Notable projects of the FWP included the Slave Narrative Collection, a set of interviews that culminated in over 2,300 first-person accounts of slavery and 500 black-and-white photographs of former slaves. Many of these narratives are available online from the above-named collection at the Library of Congress website. Folklorist Benjamin A. Botkin was instrumental in insuring the survival of these manuscripts. Among the researchers and authors who have used this collection are Colson Whitehead for his Pulitzer Prize-winning novel, "The Underground Railroad".
