What is meant by the Review of Literature?

The review of literature, also known as a literature review, is a critical analysis and synthesis of the existing research on a particular topic. It involves identifying, evaluating, and synthesizing published works, scholarly articles, and other relevant sources of information related to the research question.

The purpose of a literature review is to provide an overview of the existing research on a topic, identify gaps in the literature, and provide a foundation for the research that follows. It helps researchers to understand the current state of knowledge on a particular topic, identify key themes and concepts, and identify areas where further research is needed.

A literature review typically involves a comprehensive search of databases, academic journals, and other sources of information related to the research topic. The sources are then evaluated for their relevance, credibility, and quality, and the key findings and themes are summarized and synthesized in the literature review.

What is the Difference Between the Background of a Study and Literature Review?

The terms “background” and “literature review” are often used interchangeably, but they have different meanings and serve different purposes in a research paper.

The background section of a research paper provides contextual information about the research topic, including its history, significance, and relevance. The background section sets the stage for the research question and provides the reader with the necessary context to understand the research question and the research that follows. The background section typically includes a brief overview of the research topic, its historical development, and any relevant contextual information that the reader needs to understand the research question.

On the other hand, the literature review is a critical analysis and synthesis of the existing literature on the research topic. The literature review summarizes, synthesizes, and evaluates the key ideas and findings of previous research studies relevant to the research question. The literature review aims to identify gaps in the literature, highlight areas of agreement and disagreement among researchers, and provide a foundation for the research that follows.

In essence, the background section provides contextual information about the research topic, while the literature review critically evaluates the existing literature on the topic. The background section is typically shorter and more general than the literature review, while the literature review is more detailed and specific. Both sections are important for providing context and understanding of the research topic, but they serve different purposes in a research paper.

Conducting a Literature Review

Conducting a literature review involves a systematic and comprehensive search for relevant literature on a particular topic. It is essential to search for literature from different sources, including academic journals, books, conference proceedings, and grey literature. The following steps can help conduct a literature review:

Step 1: Define the research question

The first step in conducting a literature review is to define the research question. It sets the foundation of the entire review process, providing focus and direction for the analysis. The research question guides the search strategy, shapes the structure of the review, helps to evaluate the relevance of the sources of information, and determines the analysis and synthesis of the literature. It ensures that the review is focused on a specific area of interest and avoids being too broad or unfocused.

Step 2: Identify relevant literature

Identifying relevant literature is the second step in conducting a literature review. A comprehensive search should be conducted using various search engines and databases. The search should be based on the keywords related to the research question. It is important to ensure that the search is comprehensive and includes all relevant literature.

Step 3: Evaluating the quality of the sources

Once the sources of information have been identified, the next step is to evaluate the quality of the sources. This involves assessing the reliability, validity, and relevance of the sources. This can be done based on the following criteria:

• The author’s qualifications and expertise.
• The methodology used in the research.
• The relevance of the research to the research question.
• The credibility of the source.

Step 4: Identify key themes

Once you have analyzed the sources, the next step is to identify key themes that will guide the structure of your literature review. These themes should be based on the research question and objectives and should reflect the main findings of the literature review.

Step 5: Group studies by theme

After identifying key themes, the next step is to group studies by theme. This will help to ensure that the review is structured logically and that all relevant studies are included.

Step 6: Synthesize and analyze the literature

Once the studies have been grouped by theme, the next step is to synthesize and analyze the literature within each theme. This involves critically evaluating the findings of each study, identifying research gaps, and drawing conclusions about the state of research on the topic.

Step 7: Organize the literature

After evaluating the quality and relevance of studies, the next step is to organize the literature into meaningful categories or themes. This can be done by identifying commonalities or patterns in the research and grouping studies accordingly. The literature can be organized chronologically, thematically, or based on the methodology used in the research. We have discussed how to organize a literature review in the following section in detail.

How to Organize a Literature Review?

There are three common approaches to organizing a literature review: chronological, thematic, and methodological. Here’s a detailed explanation of each approach:

• Chronological approach

The chronological approach involves organizing the literature review by the order in which studies were conducted or published. This approach is useful when examining the historical development of a research topic or when tracing the evolution of research ideas over time. It can be particularly useful when the research question involves understanding the historical development of a topic, or when the research question is focused on a particular period.

• Thematic approach

The thematic approach involves organizing the literature review around key themes or concepts that emerge from the studies. It can help to identify patterns and trends in the literature and to highlight areas of consensus or disagreement among researchers. This approach is useful when the research question is broad and complex, and when there is a need to synthesize multiple studies with differing methodologies and findings.

• Methodological approach

The methodological approach involves organizing the literature review by the research methods used in each study. This approach is useful when the research question involves evaluating the strengths and weaknesses of different research methods or when the research question is focused on a particular research method. This approach can help to identify gaps in the research, highlight areas of controversy, and provide insights into the limitations and opportunities of different research methods.

It is important to note that these approaches are not mutually exclusive, and researchers may choose to combine them to best address their research question. For example, a researcher may choose to organize their literature review chronologically and thematically, to provide a comprehensive overview of the historical development of a topic and to highlight key themes and concepts that have emerged over time. Ultimately, the choice of approach will depend on the research question, the available literature, and the goals of the literature review.

Writing and Structuring the Literature Review

Writing a literature review involves synthesizing the collected literature and presenting it in a coherent and meaningful manner. Here’s how to write a literature review appropriately:

Step 1: Introduction

The introduction of a literature review serves as the opening section of the paper and provides an overview of the topic being reviewed. The introduction typically contains the following elements:

1. Background information: The introduction provides the background and context of the research topic, including its history, significance, and relevance. This information helps the reader to understand the importance of the research question and the existing literature on the topic.
2. Scope of the literature review: You must clearly define the scope of the literature review, including the research question or objective of the review, the specific research areas or themes to be covered, and the criteria used to select the sources of information.
3. Research gap: The introduction should identify the research gap or problem that the literature review seeks to address. This may include a discussion of the limitations or gaps in the existing research, as well as the potential implications of the research question.
4. The methodology used in conducting the literature: You must briefly discuss the search strategy used to identify the sources of information, including the databases, search terms, and inclusion/exclusion criteria, and also the process used to select the sources of information, including the criteria used to evaluate the relevance and quality of the sources (often found in published and standalone literature reviews rather than in the literature review section of a research paper article).
5. Objectives or purpose: The objectives or purpose of the literature review, including the specific research questions or hypotheses that the review seeks to answer must be presented in this section.
6. Overview of the paper: The introduction should provide an overview of the organization and structure of the paper. This helps the reader to understand the flow of the paper and the key sections that will be covered (written in case of a standalone piece).

1. Summary of the literature: The body of the literature review summarizes the existing research on the topic. It should provide a comprehensive overview of the literature, including key themes, concepts, and findings. The summary should be organized logically and coherently which allows the reader to follow the flow of the literature review.
2. Evaluation of the literature: The body of the literature review evaluates the quality and credibility of the existing research. This involves analyzing the methodology, results, and conclusions of the studies and assessing their strengths and weaknesses.
3. Identification of gaps in the literature: The body of the literature review identifies the gaps in the existing research and areas where further research is needed. This involves highlighting areas where the literature is inconsistent, contradictory, or inconclusive.
4. Synthesis of the literature: The body of the literature review synthesizes the existing research to provide a new understanding of the topic. This involves identifying common themes and patterns across the literature and integrating them into a coherent and comprehensive understanding of the topic.
5. Discussion of implications: The body of the literature review discusses the implications of the research for theory, practice, and future research. This involves synthesizing the findings of the literature review and drawing conclusions about the significance of the research for the field.

Step 3: Conclusion

The conclusion of a literature review is the final section of the paper where the main findings and implications of the review are summarized. The conclusion covers the following elements:

1. Summary of the key findings: The conclusion provides a concise summary of the main findings of the literature review. It should highlight the key themes, concepts, and conclusions that emerged from the analysis and synthesis of the existing research.
2. Implications for research: The conclusion discusses the implications of the literature review for future research. This involves identifying areas where further research is needed, highlighting gaps in the literature, and suggesting new directions for future studies.
3. Implications for practice: The conclusion discusses the implications of the literature review for practice. This involves identifying areas where the research has practical implications for professionals, policymakers, and other stakeholders.
4. Limitations of the review: The conclusion acknowledges the limitations of the literature review. This involves discussing the strengths and weaknesses of the methodology, the scope of the review, and the quality and relevance of the sources of information.
5. Final thoughts: The conclusion provides some final thoughts on the topic of the literature review. This could include a discussion of the significance of the research, its potential impact on the field, and its relevance to broader social and cultural issues.
