I am looking for peer-reviewed articles
Answer
If an article has been peer-reviewed, that means other experts in the field read drafts of the article to be sure it met high academic and research standards. Peer-reviewed articles tend to be written on a very narrow topic or specific research question, use highly specialized terminology, and be rather long with many citations.
Scholarly articles can be peer-reviewed, but aren't always. They are written by experts and are considered reliable sources, and may be just as long and as narrowly focused as peer-reviewed articles.
Most library databases have features built in to help find scholarly and peer-reviewed articles. Look in the right or left margins of your search results for ways to narrow your search. Usually, it's a matter of checking a box.
