One should not confuse review articles with peer-reviewed journals. The former relate to the attempt of a particular writer or writers to summarize the current progress of research on a certain topic. Typically, a writer searches information that corresponds to the topic, sorts it out, and then organizes it into a logically structured and coherently written article.
So, review articles will provide you with information about the following:
The team of people working in a certain area of research;
The newest discoveries and advancements in the field of research;
Limitations and weaknesses of the research;
Current debates and discussions on the topic;
Future prospects of the research findings and ideas.
Unlike the common research articles, review articles will provide you with the underlying idea about a specific research topic.
How to Find Review Articles?
Mostly, when you are using indexes and databases for searching articles, you can limit your search to finding only review articles. Some databases may contain a name “literature review,” but it is actually the same thing as a “review article.” So, set up your search as usual, then indicate the limit for the literature reviews, and then you can run your search.
If you open up MedGen, you can look for review articles on genetic disorders. For example, you might type in “achondroplasia” and click on the “search” button. Also, pay attention to the list of filters to the left side of the webpage. In the category of “Article Type,” you will see the link entitled “Review.”
An advanced tip for you: after you have run your search process, look through all results on the webpage, scroll the page down and pay attention to the “search details” section to the right of the webpage. These search details are a sign that your search actually worked out well and the MedGen added the term to your search history.
