The papers in the Abbott collection appear to have been brought together in the Smithsonian's Department of Anthropology in order to process ethnological specimens from Malaya and Indonesia and to prepare an exhibit and publications. Included are some of Abbott's original letters, notes, maps, and a considerable number of photographs. Most of these materials concern the Enggano, Jakun, and Dyak. Many other documents in the collection consist of copies of or extracts from Abbott's letters, the originals of which are now in the Smithsonian Institution Archives. There are also letters and other materials of Otis Tufton Mason and Walter Hough accumulated as they worked on the collection, many simple lists of accessions compiled in the Department of Anthropology, and a few manuscripts. In addition, there are printed materials that were apparently used by the department's staff for reference purposes. Some of the photographs made in Borneo in 1914 are by Henry Cushier Raven, a field assistant of Abbott and, later, a collector financed by Abbott. Additional materials of Abbott and Raven are in the Smithsonian Institution Archives, and their material (often duplicate photographs) are included in several collections in the National Anthropological Archives.
