During the 1930s in the United States, the Works Progress Administration developed the Federal Writers' Project to support writers and artists while making a national effort to document the country's shared history and culture. The American Guide series consists of individual guides to each of the states. Little-known authors many of whom would later become celebrated literary figures were commissioned to write these important books. John Steinbeck, Saul Bellow, Zora Neale Hurston, and Ralph Ellison are among the more than 6, 000 writers, editors, historians, and researchers who documented this celebration of local histories. Photographs, drawings, driving tours, detailed descriptions of towns, and rich cultural details exhibit each state's unique flavor. The WPA Guide to Oklahoma is filled with descriptions of Native American life in the region, accompanied by many photographs. From Black Mesa to Cavanal Hill, this guide to the Sooner State takes the reader on a journey across the state's vast and varied landscape. Also, notable in this guide is an essay by prominent historian Edward Everett Dale entitled "The Spirit of Oklahoma."
