A literature review is a survey of the scholarly literature published on a given issue, research topic, or theory. Rather than providing a new research insight, a literature review lays the groundwork for an in-depth research project analyzing previous research. Type of documents surveyed will vary depending on the field, but can include:
A literature review is also the component of your assignment, article, or other academic work which synthesizes what you found in your research; it provides a description, summary, and critical evaluation of each work. Your literature review should include:
Determine the Scope of the Paper or Project:
Do you know what you are looking for? Can you describe your project using one simple sentence or can you phrase the project as a question? Without a clear idea of the project, you may not be able to determine which are the best resources to search, what terminology should be used in those resources, and if the results are appropriate and sufficient.
If you're having difficulty getting your project described succinctly, try using a PICO chart to identify the concepts involved:
Create the Search Strategy
Take the simple sentence or question that describes what you are looking for. What are the concepts in the sentence? Are there synonyms that describe the same concept?
Determine what Resources to Use:
What resources you'll use for your literature review depends on what types of materials you want to find.
Search, Read, Refine and Repeat:
Now it's time to apply your search strategy in the resources you've decided to use.
6. Redo your search strategy according to what you found in step #5 and rerun the search in the resources again.
7. You may need to repeat this cycle several times before you are able to identify the best terminology to use in each resource.
Published findings are called the Literature"
Your search for them is a "Review"
