They can range from the selective (a very narrow area of research or only a single work) to the comprehensive (a larger amount or range of works).They can also exist as part of a larger work or stand on their own.
A literature review is an objective, concise, critical summary of published research literature relevant to a topic being researched in an article.
It does NOT reference and list all of the material you have cited in your paper.
In addition, all of its sections refer to the literature rather than detailing a current study.
In addition, this type of literature review is usually much longer than the literature review introducing a study.
The literature review published as its own article presents and analyzes as many of the important texts in an area of study as possible to provide background information and context for a current area of research or a study.
Stand-alone reviews are an excellent resource for researchers when they are first searching for the most relevant information on an area of study.
Here are some steps that will help you begin and follow through on your literature review.
Step 1: Choose a topic to write about—focus on and explore this topic.
When a literature review exists as part of an introduction to a study, it follows the structure of the Introduction itself and moves from the general to the specific—presenting the broadest background information about a topic first and then moving to specific studies that support your study, finally leading to your hypothesis statement.
The literature is often indistinguishable from the Introduction itself—the literature is INTRODUCING the background and defining the gaps your study aims to fill.
