Project files include research materials consulted by Bunche, reports generated by him and/or his affiliates, and photocopies of business correspondence. Audiotapes include transcriptions of taped interviews with Bunche, mostly from the 1960s. Clippings and memorabilia include articles by and about Bunche, along with reviews and letters to him.
