The libraries at Penn State include a main collection (Pattee Library) and seven branch libraries. The humanities and social science collection, the Arts Library, and the Life Sciences Library are housed in Pattee (pronounced Pa-tee). The branch libraries include the Architecture Library, Earth and Mineral Sciences, Education Library, Mathematics Library, Pollock Library and the Physical Sciences Library. Pollock library, or the undergraduate library, has the largest student computer lab on campus and has the advantage of being near Tyson. University Libraries

Pattee library has a colossal collection of books, periodicals, newspapers and microforms in the arts and humanities as well as the biological, natural and social sciences. Maps, documents, manuscripts and rare books can also be found. Most books and other library materials circulate with the exception of periodicals, reference books, and items in special collections. Users who wish to borrow materials must have a current University ID.

A technological asset of the University libraries that has revolutionized library service is the fully automated Library Information Access System (LIAS), This online system has replaced the traditional Penn State card catalog and also provides access to Big 10 library databases, the Library of Congress, and numerous subject specific search engines. LIAS also enables patrons to browse the libraries’ holdings in call number order without going to the shelves.

Any graduate student who has determined that the Library does not own a particular work needed for research may request that the item be obtained through Interlibrary Loan (ILL). Requests may be submitted to the Interlibrary Loan Office located on the fifth floor of the Paterno wing at which point ILL decides whether it will provide a certain item. Interlibrary Loan is a supplementary service provided to assist researchers in gaining access to materials not otherwise available at University Park.
