LITERATURE REVIEW: Step by step guide for writing an effective literature review

A literature review is a comprehensive summary and evaluation of the literature relevant to a specific research question or topic. Here is a step-by-step guide for writing an effective literature review:

1. Define your research question or topic: Before you begin searching for literature, it’s important to have a clear understanding of what you’re looking for. This will help you focus your search and identify key words and phrases to use in your literature search.
2. Search for relevant literature: Use a variety of sources, such as academic databases, books, and journal articles, to identify relevant literature. Keep track of the sources you find, and make sure to note any important information about each one, such as the author, publication date, and main findings.
3. Read and evaluate the literature: As you read, take notes and evaluate the relevance, credibility, and reliability of each source. Look for patterns, themes, and gaps in the literature, and think about how each source contributes to your understanding of the topic.
4. Organize your literature: Once you have a good understanding of the literature, organize it into categories based on themes, research methods, or other relevant factors.
5. Write the literature review: Begin the literature review by providing an overview of the research question or topic, and then organize the literature into themes or categories. Summarize the main findings of each source, and evaluate the strengths and limitations of the literature. Finally, draw conclusions about the state of the literature and identify any gaps or areas for future research.
6. Proofread and revise: Before submitting your literature review, make sure to proofread it carefully and revise it as needed. Check for typos, grammar errors, and consistency in formatting.

Note: above steps can be followed as per your supervisor guidance, as some of the steps are optional and might have different weightage in different fields.

Features of a Good Literature Review

A good literature review has several key features that distinguish it from other types of written work. Some of the key features of a good literature review include:

1. Clarity and coherence: A good literature review is well-organized and easy to follow. It should have a clear introduction that sets the stage for the rest of the review, and the body of the review should be divided into logical sections that build on one another.
2. Comprehensive coverage: A good literature review covers a wide range of relevant literature, including both primary sources (such as research articles and books) and secondary sources (such as review articles and meta-analyses).
3. Critical analysis: A good literature review critically evaluates the literature, rather than simply summarizing it. This includes identifying strengths and limitations of the research, highlighting key findings, and pointing out gaps or inconsistencies in the literature.
4. Synthesis: A good literature review should be able to present a synthesis of the literature, which means making connections between different studies and authors, highlighting similarities and differences, and providing a sense of the overall state of the literature on the topic.
5. Objectivity: A good literature review is objective, meaning that it should be impartial and unbiased. It should not include any personal opinions or hypotheses.
6. Current and Up-to-date: A good literature review should include current, up-to-date references that are relevant to the research question or topic.
7. Proper citation: A good literature review should be properly cited, following a consistent citation style and formatting, so that other researchers can easily find and reference the sources that were used.
8. Relevancy: A good literature review should be directly related to the research question or topic and should only include literature that is directly relevant and important for understanding the research question.

It is important to note that the importance of these features may vary depending on the research field, type of literature review and guidelines set by the supervisor or publisher.

Parts of a Literature Review

A literature review typically has several parts that are designed to provide a comprehensive and critical overview of the existing research on a specific topic. These parts include:

1. Introduction: The introduction provides background information on the research question or topic, explains the purpose and scope of the literature review, and states the main research questions or objectives.
2. Search methods: This section describes the methods used to search for and select relevant literature, including the databases, keywords, and inclusion/exclusion criteria that were used.
3. Summary of findings: This section provides a summary of the main findings of the literature, organized according to themes or subtopics. It should include key findings, important trends or patterns in the literature, and any inconsistencies or gaps in the research.
4. Analysis and synthesis: This section provides an in-depth analysis of the literature, highlighting the strengths and weaknesses of individual studies, and synthesizing the findings of multiple studies. The analysis should address how the literature contributes to the overall understanding of the research question or topic.
5. Conclusion: The conclusion provides a summary of the main findings of the literature review, emphasizes the key contributions of the literature to the research question or topic, and points out areas for future research.
6. References: A list of all the references cited in the literature review, using a consistent citation style.

It is worth noting that, depending on the field and supervisor’s instruction, the above parts may not be required or may have different titles and emphasis. The overall structure of a literature review may also vary depending on the type of literature review, such as systematic review, scoping review etc.
