What is a Literature Review?

Think of it as a review article since it offers a comprehensive summary of the state of the field's knowledge, research results, and methodological and theological contributions to the specific subjects.
Literature review does not simply mean summarizing the content, but appraising, analyzing, and synthesizing the research papers including articles, journals, scholarly articles, government reports, and more in a cohesive manner.
In other words, think of it as a map that shows paths that have been taken, identifying the gaps and research framework for the future. It is an important part of various academic writing such as dissertations, and theses.
How to Write a Literature Review
Define Your Purpose
It is important to define your purpose clearly to ensure that your literature review is focused and relevant. Without a clear understanding of why you’re conducting the review, your work may lack clarity and coherence.
There are a few questions to consider:
- What is the aim of your review?
- Either it be a standalone paper or a part of a dissertation?
- What type of review are you conducting?
- How does your topic align with your research?
Search for Relevant Literature
A thorough research ensures that your review is conducted comprehensively, includes credible resources, and aligns with your research objectives.
You can use the below-mentioned resources to locate credible literature:
- Google Scholar
- Web of Science
- PubMed
- Scopus
- JSTOR
While searching for the database, also consider what subject you're working on. For example, if you’re writing a literature review for work published in the social sciences field, you may choose PubMed to research your study. Similarly, for the multidisciplinary fields you can choose Web of Science and Scopus to make your research easier.
Evaluate the Sources
Not all the sources you find can be relevant to your literature review. Before deciding whether or not to incorporate it in your literature review, you need to evaluate the resources. By evaluation, you can ensure that they contain information that is valuable and pertinent.
You can evaluate the resources based on the given criteria.
- Relevance: Check the relevance of the sources you are utilizing for your literature review. Understand if they are answering your research questions.
- Credibility: Examine if your piece of work is peer-reviewed or published on a reputable platform.
- Recency: Make sure the resource you are using is up to date with the latest trends.
- Perspective: Understand and ensure that your literature review has a unique point of view or perspective.
Organize Your Literature
Organization is crucial for clarity. Therefore organize your resources for clear evaluation. You can group studies based on themes, methodologies, and chronologically to make sense of your findings.
Critically Evaluate The Sources
The game does not end by just summarizing the content. You need to critically evaluate the sources and examine their strengths, weaknesses, methodologies, and their relevance to your topic.
Identify the Patterns and Trends
To analyze the shift in ideas and patterns, pay close attention to the recurring ideas, concepts, and themes discussed by the different authors. Find out what are the dominant theories and how different scholars agree or disagree with them.
Structure Your Literature Review
Typically, the literature review can be structured similarly to the standard essay. It includes the following:
Introduction: Start your review with a broad introduction including the background information on the topic. In addition, you can also discuss the context, purpose, and scope of your review.
Body: The body of your literature review should contain the information that is relevant to your research queries. You need to structure the body logically and coherently. Adding subheadings in your review will help you present your ideas logically and also stay relevant to your research aim. Moreover, it is also important to analyze the key themes and ideas in your review rather than just summarizing them. Consider the important themes and discuss their gaps in understanding and disagreement between the different literature sources.
Conclusion: Wind up your review by demonstrating how you have answered the research questions. Plus, highlight and recapitulate the main themes, and propose future research.
Types of Literature Review
Which type of literature review you undertake depends on your personal preferences. However, the literature reviews differ based on the methodologies that are followed.
Narrative Literature Review
A narrative literature review provides a broad and descriptive overview of a specific topic without following any particular methodology. Unlike the systematic review, it is simpler and more flexible. It allows writers to explore and synthesize information to tell a coherent story. The narrative literature review is used to review a wide range of studies and provide the contextual framework for future research.
Systematic Review
The systematic review follows a structured approach to assembling, examining, and combining information. To search for the literature across multiple databases, you will need to follow specific and predefined criteria.
Meta-Analysis Review
Meta-analysis involves combining data from different literary sources driving to a single conclusion, often using statistical methods.
Theoretical Review
A theoretical review analyzes existing theories. It helps determine the relationship between theories and their relevance and provides a new theoretical framework.
Challenges in Writing a Literature Review
Let’s face it - writing a literature review is not a piece of cake. During the writing process, you can face a few challenges that can affect your productivity. We have mentioned below, have a look.
Information Overload
Having to deal with so much information might be daunting. Set selection criteria for the books you need to include in your review and keep your attention on what is pertinent.
Bias
Avoid cherry-picking studies that only support your argument. Aim for a balanced perspective.
