Literature Review
What is a Literature Review?
A literature review is a comprehensive, strategic, and evaluative assessment of the published works, research and articles relevant to a particular subject area or research question. This way it can become an essential component of academic investigation, offering investigators, scholars and researchers an understanding of the general framework where the work they do fits within the academic realm. A literature review assembles information from numerous sources, and focuses on trends, controversies, and areas of uncertainty within the field to orient the development of future contributions to literature and to ensure that new claims have a basis in prior findings.
Types of Literature Review
There are several types of literature reviews, each serving a distinct purpose within the research process:
Narrative Review
It describes currently available literature without rigid adherence to the methodological approach. It generally presents themes, outcomes, and history of the topic under discussion.
Systematic Review
A systematic review is a highly stringent form of research that addresses specific research questions. It entails the use of well defined criteria for identifying the studies, whereby, data; are collected and analysed systematically using specific techniques.
Meta-Analysis
This is a quantitative technique that integrates measures of effect from several studies in order to arrive a single measure. Meta-analysis is a stronger measure of effect than individual research, and can make it easier for scholars to compare results and find associations across different findings.
Scoping Review
Scoping reviews enable the researcher to place the literature under study on a topic into different categories by defining key concepts, documenting the body of existing data on the researched subject, and highlighting the existing research gaps. They are especially helpful if applied to relatively new topics for which few articles have been published.
Theoretical Review
Theoretical reviews pertain to historical developments concerning theories associated with a subject. They learn how in their practice theories are used further or modified employing the results of prior research.
What is a Literature Research Proposal?

Some Things to Bear in Mind Before Writing a Literature Review
When writing a literature review, consider the following guidelines:
Relevance
Make sure that each source employed in the process of the review refers to the research question or the area of concern.
Objectivity
Try not to prejudice when judging sources. Able to accept ideas that are different from his/her own and present them objectively.
Comprehensiveness
Make an endeavor to approach a variety of sources that include the recent ones or the pioneering pieces of work. Deeper analysis raises the sample credibility, which leads to increasing the result credibility.
Structure
All the comments made in the review are to be interlinked coherently. Subdivide groups where it is beneficial to align them in terms of themes, methodologies, or chronological order to make the content ~cohesive’.
Critical Analysis
Go beyond mere summarization. Evaluate the potential and weakness of each source as well as their interaction.
Citation
It is important always to ensure that all the literature quoted particularly in research papers is cited appropriately to avoid plagiarism. The review writer should use consistent citation style throughout the writing of the review.
