The series contains a small amount of Himes's incoming and outgoing correspondence. The bulk of the correspondence documents Himes's professional relationships with G.P. Putnam's Sons editor William Targ and photographer and writer Carl Van Vechten. The letters between Targ and Himes date from when Targ served as editor and editor in chief at two different publishing companies, The World Publishing Company, where he was from 1942 until 1964, and G. P. Putnam's Sons, where he worked from 1964 until 1978. The series also includes one letter from Himes to Helen Meyer, editor at Dell Publishing Co. Inc and four letters from Himes to Roslyn Targ, wife of William Targ and owner of Roslyn Targ Literary Agency Inc.
