The Las Vegas Professional Men’s Club Records (1984-1997) consist of the constitution, meeting minutes, and organizational documents of the Las Vegas Professional Men’s Club, later known as the Las Vegas Men’s Club (LVMC). The LVMC provided a social outlet for gay men in Southern Nevada. The bulk of the materials date from the 1990s and include membership lists, event fliers, promotional materials, financial documents, and information documenting the club’s fundraising activities.

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.
