The collection consists primarily of audio interviews made by John Gerassi with Jean-Paul Sartre between 1970 and 1974. A companion group of interviews with Sartre's family, friends, and foes was made in 1973. Included in this group are: Raymond Aron, Simone de Beauvoir, Arlette Elkaim-Sartre, Claude Lanzmann, and J. B. Pontalis. The majority of these interviews have transcripts. Among the other papers are various works by Sartre on Ethics, in the form of lecture notes and manuscript drafts prepared in the 1960s as well as a list by Sartre of books he read in different periods of his life. Also included are notes by John Gerassi on the origin of the collection.
