The library is home to the University of Wyoming's rare books collection, consisting of over 50,000 items and is sponsored by the Clara Toppan endowment. The majority of the materials are printed books, although there are newspapers, magazines, broadsides, illuminated manuscripts, and other materials. Collecting subjects include the American West, British and American Literature, Exploration and Travel, Religion, Hunting and Fishing, historic children's books, and examples of the book arts.
