Tertiary sources are excellent starting points! Subject encyclopedias, handbooks and overviews are scholarly, tertiary works written by experts on a variety of topics. These resources give you succinct overviews of your topic, explain scholarly arguments, point out interesting questions, and refer you to especially key sources.
In Collins Library, the print reference collection is located on the first floor, and most of the online reference collection is available in one of the database collections listed below. Use Primo to identify subject encyclopedias in either format; or ask a librarian for recommendations.
