The slave narrative is a type of literary genre involving the (written) autobiographical accounts of enslaved Africans, particularly in the Americas. Over six thousand such narratives are estimated to exist; about 150 narratives were published as separate books or pamphlets. In the United States during the Great Depression (1930s), more than 2,300 additional oral histories on life during slavery were collected by writers sponsored and published by the Works Progress Administration, a New Deal program. Most of the 26 audio-recorded interviews are held by the Library of Congress.
