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.
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.
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.
Determine 2-3 important concepts (depending on the length of your article) that are discussed in the literature; take notes about all of the important aspects of this study relevant to your topic being reviewed.
For example, in a given study, perhaps some of the main concepts are X, Y, and Z.
The following are some of the most important elements that a literature provides.
Literature reviews can differ in structure, length, and amount and breadth of content included.
Use thought maps and charts to identify intersections in the research and to outline important categories; select the material that will be most useful to you review.
Step 4: Describe and summarize each article—provide the essential information of the article that pertains to your study.
