Scholarly articles are published in subject-specific journals. The articles in these journals are geared toward scholars and experts in their field. They undergo reviewing by other scholars in the field, known as the peer-review process.
To find out if a journal is scholarly/peer-reviewed, you can go to this database UlrichsWeb. Note that a peer-reviewed journal may include editorials or short news items that do not go through the full review process, but if the article is a full research piece, it can be considered "peer-reviewed."
One of the easiest ways to find scholarly peer-reviewed articles is to use OneSearch on the library home page (www.library.unr.edu). After OneSearch displays your search results, you can narrow them to "Scholarly & Peer-Review" publications using the filter on the left sidebar.
