Writing a Literature Review -5 Key Steps, Challenges and Best Practices for Writing Chapter 2 of a Thesis or Dissertation

Introduction

Writing a Literature Review is easier than most students assume. Think about Writing a Literature Review as assembling the available information you already have, evaluating, synthesising and communicating the author’s message in your own words while driving home the similarity and differences with your topic and the gap you intend to fill.

At the outset of a research project, conducting a literature review is crucial to understanding the existing knowledge base on a given topic or question.

A literature review involves analyzing and evaluating various sources, such as academic articles, books, reports, and other relevant materials, to understand the current state of research on a topic comprehensively. By synthesizing this information, researchers can identify gaps, inconsistencies, and areas for further inquiry.

The importance of conducting a literature review cannot be overstated. It provides researchers with a broad understanding of existing research, helping to identify potential research questions and methodologies and avoid duplicating existing work.

It also situates the researcher’s work within the larger context of their field, highlighting the unique contributions their research can make. Mastering the art of writing a literature review is essential for any research project, as it ensures that researchers are aware of the current state of knowledge on their topic, allowing them to build on existing research and produce high-quality outcomes.

5 Key Steps in Writing Literature Review

Step 1: Identifying Your Research Question and Scope

Before beginning a literature review, a clear research question and scope is essential. Identifying the right research question can help guide the entire process and ensure the literature review is focused and relevant to the research project.

A research question should be specific, measurable, achievable, relevant, and time-bound (SMART) and reflect the research’s main aim. On the other hand, a clear scope helps narrow down the research question and define the boundaries of the literature review. It can also help identify the sources to be included and excluded from the review.

A well-defined scope is crucial when dealing with complex or broad topics, as it helps ensure the review is manageable and targeted. Therefore, when starting a literature review, it’s important to take the time to carefully consider and define the research question and scope to ensure the success of the entire project.

Step 2: Searching for Relevant Literature: Strategies and Tools

Searching for relevant literature is a crucial step in writing a literature review. It involves using various strategies and tools to find the most relevant and credible sources for the research question. One of the most important strategies is combining search terms, Boolean operators, and search limits to refine the search results.

Boolean operators, such as “AND,” “OR,” and “NOT,” can help to narrow or broaden the search based on the specific needs of the research question. Other important strategies include searching databases specialising in the research topic and reviewing the reference lists of relevant articles to identify additional sources.

Several tools are available to help researchers manage and organize their search results while Writing a Literature Review, such as reference management software, citation indexes, and search alerts. Researchers can use various strategies and tools to find the most relevant and up-to-date literature for their literature review.

Step 3: Evaluating the Quality and Relevance of Sources

Once a researcher has compiled a list of potential sources for the literature review, the next step is to evaluate the quality and relevance of those sources. This involves critically analysing the sources to determine their credibility, reliability, and suitability for the research question.

Several criteria can be used to assess the quality and relevance of sources, such as the author’s credentials, the publication’s reputation, the research methodology used, and the currency of the information. Evaluating the quality and relevance of sources is particularly important in today’s era of “fake news” and misinformation, where researchers need to be vigilant about the sources they use.

By carefully evaluating the quality and relevance of sources, researchers can ensure that their literature review is based on credible and reliable information, enhancing their research’s overall quality and validity.

Step 4: Organizing Your Literature: Creating an Annotated Bibliography or Matrix

Once a researcher has evaluated the quality and relevance of their sources, the next step is to organize them effectively. One common way of organizing sources is to create an annotated bibliography, a list of references accompanied by a summary and evaluation of each source’s content and relevance to the research question.

An annotated bibliography provides a quick reference for the researcher and can also help to identify common themes or gaps in the literature. Another way to organize sources is to use a matrix. This table allows the researcher to categorize and compare sources based on key features, such as research design, methodology, or theoretical framework.

A matrix can help identify patterns and relationships among sources and visually represent the literature review. By organizing their literature in a structured and logical manner, researchers can facilitate the writing process and ensure that their literature review is well-organized, coherent, and comprehensive.

Step 5: Synthesizing Your Literature: Writing a Narrative or Conceptual Synthesis

After organizing the literature, the final step in writing a literature review is synthesising the information. Synthesizing involves combining information from various sources to create a coherent and meaningful narrative or conceptual framework.

There are two main approaches to synthesizing the literature: narrative synthesis and conceptual synthesis. A narrative synthesis involves summarizing and describing the key findings and themes from the literature. In contrast, a conceptual synthesis involves identifying and analyzing the theoretical or conceptual frameworks that underlie the literature.

A conceptual synthesis is more appropriate when the research question is based on a theoretical framework or when the aim is to develop a new theory. Regardless of the approach used, synthesizing the literature involves critically analyzing the information and presenting it in a way that is accessible and relevant to the research question.

By synthesizing the literature effectively, researchers can contribute to the field and provide a strong foundation for their research.

Common Challenges in Writing a Literature Review and How to Overcome Them

Writing a literature review can be challenging, even for experienced researchers. One common challenge is determining which sources to include and exclude, as a vast amount of literature may be available on a topic. As discussed earlier, it’s important to define a clear research question and scope to overcome this challenge.

Another challenge is maintaining objectivity and avoiding bias in selecting and interpreting sources. To overcome this challenge, it’s important to critically evaluate the quality and relevance of sources and avoid cherry-picking sources that only support one’s views.

Additionally, organizing and synthesizing the literature can be daunting, especially when dealing with complex or interdisciplinary topics. To overcome this challenge, it’s helpful to use tools such as annotated bibliographies or matrices and to seek feedback from colleagues or advisors. By recognizing and addressing these challenges, researchers can produce high-quality literature reviews contributing to their field of study.
