The Joyce Mack Papers are mainly comprised of photographs and ephemera documenting Joyce Mack and her family from the 1970s to 2014. Photographs in the collection depict political and community events, the Mack family, and their interaction with politicians. An invitation, newspaper clipping, and transcript of a speech by Joyce Mack document various honors that were betstowed upon Joyce Mack and her husband, Jerome D. "Jerry" Mack.

The Thalia Dondero Political Papers (1934-2003), contain correspondence, pamphlets and reports used by Dondero to conduct official business, as well as information on county and city budgets, social and health services, liquor and gaming, planning, public works, environmental impact reports and a large section on water management. Dondero served as a Clark County Commissioner for twenty years and engaged in numerous other civic and political activities. The bulk of the materials are derived from Dondero's last four years in office, 1990-1994, but a few items from Dondero's earlier career are included.
