CCOH has one of the largest archives of recorded histories in the world, and it is open to the public. We conduct or collect approximately 300-500 new hours of interview each year – which we then add to that archive. We hold over 8,000 interviews; over 1,000 of these are biographical interviews of major figures in philanthropy, government, human rights, media history, public health, science and medicine. We also conduct large-scale research and urban history projects as well as government and institutional histories. CCOH holds one of the largest oral history collections on the New Deal in the country, an expansive history of Social Security Administration, interviews with leaders of the American Civil Rights movements, women’s liberation and equality movements, anti-war movements, legal history, women in the visual arts, the Republican era in China, 1930s Argentina, and more.
