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.

Montana, one of the Great Plains states, is finely portrayed in its WPA guide. Originally published in 1939, the spirit of the Wild West shines throughout this guide to the Treasure State. During this time period, the population of Montana was rural and cities small, with most of the economy tied to the land, mining, or cattle. With 10 hiking trails outlined for Glacier National Park alone and 18 driving tours throughout the state, this book is an excellent resource for history and nature buffs alike.
