This collection consists of correspondence, written articles and manuscripts, newspaper clippings and scrapbooks, pamphlets and programs, periodicals, research documents related to Native American tribes, documents detailing land conservation efforts, personal materials, photos, and other material. The correspondence consists of both personal and professional letters and telegrams, some pertaining to manuscripts. Other personal correspondence consists of postcards, greeting cards, and invitations. Some correspondence exists outside the correspondence series in order to preserve the context of the material. A majority of the manuscripts in the collection were written by Harry C. James but other authors are also represented. The collection includes newspaper clippings relating to Native Americans, environmental conservation, nature, Harry C. James, and other topics. The scrapbooks contain newspaper clippings about “Odds and Ends,” a story by Harry C. James, and Southern California regions. The majority of the Native American material is related to the Hopi and Cahuilla tribes but other tribes are also represented. The environmental conservation documents contained in the collection discuss Southern California regions, particularly the Coachella Valley and the San Jacinto and San Gorgonio wilderness areas. The collection contains a variety of photographs and negatives that depict different people and landscapes. Many of the photographs included are of identified families with whom James kept in contact with, as well as unidentified individuals. There are also many Native American photographs, including several photos of the Hopi tribe.
