The Priscilla Reining papers, 1916-2007, primarily document the professional life of Reining, a social anthropologist and Africanist who worked for the American Association for the Advancement of Science (AAAS) from 1974 to 1989. Her area of specialty was sub-Saharan Africa, specializing in desertification, land tenure, land use, kinship, population, fertility, and HIV/AIDS. During the 1970s, she pioneered the use of satellite imagery in conjunction with ethnographic data. She is also known for her ground-breaking research in the late 1980s that showed that uncircumcised men were more susceptible to contracting HIV/AIDS than circumcised men. The collection contains correspondence, field research, research files, writings, day planners, teaching files, student files, photographs, maps, sound recordings, and electronic records. Reining's research files, particularly on the Red Lake Ojibwa, the Haya, HIV/AIDS, and satellite imagery, form a significant portion of the collection.
