James M. Crawford was a linguist who mainly studied Native American languages, including Cocopa, Yuchi, and Mobilian trade language. He came to the field of linguistics halfway through his lifetime after pursuing a career in forestry in the West and Southwest. After receiving his PhD in 1966 from the University of California at Berkeley, he returned to his birthplace, Georgia, where he taught in the Department of Linguistics at the University of Georgia at Athens. The collection is organized into seven series: I. Correspondence, 1964-1986; II. Subject Files, 1949-1987; III. Works by Crawford, 1962-1986; IV. Research NOtes & Notebooks, 1906-1988; V. Card Files, 1960s-1980s; VI. Course Material, 1961-1986; VII. Photographs, 1963-1978.

The Mary Rosamond Haas papers are extensive, including correspondence, research notes, field notes, texts, lexical slip files, audio recordings, photographs, reprints and more, covering more than 100 languages of North America and Southeast Asia. Of particular value are notes and audio recordings from fieldwork from the 1930s on Ditidaht, Tunica, Natchez and Muscogee, work toward pedagogical materials for Thai, and groundbreaking comparative studies of several language families of North America.

Audio recordings, primarily linguistic field recordings of Native American languges, removed from the James M. Crawford papers. The bulk of the recordings are in three areas: Alabama songs, stories, and fiddle music; Cocopa folklore, autobiographical stories, songs, and elicited words and sentences; Yuchi autobiographical stories, conversations, and elicitied word lists. Other material includes: Cherokee conversations; Chickasaw word and phrases lists; readings from a Chontal-Spanish dictionary; a Diegueño text; words lists and discussion regarding the Mobilian trade language (Yama); intermixed Mobilian, Choctaw, and Koasati word lists; Mohave songs, with explanations; a Navajo elicitation session, with interview and conversation; elicited Shoshoni expressions; Tolowa songs, Yavapai word lists and texts; and Yuki words and expressions. The small amount of non-Native American material in the collection generally consists of unidentified conversations, readings of English and Russian texts, and recordings of baby talk.
