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.
