Papers include typescripts of deLappe's memoir; oral history and interview transcripts; subject files on Byron Randall, Anton Refrigier, Emmy Lou Packard and Anita Whitney; deLappe's files released under the Freedom of Information Act from the Federal Bureau of Investigation; and sketches of the 1966 United Farm Workers march from Delano to Sacramento.

In addition to correspondence with Jessica Mitford, the collection contains news clips, manuscripts and articles that deLappe wrote about Mitford, found in the Pele deLappe Writings – General file. The several files on deLappe's memoir, along with the transcripts contained in the Oral Histories and Interviews folder, provide insight into deLappe's experience as a San Francisco artist and activist. The subject file on Anita Whitney contains six unidentified slides from an exhibit or scrapbook relating to Anita Whitney. The file on Anton Refregier contains documents relating to the Rincon Annex murals, painted by Refregier in 1946-1947; deLappe assisted him with some of the panels. A photographic negative of part of the mural has been relocated to the Labor Archives' Photographic Negative Collection.
