Literature Review

A literature review is a type of academic writing that summarizes and evaluates the existing knowledge on a specific topic. It is often part of a larger research project, such as a thesis or a dissertation, but it can also be a standalone assignment. The purpose of a literature review is to demonstrate your understanding of the relevant literature, identify gaps or controversies in the field, and justify your own research question or hypothesis.

What is a Literature Review?

A literature review is not simply a summary of sources. It is an analytical and critical evaluation of the literature that relates to your research topic. You need to compare and contrast different perspectives, arguments, methods, and findings, and show how they are connected or different from each other. You also need to identify the strengths and weaknesses of the literature, and point out any gaps or limitations that need further investigation.

A literature review should have a clear structure and organization. It should include an introduction, a body, and a conclusion.

Introduction

The introduction of your literature review should:

- Provide some background information on your topic and its significance.

- Define the scope and focus of your literature review. What are the main themes or issues that you will address? What are the key terms and concepts that you will use?

- State your research question or hypothesis, and explain how it relates to the existing literature.

- Provide an overview of the structure and organization of your literature review. How will you group and order the sources that you will discuss?

Body

The body of your literature review should:

Discuss the sources that are relevant to your research topic in a logical and coherent way. 

You can use different criteria to group and order your sources, such as chronological, thematic, methodological, or theoretical.

Analyze and evaluate each source in relation to your research question or hypothesis. 

How does it contribute to your understanding of the topic? What are its main arguments, methods, findings, and implications? How does it compare or contrast with other sources?

Synthesize and integrate the sources that you have discussed. 

How do they relate to each other? What are the similarities and differences among them? What are the gaps or controversies in the literature? How do they support or challenge your research question or hypothesis?

Conclusion

The conclusion of your literature review should:

- Summarize the main points and findings of your literature review.

- Evaluate the current state of knowledge on your topic. What are the main strengths and weaknesses of the literature? What are the implications for future research?

- Restate your research question or hypothesis, and explain how your literature review has addressed it.

- Provide some recommendations or suggestions for further research on your topic.
