From 1936 to 1938, ex-slaves in the United States were interviewed and related stories of what it was like to be a slave in America and what life was like after freedom finally came. Told by the former slaves themselves, the narratives were collected under the auspices of the Work Projects Administration (WPA). Nearly 4,000 narratives were recorded. They are gathered in ABC Clio e-Book collection under the title America Slave and separated by individual and groups of states.
