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.

The Mollie Gregory Collection of Oral Histories contains audio interviews and brief transcripts that focus on welfare, family, and women's issues in Nevada from 1970 to 1974. Gregory interviewed Nevada residents including Maya Miller, Ruby Duncan, and Mary Wesley, who described their lives during the anti-poverty and women's rights campaigns in the early 1970s. The collection documents views on welfare; the Equal Rights Amendment; race, discrimination, and civil rights; and political campaigns.
