These are site reports on archaeological excavations in northern and western Pennsylvania and upstate New York. Most of the excavations were sponsored by the Pennsylvania Historical Commission (1929-1948). The reports include photographs, maps, and diagrams.

An anthropologist and student of Native American cultures, Elisabeth Tooker devoted a long career, much of it as a professor at Temple University, to study of the culture and ethnohistory of the Haudenosaunee of New York State. The Tooker Papers is arranged in six series, and contain her correspondence, subject files, research notes, and both published and unpublished papers.

An anthropologist, Pamela Wallace was the Head of Education at the Sam Noble Oklahoma Museum of Natural History at the University of Oklahoma. The papers include correspondence, research, works by Wallace, audio recordings, color slides, photographs, and videos of Yuchi Indians.

An archaeological anthropologist and linguist, John Alden Mason spent the majority of his career at the University Museum of the University of Pennsylvania. After receiving his undergraduate degree at Penn in 1907, Mason received a doctorate at Berkeley (1911) for his ethnographic work on the Salinan Indians of California, but his diverse interests in later years ran the gamut from Puerto Rican folklore to Piman languages and cultures (including Pima, Papago, Pima Bajo, Northern and Southern Tepehuan, and Tepecano), Mayan, Aztec, and Incan archaeology, and the languages of South American Indians. Mason was curator of the University Museum at Penn from 1926 until his retirement in 1958. The Mason Papers include both in-coming and outgoing correspondence, linguistic material, notes, and photographs relating to Mason's work in the southwestern U.S., northern Mexico, and South America. Centered on the years after Mason's return to Philadelphia in 1926, the collection covers all aspects of Mason's professional life, from reports on field work to answering casual questions referred to him through the University Museum to data and analyses on Piman and other languages. The collection also contains voluminous files relating to the Mason's editorship of the American Anthropologist (bulk: 1945-1948). Of special note are a series of class notes (1908-1910) kept by Mason for course work in ethnology, archaeology, and linguistics at the University of Pennsylvania under Edward Sapir and Frank Speck.

A Yale-educated ethnographer, William Fenton devoted most of his career to study of the Haudenosaunee. Receiving his doctorate in 1937, Fenton worked with the Bureau of American Ethnology for a number of years before becoming Director of the New York State Museum and professor at SUNY Albany. The Fenton Papers covers all aspects of William Fenton's professional life, documenting his varied positions as community worker for the New York Agency of the U.S. Indian Service, 1935-1937 (accounts, reports, correspondence); associate anthropologist and senior ethnologist in the Bureau of American Ethnology, 1939-1951 (includes notebooks, letters from the field); Executive Secretary of Anthropology and Psychology, National Academy of Sciences-National Research Council, 1952-1954; and Assistant Commissioner, New York State Museum and Science Service, 1954-1968.

The Anthony F. C. Wallace Papers include correspondence to and from 20th century anthropologists, ethnologists, historians, linguists, and psychiatrists and provides a wealth of resources for the study of technological and social change, American Indians, culture and personality, revitalization movements, the anthropological study of religion, and the cultural and biological bases of behavior. In addition to Wallace's correspondence, research notes, and drafts, the collection includes Wallace family correspondence and photographs, as well as Wallace's writings from childhood through recent years.
