The Byrd Wall Sawyer Collection primarily consists of Byrd's research files on Nevada from 1930 to 1970. The materials concentrate on her monograph, "Nevada Nomads," as well as her co-authored textbook, "Here is Nevada." The collection also includes speeches, journal articles, memos, research note cards and papers, correspondence, informational booklets and pamphlets, maps, photographs, audiovisual materials, and newspaper articles and clippings.

Collection is comprised of correspondence, speeches, essays, meeting minutes, photographs, research materials, publications, press clippings, awards, and event programs (1941-2011) that document the life of Henry Schuster, and his work with his wife Anita. Materials are mainly related to the Holocaust and to Holocaust memory and survivor organizations (especially the Holocaust Survivor's Group of Southern Nevada, which the couple founded, and L’Œuvre de Secours aux Enfants). Genealogical information is also included, as well as records of Henry Schuster’s time in the U.S. Army and his studies at the Manhattan Technical Institute.

The Chester R. Longwell Professional Papers (1886-1974) document Longwell's professional career as a geologist and his pioneering field work in Clark County, Nevada. Included are Longwell's field notes; manuscripts, articles and speeches related to geology; personal and business correspondence; professional publications; subject and name files; specimen tags; photographic prints, negatives, and slides; and geological and topographical maps, primarily of Nevada, California, Arizona, and Utah.
