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 rolling hills between the Mississippi and Missouri Rivers are home to the Midwest's Hawkeye State, faithfully cataloged in the WPA Guide to Iowa. Stressing the agricultural roots and varied crops grown throughout the state, this guide includes many pictures depicting the lives of Iowa farm workers in the 1930's.
