These literature reviews are generally a bit broader in scope and can extend further back in time.
This means that sometimes a scientific literature review can be highly theoretical, in addition to focusing on specific methods and outcomes of previous studies.
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.
One way to conceive of a literature review is to think about writing it as you would build a bookshelf.
You don’t need to cut each piece by yourself from scratch.The literature review found at the beginning of a journal article is used to introduce research related to the specific study and is found in the Introduction section, usually near the end.It is shorter than a stand-alone review because it must limit its scope to very specific studies and theories that are directly relevant to this study.Its purpose is to set research precedence and provide support for the study’s theory, methods, results, and/or conclusions.Not all research articles contain an explicit review of the literature, but many do, whether it is a discrete section or indistinguishable from the rest of the Introduction.These guidelines are adapted primarily from Galvan (2006).Galvan outlines a very clear, step-by-step approach that is very useful to use as you write your review.It is not usually a linear process—authors often to go back and check the literature while reformulating their ideas.This also means you will not be writing the literature review at any one time, but constantly working on it before, during, and after your study is complete.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.
