The Nancy Wier Papers on Rock Art in Southern Nevada (approximately 1930-2003) contain photographs, notes, research, and publications focused on rock art (rock writing) found in the Southern Nevada Region. Wier founded the Southern Nevada Rock Art Enthusiasts (SNRAE) in 1992, and the photograph albums document trips across Nevada, Southern California, Utah, and Arizona. The photograph albums are grouped by site location, and the description was taken directly from Wier's albums. The majority of the collection documents rock writings in Southern Nevada.

The Lois Sagel Papers on Nevada Wilderness Preservation (1989-1995) consist of the papers of Lois Sagel, an environmentalist and advocate for the preservation of Nevada’s wilderness. The collection primarily documents the campaigns surrounding the efforts to expand Red Rock Canyon National Conservation Area (1994) as well as to designate the Spring Mountains National Recreation Area (1993). Additionally, it contains information on minor land exchanges and the Question 5/S.B. 189 bond issue to fund state parks (considered in 1989 and 1990). Most of the collection is comprised of newspaper clippings, correspondence, memoranda, photographs, and photo slides.
