indispensable. Its systematic process however, remains mysterious, complex and problematic especially to postgraduate students most of whom undertake research for the first time at graduate level. This paper explored the challenges, strengths and mysteries with which literature review and writing was undertaken by graduate students at both master's and Doctoral levels. The paper used primary sources to gather data from graduate students' theses and proposals. Data from those sources revealed how literature review and writing showed different patterns depending on the nature of the research, and the specific objectives of the study. Similarly, different approaches were found to be suitable to different research contexts and methods. The challenges in writing and reviewing literature mainly springs from the failure to clearly define the research problem which propels clarity in the presentation of literature.

The ability to conduct an explicit and robust literature review by students, scholars or scientists is critical in producing excellent journal articles, academic theses, academic dissertations or working papers. A literature review is an evaluation of existing research works on a specific academic topic, theme or subject to identify gaps and propose future research agenda. Many postgraduate students in higher education institutions lack the necessary skills and understanding to conduct in-depth literature reviews. This may lead to the presentation of incorrect, false or biased inferences in their theses or dissertations. This study offers scientific knowledge on how literature reviews in different fields of study could be conducted to mitigate against biased inferences such as unscientific analogies and baseless recommendations. The literature review is presented as a process that involves several activities including searching, identifying, reading, summarising, compiling, analysing, interpreting and referencing. We hope this article serves as reference material to improve the academic rigour in the literature review chapters of postgraduate students' theses or dissertations. This article prompts established scholars to explore more innovative ways through which scientific literature reviews can be conducted to identify gaps (empirical, knowledge, theoretical, methodological, application and population gap) and propose a future research agenda.
