What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

How to Write a Literature Review Introduction?

Literature review introductions are vital because they provide a roadmap for the reader. Crafting a compelling literature review introduction is crucial in presenting your research question, the relevance of the study, and the context in which your research fits within the existing literature. This initial section captures the essence of your research and guides your reader through the journey of understanding the research problem and the solutions your study offers. They explain the importance of the study, highlight gaps in existing research, and establish the significance of the research question. By clearly outlining the focus of the literature review and the themes to be explored, the introduction helps readers understand the direction and research scope . This context is essential for comprehending the study's relevance in the broader field. A well-crafted introduction can engage the reader’s interest and encourage further topic exploration.

Writing a literature review introduction involves several key steps. Each step ensures that your introduction is coherent, engaging, and informative.

1. Start with a broad context

Begin your literature review introduction by presenting a broad overview of the specific topic. This sets the stage for your research and places it within a wider context. For example, if you are reviewing literature on climate change, start by discussing its global impact and relevance. Explain how climate change affects the environment, economy, and society. This broad context helps frame the specific research question within a larger perspective, making it more understandable and relevant to the reader.

2. Narrow it down

Once the broad context is established, narrow down to the specific aspects of the topic that your literature review will address. This helps focus the review and guide the reader through the key themes and ideas you will talk about. For instance, within the topic of climate change, you might focus on its impact on coastal ecosystems or agricultural productivity. By narrowing it down, you clarify the scope of your review and ensure that your analysis is precise and targeted.

3. Highlight the importance of the study

Write why your literature review is important. Discuss the gaps in existing literature and how your review will address these gaps. Emphasize the significance of your study in contributing to the field. Highlighting the importance of your study justifies your research and shows how your work advances understanding in the field. For example, if other studies on climate change have primarily focused on physical impacts, your review might explore socio-economic effects, thereby filling a crucial gap.

4. State the research question

Clearly state your research question. It provides a clear direction for your review and helps in organizing the literature reviewed. It also makes it easier for researchers to follow your argument. A well-defined question or thesis statement is the backbone for your literature review and guides the selection and evaluation of journal articles. It ensures that your review remains focused and relevant throughout.

5. Outline the structure of the review

Provide a brief overview of the structure of your literature review. Mention the main sections and key themes you will cover. This helps set expectations for the reader and provides a clear roadmap for the review. Outlining the structure at the outset helps to organize your thoughts and present them logically. It allows the reader to anticipate the flow of the review and understand how different sections are interconnected.

6. Discuss the methodology

If you are writing a literature review as a full paper, briefly discuss the methodology you used to select and evaluate the literature review. Explain how you identified relevant literature, the criteria for inclusion and exclusion, and the approach you took in reviewing the literature. This helps readers understand the rigour of your research process . Discussing the methodology introduces your approach to reviewing the literature and enhances trustworthiness.

7. Provide a summary of key findings

Summarize the key findings from the literature reviewed. Highlight the main theories, models, and concepts relevant to your research question. This contextualizes your research and demonstrates your understanding of the existing literature to other researchers. A summary of key findings provides a snapshot of what has been done in the field.
