As one might expect, the University of Oklahoma has a tremendous amount of material related to the history of the American West. One particularly noteworthy collection in their holdings is the Duke Collection of American Indian Oral History. The digital version of this collection provides historians and others with access to hundreds of interview transcripts from the period 1967 to 1972. These interviews were conducted with Indians across Oklahoma regarding the cultures and histories of their different nations and tribes. Visitors can read these documents for insights into customs, social conditions, philosophies, and ceremonies. Begin by browsing through an alphabetical list of all the interviews, or visitors may also wish to perform a full-text search across all the transcripts.
