In 1974 Leland D. Case, a noted historian, journalist, Black Hills native and co-founder of the Westerners International, donated his private library, of approximately 5,000 volumes, to Black Hills State University. This donation is the core of one of the most thorough western history collections in the area. Today the Case Library contains over 15,000 volumes covering all aspects of western history. The collection is especially strong in South Dakota, Black Hills and Native American history.

Books are not the only items in the Case Library. The library also contains many manuscript collections . This guide gives a brief description of the manuscript collections. More detailed information is available in the individual collections’ finding aids, which are available at the Case Library.

The Leland D. Case Library for Western Historical Studies continues to be interested in gifts of books, manuscripts, photographs and other primary source materials, particularly those which relate to the history of western South Dakota and the Black Hills.
