When and Why Do We Write a Literature Review?

A literature review is written for several reasons and it depends on the purpose of the review and the stage of the research project. Here are some common reasons why and when we write a literature review:

As a standalone document: In some cases, a literature review may be written as a standalone document, such as a review article, to provide an overview of existing literature on a particular topic. This is often done by experts in a particular field or subject area to provide a comprehensive analysis of the state of knowledge in the field.
As part of a research proposal: A literature review is typically included as part of a research proposal to provide a rationale for the proposed research. The literature review helps to demonstrate that the proposed research is relevant, important, and builds on existing knowledge.
At the beginning of a research project: A literature review is often conducted at the beginning of a research project to inform the research design, methodology, and data collection. By reviewing existing literature, researchers can identify gaps in knowledge, evaluate the quality of previous research, and identify appropriate methods and tools for collecting and analyzing data.
During the research project: A literature review may also be conducted during the research project to inform ongoing data collection and analysis. As new information becomes available, researchers may need to revise their research questions or methods, and a literature review can help to guide these revisions.
At the end of a research project: Finally, a literature review may be conducted at the end of a research project to summarize the key findings and identify areas for future research. This can help to inform the dissemination of research findings and contribute to the advancement of knowledge in a particular field or subject area.

Professional experts can offer valuable insights and guidance in various aspects of writing a perfect research paper, including developing a strong research question, conducting a thorough literature review, and presenting a clear and convincing argument.

What Makes a Literature Review Standout?

A literature review is an essential part of any research project, and a well-written review can make a significant impact. Here are some key elements that can make a literature review standout:

Clear research question: A standout literature review should have a clear research question that guides the review and keeps the focus on the topic.
Thorough search strategy: A comprehensive search strategy that includes multiple databases, relevant keywords, and a range of sources, such as books, articles, and reports, ensures that the review is comprehensive and includes the most up-to-date research.
Critical analysis: A standout literature review should include a critical analysis of the literature, evaluating the quality of previous research, identifying gaps in knowledge, and highlighting contradictions and controversies.
Synthesis of information: The literature review should synthesize information from multiple sources, identifying key themes, concepts, and ideas related to the research question.
Logical organization: A standout literature review should be logically organized, with a clear structure that guides the reader through the review. This may include organizing the review chronologically, thematically, or by methodology.
Clear writing style: A standout literature review should be written in a clear and concise style, using appropriate language and terminology, and avoiding unnecessary jargon or complex terminology.
Appropriate referencing: The literature review should include appropriate referencing, following a consistent referencing style and providing accurate and complete citations for all sources.
Contribution to knowledge: A standout literature review should make a contribution to knowledge, either by identifying gaps in the literature that need further research, or by synthesizing information in a way that provides new insights or perspectives on the topic.

While we are discussing literature review, it is important to learn how to write a hypothesis. Developing a clear and testable hypothesis is a crucial component of the literature review process, as it helps to guide the direction of the review and informs the research question that will be investigated.

Components of a Literature Review

Typically, literature reviews adhere to a standard framework of introduction, body, and conclusion. However, if the review forms part of a larger research paper, the introduction and conclusion sections may be brief, with the main emphasis placed on the body section. On the other hand, if the literature review stands alone, the introduction and conclusion sections will be more detailed, providing an opportunity to expound on the research objectives, methods, and findings independently from the discussion of the literature itself.

Introduction

The introduction part of a literature review provides an overview of the research question or topic, and explains the purpose and scope of the review. It should also provide a clear and concise thesis statement that summarizes the main argument or focus of the review.

The following are some key elements that an introduction part of a literature review should contain:

Background information: The introduction should provide some background information on the research question or topic, including why it is important and relevant to the field of study. This information helps the reader understand the context of the review.
Purpose and scope of the review: The introduction should clearly state the purpose and scope of the literature review. This helps the reader understand what the review will cover and what its main focus will be.
Significance of the review: The introduction should also explain why the review is significant and what contribution it makes to the existing body of knowledge on the topic. This helps the reader understand the importance of the review and why it is worth reading.
Thesis statement: The introduction should end with a clear and concise thesis statement that summarizes the main argument or focus of the review. The thesis statement should be specific and should guide the reader through the review.

Body

The body part of a literature review contains the main content of the review, which summarizes and synthesizes the literature relevant to the research question or topic. The body section of a literature review typically includes the following components:

Search Strategy: This section explains the methods used to identify and select the literature. It should include the databases and search engines used, the keywords and search terms used, and any inclusion or exclusion criteria used to select the relevant literature.
Literature Synthesis: This section summarizes the key findings from the literature, identifies common themes or patterns, and highlights gaps in knowledge. The literature synthesis should be organized thematically or chronologically, depending on the purpose of the review.
Critical Analysis: This section evaluates the quality of the literature. It should include an evaluation of the methodology, data collection methods, and data analysis techniques used in each study. It should also identify any biases or limitations in the literature and discuss their implications for the review.
Discussion: This section discusses the implications of the literature review for the research question or topic. It identifies areas for future research, makes recommendations for practice, and synthesizes the key findings of the literature review into a cohesive narrative.

The body part of a literature review should be well-organized and clearly written, with a logical structure that guides the reader through the review.

Conclusion

The conclusion of a literature review summarizes the main findings and key insights from the review and provides a final perspective on the research question or topic. The following are the key elements that a conclusion part of a literature review should contain:

Summary of key findings: The conclusion should provide a brief summary of the main findings from the literature review. This summary should include the key themes, trends, and patterns identified in the literature, as well as any significant gaps or limitations in the research.
Implications for research and practice: The conclusion should discuss the implications of the literature review for future research and practice. It should identify areas for further research, including unanswered questions or gaps in the literature. It should also discuss the practical implications of the findings for practitioners, policymakers, or other relevant stakeholders.
Strengths and limitations: The conclusion should briefly discuss the strengths and limitations of the literature review, including any methodological or conceptual limitations that may have affected the findings.
Final perspective: The conclusion should provide a final perspective on the research question or topic, and should highlight the significance of the review for the field of study. It should also provide a final synthesis of the key findings, and should reiterate the thesis statement in light of the evidence presented in the review.
