The Stardust Hotel and Desert Inn Hotel Photographic Negatives collection consists of black-and-white photographic negatives depicting the Stardust and Desert Inn hotels from approximately 1962 to 1967. The images depict annual and one-time events held at both hotels, including sporting events such as golf and tennis, fashion shows and beauty contests, weddings, and conventions for local and national associations. A significant amount of the collection documents the long running Lido de Paris show at the Stardust. Also included in the collection are interior views of Stardust and Desert Inn casino floors, pool side lounges, and guest rooms, as well as exterior and aerial views of the hotel properties located in Las Vegas, Nevada.

The Human Radiation Experiments Records (1949-1995) contain reports from the National Environmental Policy Act (NEPA), the Advisory Committee on Human Radiation Experiments (ACHRE), and the U. S. Department of Energy (DOE). Also included are newspaper clippings, a court case brought by the National Association of Radiation Survivors (NARS), and cancer research papers. With the goal of building an atomic bomb using plutonium extracted from uranium, the material also examines the outcomes of radiation exposure done on humans during the late 1940s and early 1950s at the Oak Ridge Nuclear Facility in Tennessee.

Papers are comprised of photographs, newspaper clippings, and correspondence dating from the 1950s to the 1980s collected by Steven Hart, son of the Las Vegas, Nevada chef, Nat Hart. The papers include information about Steven Hart's childhood and his service in Vietnam. Also included in the collection are photos of Steven Hart's father, Nat Hart.
