The Arnold Shaw papers (1927-2006) contain correspondence, newspaper articles, journal entries, promotional materials, and photographs. Shaw was a prolific writer and his papers also include articles, short stories, plays, and biographies written by him. In addition there are proofreader's notes, research material, and scratch copies for each of his fourteen books. The collection also contains papers from the various vocal groups and companies under contract with Shaw's music company, Mansion Music. Sheet music, some of which was written and produced by Shaw, assorted printed materials, and sound reels are also included.

The Sierra Club Toiyabe Chapter Records (1951 to 2021) are composed of files from Sierra Club officers and environmental activists in the Southern Nevada (formerly Las Vegas) Group of the Toiyabe Chapter. The collection documents the involvement of the Southern Nevada group in a variety of environmental concerns, such as air quality, transportation, urbanization, and nuclear issues, in which the chapter has expressed interest. The records are comprised of correspondence, memoranda, meeting minutes and agendas, newspapers, magazines, newsletters, pamphlets, press releases, legislation, recommendations, resolutions, and general information. Due to the group’s location in the heart of the Mojave Desert, the collection provides excellent case studies of significant changes in the post-World War II American environmental movement, notably the increased recognition of the worth of desert lands.
