You may search for scholarly articles using either the default search on the library homepage, Article Search, or a Database. When using the default search or the Article Search after you get search results you may limit to scholarly (peer reviewed) on the left side of the page. Most databases also have an option to limit to scholarly or peer reviewed sources
JSTOR is a great database and all full text covering humanities and social sciences. NOTE: JSTOR does not include the most recent articles, only those that are about 5 years old and back.
