Online catalogs allow you to search for material that a library holds in it's collection. The University Library of Columbus uses IUCAT (Indiana University's online catalog system). In order to discover what physical items we have in our library, simply perform your search and limit the results to the "Columbus" library. That option will be available to you as a "limiter" on the left hand side of the search page. If you're in the library, there are professional librarians and staff available to help you find what you're looking for.
