Consists of forty-one photographs of Indigenous students and adults, white teachers, and United States government officials operating mobile libraries at ten different Native American day and boarding schools in Arizona during the New Deal era. According to handwritten annotations on the backs of photographs, these schools are identified as the Casa Blanca Day School in what is now the Gila River Indian Community (Bapschule, Arizona); Quajote Day School (possibly Quijotoa); Phoenix Indian School; Fresnal Canyon; Fort McDowell Day School in what is now the Fort McDowell Yavapai Nation; and five schools in or near what is now the Tohono O'odham Nation (referred to in the captions as the Papago Indian Reservation and Sells, Arizona), including the Kerwo, Vamori, Choulic, Chuichu, and Santa Rosa Ranch day schools. According to a list maintained by the National Native American Boarding School Healing Coalition, Phoenix Indian School and Santa Rosa Ranch were also boarding schools. Based on the locations of these schools, the children photographed likely include those from Tohono O'odham, Akimel O'odham (Pima), Pee-Posh (Maricopa), and Yavapai communities, and possibly others. While children at boarding schools were forcibly taken from their homes, Indigenous children attending both day and boarding schools during this time period were subject to brutal assimilationist policies by the United States government and school staff.

These images document visits to the schools by mobile libraries operated by the United States Department of the Interior's Department of Indian Service Library and Motion Picture Service. Although the photographer is unknown, the images may have been taken and captioned by government officials who drove the two buses marked as "U.S. Department of the Interior – Indian Service Library and Motion Picture Service" and "U.S.I.S. Traveling Library." One of the officials posing with the former bus is identified as Pierre and can be seen in one image setting up chairs and a screen for an outdoor film screening. Most of the photographs show students posed with teachers and school staff in front of schools or with the mobile libraries, while others depict the grounds and buildings of various schools, as well as scenes of the Arizona desert. The teachers, all but one of whom are white women, are identified by name in the captions as Katherine S. Shorten, June Steele, Maxine Brubacker, Mary Blochbinger, Grace Taylor, Edna Harris, Miss Pike, and R. E. Meyer. Some photographs also include Indigenous adults who are described in the captions as bus drivers and housekeepers. Salina Enos is the only Indigenous person described by her name in a caption, and she is photographed both with a class and with her cousins at the Quajote Day School.
