Mastering the Role of Literature Reviews in Research

A literature review is a comprehensive overview of studies related to a specific field of research. It serves the purpose of identifying and summarizing all the pertinent research that has been conducted on a particular subject. The primary aim of a literature review is to provide a focused examination of existing literature, concentrating on a limited number of pivotal studies that are closely related to your research topic, as opposed to amassing a broad array of studies that may not have direct relevance.

Literature reviews serve several essential purposes:

1. Evaluate Past Research:

By compiling and analyzing relevant resources, a literature review allows you to assess the existing body of research in your chosen field. This evaluation is crucial for gaining a comprehensive understanding of the current state of knowledge and for avoiding redundancy in your own work. It helps you build on previous findings rather than duplicating them.

2. Identify Experts:

While conducting a literature review, you can identify authoritative researchers and scholars who have substantial expertise in your specific area of interest. Recognizing these experts is beneficial because you can reach out to them for guidance, collaboration, or to seek assistance when you encounter challenges in your research. Their insights can prove invaluable to your own study.

3. Identify Key Questions:

One of the ultimate goals of a literature review is to contribute something new to the ongoing conversation in your field. Through the process of reviewing existing research, you can pinpoint critical questions that have yet to be answered or explored. This identification of gaps in knowledge helps you define the specific objectives of your research and adds depth to your work.

4. Determine Methodologies Used in Past Studies:

By examining how other researchers have approached similar topics, you gain insights into various methodologies and approaches that have been successful or unsuccessful. This knowledge enables you to make informed decisions about the methodology you’ll employ in your research. If you find a previously used methodology that aligns with your objectives, you can save time by adapting and building upon it rather than starting from scratch.

In essence, a literature review serves as a foundational step in the research process, helping researchers navigate the existing landscape of knowledge, identify gaps or opportunities, and make informed decisions about how to contribute meaningfully to their field of study. It’s a crucial aspect of academic and scientific research that enables researchers to build on the work of their predecessors while striving to advance the understanding of their chosen subject matter.

Incorporating Literature Reviews in the Introduction and Discussion Sections

In scholarly writing, the inclusion of literature reviews in both the introduction and discussion sections of your manuscripts offers several advantages. However, the approach to presenting these reviews differs between these sections.

What to Include in the Literature Review of the Introduction Section:

The literature review featured in the introduction should serve several crucial purposes:

1. Introduction of the Topic:

Begin by introducing the research topic, providing readers with an initial understanding of what the study addresses.

2. Establishment of Significance:

Clearly establish the significance and relevance of your research within the broader context of the subject area.

3. Overview of Relevant Literature:

Offer a concise but comprehensive overview of the pertinent literature related to your research topic. This provides readers with an understanding of the existing knowledge base.

4. Contextualization of the Study:

Use the literature to create a context for your study, demonstrating how it fits into the larger academic or practical landscape.

5. Identification of Knowledge Gaps:

Highlight gaps in current knowledge or areas where previous research falls short, underscoring the need for your study.

6. Illustration of Knowledge Advancement:

Explain how your research will contribute to the expansion or enhancement of knowledge within the field.

While the literature review plays a substantial role in the introduction section, it’s essential to avoid certain practices, including:

Excessive Elaboration:

Avoid going into extensive detail about the studies mentioned in the literature review; instead, maintain a concise overview.

Overreliance on Support:

Resist the temptation to use studies from the literature review as strong support for your own research objectives in the introduction.

Direct Quoting:

Generally, refrain from directly quoting studies from the literature review in the introduction.

The key to effectively integrating the literature review into the introduction lies in striking the right balance. While it is acceptable to reference other studies, remember that they should not overshadow the primary focus of establishing a solid foundation for your manuscript. The literature review should primarily function as a tool to frame and justify your research, demonstrating its significance and relevance within the existing body of knowledge.

Incorporating Literature Reviews in the Discussion Section

In the discussion section of your manuscript, focus on your findings, using the literature review to support your study. You can use literature reviews in three key ways:

1. Contextualization:

Establish a foundation for presenting your findings and ideas by referencing relevant studies.

2. Comparison:

Compare your results to existing literature to highlight similarities and differences.

3. Contribution:

Explain how your study advances the field.

Avoid common mistakes such as including irrelevant studies, citing secondary sources, or relying solely on abstracts when referencing prior work.


Mastering the art of literature review is an indispensable skill for researchers. By understanding its role in the introduction and discussion sections, researchers can build a solid foundation, identify knowledge gaps, and contribute meaningfully to their fields. In the introduction, it sets the stage, while in the discussion, it contextualizes findings and showcases contributions. Avoiding pitfalls like excessive elaboration or reliance on unrelated studies is key to harnessing its power effectively. In essence, a well-crafted literature review is the cornerstone of impactful research.
