The University of Nevada, Las Vegas Special Collections Library houses unique, rare, and specialized research material that documents the history, culture and physical environment of the city of Las Vegas, the Southern Nevada region, the gaming industry, and the University of Nevada Las Vegas.
The collections include books, pamphlets, posters, serials and periodicals, scrapbooks, archives and manuscripts, maps, architectural drawings, photographs, video and audio tapes.
I visited the library recently to talk gambling with former director now Head of Exhibits Peter Michel, for it's here that you'll find "the world's greatest collection of material on gambling and related issues, including books, journals, company documents, and manuscript collections."
