The MGM Mirage Records on Mandalay Resort Group consists of materials from Mandalay Resort Group’s office of public relations and community affairs records, which was closed after Mandalay’s corporate merger with MGM Mirage in 2005. The files, dating from 1968 to 2005, provide documentation of Mandalay Resort Group’s external affairs and internal operations. They contain subject files, photographs, negatives, slides, correspondence, VHS tapes, corporate publications, press releases, press kits, wholesale room agreements, hotel ephemera, employee newsletters, and press clippings. Of particular interest are files and photographs documenting the planning, development, construction, and opening of the Mandalay Resort Group properties.

The John Klai II Papers (1983-2024) is comprised of the personal papers of American architect, John Klai II. Materials include commendations presented to Klai for his achievements in the architecture and interior design profession from organizations like AIA Las Vegas; the National Council of Architectural Registration Boards (NCARB); and the Nevada State Board of Architecture, Interior Design and Residential Design. The collection also includes digital images of plaques and trophies presented to Klai for his philanthrophic work in the Las Vegas community. The professional files in this collection include publications featuring the work of Klai Juba Wald architecture + interiors, Klai's 2015 AIA Fellowship submission portfolio, magazine features about Klai, and a commemorative photo book of Klai Hall at North Dakota State University. Also included are a small number of Klai's personal sports memorabilia, including tickets for the NCAA men's basketball tournaments from 1987 and 1989.
