Ethel Cutler Freeman was an amateur Seminole specialist and research associate with the American Museum of Natural History. Her papers also reflect field work among the Arapaho, Shoshoni, Navaho, Pueblo, Hopi, Kickapoo, and people of the Virgin Islands, the Bahama Islands, and Haiti, and the music and chants of Africa, including those of the Maasai, Zulu, and Pygmies. A small amount of material relates to the Hoover Commission on Indian Affairs, of which Freeman was a member. Correspondents include several Seminole Indians and government officials, personal acquaintances, organizations, and associates of the American Museum of Natural History.

Harrington was a Bureau of American Ethnology ethnologist involved in the study of over one hundred American tribes. His speciality was linguistics. Most of the material concerns California, southwestern, northwestern tribes and includes ethnological, archeological, historical notes; writings, correspondence, photographs, sound recordings, biological specimens, and other types of documents. Also of concern are general linguistics, sign language, writing systems, writing machines, and sound recordings machines. There is also some material on New World Spanish, Old World languages. In addition, there are many manuscripts of writings that Harrington sketched, partially completed, or even completed but never published. The latter group includes not only writings about anthropological subjects but also histories, ranging from a biography of Geronimo to material on the history of the typewriter. The collection incorporates material of Richard Lynch Garner, Matilda Coxe Stevenson, and others. In his field work, Harrington seems sometimes to have worked within fairly firm formats, this especially being true when he was "rehearing" material, that is in using an informant to verify and correct the work of other researchers. Often, however, the interviews with informants (and this seems to have been the case even with some "rehearings") seem to have been rather free form, for there is a considerable intertwining of subjects. Nevertheless, certain themes frequently appear in his work, including annotated vocabularies concerning flora and fauna and their use, topography, history and biography, kinship, cosmology (including tribal astronomy), religion and philosophy, names and observations concerning neighboring tribes, sex and age division, material culture, legends, and songs. The fullness of such materials seems to have been limited only by the time Harrington had to spend with a goup and the knowledge of his informants.

The papers of Aleš Hrdlička, curator in the Division of Physical Anthropology, Department of Anthropology, United States National Museum of the Smithsonian Institution, offer considerable insight into the development of physical anthropology in the first half of this century. The papers include honors bestowed on Hrdlička, autobiographical notes, correspondence with many of the leading anthropologists of the day, anthropometric and osteometric measurements and observations (forming most of the collection), extensive photographs of Hrdlička's field work, manuscripts, research materials, and "My Journeys" (essentially a diary Hrdlička kept of his field work). In addition, there is material of a personal nature. The papers date from 1875 to 1966, but the bulk of the materials date from 1903 to 1943, the time of Hrdlička's career at the USNM.
