As a student pursuing a nursing course, you will likely encounter assignments that require writing a literature review. A solid understanding of the literature review definition and its purpose will greatly enhance your ability to effectively complete these tasks.
Literature Review Definition
A literature review is an academic survey of scholarly articles, books, and other sources relevant to a specific research topic or area of study. It’s not just a summary of source materials; instead, it involves a critical analysis of these works in relation to the research you’re conducting.
According to the USC Upstate Library, a literature review serves the purpose of reviewing the existing research and literature on a specific topic, providing an overview and analysis of the available information. This process allows you to familiarize yourself with the current state of knowledge on your topic and to understand the major theories, concepts, and key figures associated with your area of study.
The process of writing a literature review involves searching for relevant literature, evaluating and analyzing these sources, organizing your findings into a logical order, and presenting a cohesive narrative that provides a comprehensive overview of the existing literature on your topic. For more guidance on this process, refer to our guide on how to write a literature review.
Purpose of Literature Reviews
The literature review has several key purposes in academic research. Primarily, it allows you to establish a theoretical framework for your study and provides context for your research question. By carrying out a literature review, you can assess the current state of research on a topic, enabling you to understand what is already known about the topic and how extensively it has been researched.
In addition, a literature review helps in identifying experts on a particular topic by revealing which researchers have written the most on the subject, making them key resources for consultation in current research projects.
Lastly, conducting a literature review lets you identify key questions about a topic that require further research. This process helps in discovering new angles and gaps in current research that need exploration. By identifying these gaps, you can determine the unique contribution that your research can make to your field of study.

Components of Literature Reviews
As you delve deeper into the literature review definition, it’s essential to understand the components that make up a literature review.
Key Elements in a Literature Review
A literature review aims to provide an overview of existing academic literature on a specific topic. It evaluates the strengths and weaknesses of the author’s arguments, summarizes available research, and draws conclusions about the topic. It helps in determining existing research, identifying gaps, opportunities for further research, and areas needing more resources (Rasmussen Library).
The literature review should be intelligently structured and organized to allow the reader to grasp the study’s key arguments. Instead of describing various groups of literature reviewed, it is recommended that the literature be broken into conceptual categories or themes.
Within a review of a given source for a literature review, various aspects can be covered, including the purpose, scope, methods, results, discussion points, limitations, and implications for future research.
When organizing a literature review, it can be done by synthesizing topically, where sources are discussed together based on shared topics, or by summarizing individually, where each source is discussed separately in its paragraph or section (UIS).
Importance of Literature Reviews
The literature review holds a critical role in your academic journey. It identifies the state-of-the-art knowledge in a particular field, clarifies information that is already known, elucidates implications of the problem being analyzed, links theory and practice, highlights gaps in the current literature, and places the dissertation/thesis within the research agenda of that field.
The literature review not only translates your abilities in information literacy, the language domain, and critical writing but also transforms you as a student and hints at the contents of other chapters for the reader.
A sound and sophisticated literature review can indicate a robust dissertation/thesis (Source) and is beneficial for students, as it helps in understanding current conversations on a chosen topic, which in turn prepares them to write their own unique argument (UIS).

Conducting a Literature Review
Navigating the academic landscape requires a firm understanding of the purpose and process of conducting literature reviews. In this section, we will walk through the steps of conducting a literature review and discuss the benefits derived from this essential academic exercise.
Steps in Conducting a Literature Review
A literature review allows you to review existing research and literature on a specific topic, providing a comprehensive overview and analysis of the available information. Here are the primary steps you should follow when conducting a literature review:
- Define the research question: Begin with a clear, focused research question. This will guide your literature search and analysis.
- Conduct a literature search: Utilize databases and academic resources to find relevant research articles. Be sure to record all references.
- Review and analyze the literature: Read each article carefully and identify the key findings, theories, and arguments. Assess the strengths and weaknesses of each study.
- Write the review: Organize your findings and write your review. Be sure to summarize the main findings, discuss the current state of research, and identify gaps in the literature.

Benefits of Conducting a Literature Review
Conducting a literature review offers several benefits, particularly for students engaged in nursing research (UNF Library Guides):
- Assessing the Current State of Research: Literature reviews allow you to understand what is already known about a particular topic and how extensively it has been researched.
- Identifying Experts: By revealing which researchers have written the most on a particular topic, literature reviews help identify key resources for consultation in your research projects.
- Identifying Research Gaps: Literature reviews allow you to find new angles and gaps in current research that require further exploration.
- Determining Effective Methodologies: By examining methodologies used in past studies, you can gain valuable insights into effective approaches for your own research.
- Building a Knowledge Foundation: Completing a literature review provides a firm foundation of knowledge on your chosen topic, guiding the direction of your research and providing clarity on which experts to consult for additional questions.
The importance of literature reviews in academic scholarship cannot be overstated. They play a critical role in scholarship as they support evidence-based practice and help keep up with the growing literature. Furthermore, review articles constitute a valuable work of research in their own right and are often cited and downloaded more often than any other type of published article.
In your academic journey as a nursing student, a solid understanding of the literature review definition and the process of conducting a literature review is essential. It will not only enhance your research skills but also contribute significantly to your growth and development as a scholar.
Types of Literature Reviews
In your academic journey, you will encounter different types of literature reviews, each with its own unique purpose and structure. Understanding these variations is crucial in your quest to comprehend the literature review definition fully.
Overview of Different Literature Review Types
Two common types of literature reviews you may encounter are the systematic review and the realist review.
Systematic reviews aim to aggregate, appraise, and synthesize all empirical evidence that meets specific eligibility criteria to answer a narrow research question and support evidence-based practice. This type of review is comprehensive and leaves little room for bias, making it a valuable resource for informing policy and practice.
On the other hand, realist reviews aim to make sense of heterogeneous evidence about complex interventions in diverse contexts by unpacking the mechanism of how interventions work and assessing how variations in outcomes can be explained. This type of review provides a deeper understanding of how and why interventions produce different outcomes in different contexts.
Characteristics of Review Articles
Literature reviews can take two major forms: the “literature review” or “background” section within a journal paper or a chapter in a graduate thesis, and the “review article” which constitutes an original and valuable work of research in and of itself.
Review articles, in particular, are often highly valued as they provide a comprehensive overview of a particular topic and are frequently cited and downloaded more often than any other type of published article. These articles play a critical role in scholarship as they help keep up with the growing body of literature in various fields, including eHealth.
| Type of Literature Review | Purpose |
|---|---|
| Systematic Review | To aggregate, appraise, and synthesize all empirical evidence that meets specific eligibility criteria to answer a narrow research question. |
| Realist Review | To make sense of heterogeneous evidence about complex interventions in diverse contexts by unpacking the mechanism of how interventions work. |
| Review Article | To provide a comprehensive overview of a particular topic. |
