The Jane M. Rosenthal papers contain a wide variety of historical and contemporary audio recordings, texts, elicitations and grammatical descriptions of Nahuatl, particularly the variety spoken in Tlaxcala, Mexico, both from the research of Rosenthal and others. Fieldwork in Tlaxcala (including photographs), archival research in Mexico and Chicago, and the work of many scholars that formed the Friends of Uto-Aztecan are represented.

The Virginia D. Hymes Papers focus primarily on the Sahaptin language research of Virginia Hymes and several others between the 1970s and 1980s. They contain several extensive lexical card files of Sahaptin, original field notes, Sahaptin texts and a dictionary, notes toward an unpublished dissertation, works by others (especially Eugene Hunn, David and Kathrine French, and Bruce Rigsby on Sahaptin, and Noel Rude on Nez Perce/Niimi'ipuutímt), and smaller amounts of teaching files, conferences, correspondence, and personal and administrative files.

The William O. Bright papers consist particularly of extensive correspondence relating mostly to his later academic work, a number of field notebooks from North America and India, publications on and by Indigenous North Americans (especially Karuk and other Californian tribes) and from linguistic societies, his own research and publications, and extensive lexical slip files (especially on Karuk, Spanish borrowings, and copies of Daythal Kendall's Takelma and Kalapuyan files). Many audio recordings are also present, some of which are duplicates of those at the California Language Archive. In addition to the materials browsable through the finding aid, Bright's email correspondence and computer files can be accessed onsite at the APS. William Bright's career extended to a wide variety of linguistic work, including Native Californian languages and literatures, Native American place names, editorships of major linguistics journals, and writing systems of the world.

Anthropologist and ethnographer Frank Gouldsmith Speck was one of Franz Boas' early graduate students and from 1907 till his death in 1950 spent his career in a variety of positions at the University of Pennsylvania, including its Museum of Archaeology and Anthropology. Unlike most of his contemporaries, Speck chose to study the cultures of Indigenous peoples of eastern North America, especially the Haudenosaunee, Cherokee, and peoples speaking Algonquian languages, such as Anishinaabe, Wabanaki, Innu, Lenape, and other Algonquian peoples within the eastern United States. Speck spent a larger amounnt of time in the field than was typical of most ethnographers, collecting documentary information and physical objects. The Frank G. Speck Papers consist of 15.5 linear feet of Speck's professional correspondence, field notes, lecture notes, and manuscripts of published and unpublished works. The material focuses on the Eastern Woodlands Indians, particularly the Catawba, Cherokee, Creek, Delaware, Houma, Haudenosaunee ("Iroquois"), Labrador Inuit ("Eskimo"), Innu ("Montagnais-Naskapi"), Nanticoke, Penobscot, Powhatan, Algonquian, and Yuchi. The collection is divided into two subcollections: Subcollection 1 is comprised of Speck's research material and correspondence, and Subcollection 2 consists of his manuscripts and related correspondence. The two subcollections were acquired separately by the Society, and were originally cataloged as the Frank G. Speck Papers (572.97 Sp3) and the Frank G. Speck Manuscripts on Native Americans (970.3 Sp3p) respectively.
