Library OneSearch and most of the databases within the library such as EBSCOhost and ProQuest contain a mixture of popular and scholarly/peer reviewed content.
These databases will include an option to limit your search results to only scholarly/peer reviewed articles. In most cases, simply checking this box will only pull up articles of this type. Look for the links marked Scholarly/ Peer Reviewed, Scholarly (Peer Reviewed) Journals, Peer Reviewed, or something similar.

There are occasionally non-scholarly articles published in scholarly journals, like editor's notes and book reviews. A good rule of thumb is to look to see if an article includes citations and a list of references. If not you may not want to use it.
Databases with only scholarly sources
JSTOR, SAGE, and Project Muse contain only scholarly material, so there is no need to designate it by checking a box.
If you still have questions you can chat in real-time with a librarian here.
