The University of Oklahoma's Western History Collections were established in 1927 to gather and preserve records for scholarly research in anthropology, Native American studies, Oklahoma history and the history of the American West. This guide describes manuscript collections which include papers from pioneers and later prominent citizens including businessmen, educators, Native American leaders, historians and anthropologists. The manuscripts cover a variety of subjects such as cowboys and the cattle industry, the Five Civilized Tribes, frontier life, missionaries in Indian Territory, the oil industry and the history of transportation in the West.
