It includes background information on the land and people of Oklahoma (geology, climate, topography, vegetation, animals, prehistoric peoples, French explorers, Indians, American explorers, early settlers, and the dust bowl and the Great Depression), governors of Oklahoma, county names, state government, famous Oklahomans, tourism, women, blacks, and minority groups. Maps and charts are used liberally throughout the document to illustrate the text. The document concludes with a bibliography of materials on Oklahoma, published between 1970 and 1980. (DB)
