Archives and Special Collections welcomes students, faculty, visiting scholars and members of the general public to explore the Library’s rare books and pamphlets, manuscript collections, photographs, the University Archives, and the Map Collection. The Department’s major purposes are to acquire these materials, make them available for use, and preserve their integrity for future generations.
