A Literature Review is an account of what has been published on a topic by accredited scholars and researchers. When writing a literature review, your goal is to determine the current state of knowledge about a particular topic by asking, "What do we know or what do we not know about this topic?" In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are.
A literature review should:
include an overview of the subject, issue, or theory under consideration
group sources into categories and concepts (in support or against a particular position)
present connections between the sources
draw conclusions about those works that make the greatest contribution to the understanding and development of your subject
A full-length, stand alone literature review could be arranged like this:
Introduction
An introductory paragraph that provides an overview of the subject, issue, or theory under consideration
Additionally, you can also add a description of how you found sources and how you analyzed them for inclusion and discussion in the review (See below for tips on searching for information).
Body
The body should group sources into categories and concepts (in support or against a particular position) and present connections between the sources.
Summarize and synthesize your sources: Give an overview of the main points of each source and combine them into a coherent whole.
Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole.
Critically Evaluate: Mention the strengths and weaknesses of your sources.
Conclusion
Summarize the key findings you have taken from the literature and emphasize their significance
Address any gaps in the literature, what is missing, what work still needs to be done?
If you are doing a literature review as part of a research paper, typically your literature review will be shorter and will be just one section in your research paper. It should, however, contain the same elements above, and the introduction and conclusion sections will be shorter.
Tips on Searching for information found in the library at Minnesota State University, Mankato:
First, Identify main concepts or breaking down the topic into its component parts.
Take your research topic and pull out the main concepts.
List search terms = Identify terms or phrases you can use to search for information. For each main concept, identify synonyms and related terms, both narrower and broader
Use quotation marks around any words you want to search as a phrase. Example: "sustainable construction".
Combine search terms with AND and OR
AND will retrieve sources containing all the words. Use AND to combine your main concepts. Example: sustainable AND construction AND materials will bring back results that have with all three words.
OR will retrieve sources containing either term, broadening your search. Use OR to combine synonyms or related terms. Example: "sustainable building materials" OR "sustainable construction materials" will bring back results that have either the phrase sustainable building materials or the phrase sustainable construction materials.
NOT will retrieve sources that do not include the term. Example: building NOT skyscraper will bring back results that do not include the term skyscraper.
