The National Anthropological Archives and Human Studies Film Archives in the department of Anthropology, Collections and Archives Program collect and preserve historical and contemporary anthropological materials that document the world's cultures and the history of anthropology. Their collections represent the four fields of anthropology – ethnology, linguistics, archaeology, and physical anthropology – and include fieldnotes, journals, manuscripts, correspondence, photographs, maps, sound recordings, film and video created by Smithsonian anthropologists and other preeminent scholars.
