1. Use a database or Google Scholar.
Here's an explanation of review articles from the UT Austin Library:
"Review articles are an attempt by one or more writers to sum up the current state of the research on a particular topic. Ideally, the writer searches for everything relevant to the topic, and then sorts it all out into a coherent view of the “state of the art” as it now stands. Review Articles will teach you about:
Unlike research articles, review articles are good places to get a basic idea about a topic.
In most databases and indexes, you can limit your search to include only review articles. Some databases might use the term "literature review," but it's the same thing. Set up your search like usual, then find the limit for review articles, select it, and run your search."
Emory Libraries does have a database devoted to review articles: Annual Reviews Online
1. Searching backward in time.
First, look for review articles which synthesize the findings of many previous studies. One way to locate a review article is by doing a keyword search in Web of Science and then refining your results by clicking Review under Document Types at the left-hand side of the page (see below example). Once you have found a review article, scan the references or works cited section to find older articles that are relevant to your research project. This method of searching informs you about how research on a specific topic has progressed up until that point in time.
Second, when you find a great research article, make sure to look at the references cited in that article.
2. Searching forward in time. Another useful way to locate relevant articles is to conduct a forward search. For example in Web of Science, locate an article that is important to your research project. Click on the number corresponding to Times Cited (see below example) to see newer articles that have cited this article. This method of searching informs you about how a particular article has influenced subsequent research on that topic.
