Articles & Books tab on the Libraries' home page searches much of the library's content in a single search and is a great place to start.
Search settings can be changed on the results page.
To limit to just scholarly articles, check the box for Scholarly/peer-reviewed articles in the upper left of search results.
If the library doesn't have an article you want, request it via Interlibrary Loan. We'll get it for you, often in just a day or two. (Learn more about UR Interlibrary Loan in this YouTube video.)
In addition to Articles and Books, the Libraries also license specialized databases for particular disciplines. These databases for on broad areas of research and may accommodate specialized search terms.
