The James Cashman Sr. Photograph Collection (approximately 1905 to 1975) consists of black-and-white photographic prints, negatives, slides, and albums as well as a glass plate negative. The photographs depict four major subjects: Cashman's family, friends, and associates; Cashman's businesses; the Hoover Dam and Colorado River; and various locations across Nevada.

The University of Nevada, Las Vegas Photograph Collection (approximately 1900-2004) depicts the development of the university and the city of Las Vegas. The collection includes images of campus buildings, student activities, sports teams, past university presidents, and Las Vegas in the early twentieth century. Early images depicting the surrounding area are included in this collection as well.

The Penelope Ruchman Collection of Las Vegas, Nevada Casino Professionals Oral Histories includes interviews conducted by Ruchman from approximately 1999 to 2001 of casino industry workers who worked in Las Vegas, Nevada. The majority of interviews were conducted by Ruchman in their office at Gambler's Book Shop (GBS), but some where conducted in interviewee's homes and offices, or over the phone. The collection represents Ruchman's efforts to interview and document a generation of early casino industry workers that were quickly aging. The project was intended to be compiled as a definitive history of Las Vegas and American gambling, entitled "After the Gold Rush." The project was permanently postponed in the fall of 2001 when Ruchman left GBS to work for Park Place Entertainment as a corporate business and operations analyst, and later as casino operations director for Caesars Palace. Not all interviews have digital transcripts available.
