Types of literature reviews

The following are the different types of literature reviews found in writing:

  • Systematic reviews

A systematic review involves a detailed and comprehensive overview of existing evidence of a formulated research question. It consists in identifying, appraising, and synthesizing all relevant studies on a specific topic. The objective of a literature review is to document, analyze, and provide a summary of a clearly defined research topic in a scientific pattern. It focuses on a specific issue usually found in a cause and effect form.

  • Argumentative review

Argumentative review analyzes literature to support or reject an argument or a deeply embedded assumption established in the existing literature. The main focus is to provide a contrary point of view. However, an argumentative review poses a significant problem of biasness.

  • Integrative reviews

An integrative review critiques and synthesizes secondary literature about the research topic to generate new frameworks and perspectives on the subject. A good integrative review meets the same requirements as the primary data in terms of clarity, consistency, and replication.

  • Theoretical review

A theoretical literature review is used in establishing existing theories, the relationship between them, and the extent to which they have been researched. It helps in developing a new hypothesis to be tested. The primary purpose is to show that existing theories are inadequate for solving new research problems.

  • Historical reviews

Historical reviews are used to examine research throughout a certain period, the first occurrence of an issue and track its development. The primary purpose of the historical reviews is to align research in a historical context and show its relationship with current events and possibly predict the direction for future research.

  • Narrative literature reviews

A narrative literature review is a comprehensive and critical summary of the literature. It helps in establishing a theoretical framework and context for your research. A narrative literature review provides conclusions about a particular topic and address inconsistencies in the existing research.

Writing a credible literature review

The following guidelines will help you to compose an excellent literature review:

  • Search for relevant literature

The key to writing a useful review is identifying and looking for relevant literature and databases. The importance of conducting a literature search is to gather the information and relevant evidence required in your literature review.

  • Evaluate and select sources

Selecting relevant sources to use in your literature review requires careful evaluation and selection. It’s essential to evaluate the sources that are most relevant to your question. Your sources should have credible and reliable facts and statistics. Using credible sources to support your arguments is more likely to translate into high quality and authentic reviews.

The best sources for a literature review are scholarly articles since they have been written by experts and are more accurate and reliable. While evaluating your sources, it’s crucial to identify the principal authors and publications that will influence your research question.

  • Identify arguments and gaps.

Before beginning a review, its crucial to understand the relationship and connections between the sources you have read. To develop an excellent literature review, you need to identify emerging trends and patterns, conflicts and contradictions, recurring concepts, and gaps or weaknesses that need to be addressed.

  • Structure your review

A literature review should have an introduction, body, and a conclusion. In your introduction, you should define your research topic and provide an appropriate context for your literature review, explain the organization of the literature review, and state the scope of the review.

The body should organize the literature according to their context, provide a relationship of your topic and the subject of discussion, and narrow down your literature review to the specific focus of your research.
