The Amelia Susman Schultz Papers primarily contain original ethnographic fieldwork and related research at Round Valley Indian Reservation in California conducted during the late 1930s, especially with Konkow Maidu, Wailaki and Nomlaki Wintu people, and between 1948 and 1950 in Brienz, Switzerland. The papers include field notebooks, printed materials, research notes, one audio tape, draft manuscripts, sketch maps, and correspondence.

This collection includes manuscript and photocopied material of Lucy S. Freeland, in which she records the stories told to her by Thomas Williams and Lena Cox. Also included are offprints from "The Hudson Review" of translations of these myths by Jaime de Angulo. There are also documents prepared by Berman in preparation for the publication of these myths in "Freeland's Central Sierra Miwok Myths" (1982).

The linguist Harvey Pitkin has worked on several of the indigenous languages of Northern California, with a particular interest in Wintu, Patwin, and Yuki. A student of A. L. Kroeber, Pitkin was a member of the Department of Linguistics at the University of California, Berkeley, and later at Columbia University before his retirement in the late 1980s. The Pitkin Papers contain materials recorded or accumuluted by Harvey Pitkin during the course of his study of American Indian languages, including not only his own fieldnotes and research on Wintu and Yuki, but originals and copies of notes, notebooks, and slipfiles by A. L. Kroeber, A. M. Halpern, John P. Harrington, John Alden Mason, Paul Radin, Hans Uldall, Donald Ultan, T. T. Waterman, and others. These include important information on Atsugewi, Kwakiutl, Luiseno, Pomo, Wappo, Yahi, and Yana, and include some data on the consultants Ralph Moore (Yuki) and Ishi (Yahi).
