The Library provides a variety of different tools for finding scholarly resources (e,g, papers, theses, published articles, books, other media, manuscripts, other archival material). Some of these tools provide information about material that is physically (or virtually) present on campus (e.g. print books and journals, archival collections, theses), and some provide links to electronic materials to which we provide licensed access to the campus community (e.g. eBooks, electronic journal articles, databases).

The search box on the Library's home page provides keyword search of the following by choosing from the tabs:
