Open Arizona is a collection of open-access titles from the University of Arizona Press, part of the Humanities Open Book program, jointly sponsored by the Andrew W. Mellon Foundation and the National Endowment for the Humanities. The collection consists of 32 critical works from the press (including some that had gone out of print), but which are now available digitally. The topical focus woven through the volumes touches on the importance of the Southwest U.S. to understanding modern American life, including subjects such as government policy, Indigenous communities, and the experiences of Mexican-Americans. A prime example is the book Missionaries, Miners, and Indians: Spanish Contact with the Yaqui Nation of Northwestern New Spain, 1533-1820, by Evelyn Hu-DeHart, which explores the Yaqui Indian resistance and documents their complex relationship with Jesuit missionaries during the Spanish colonization of Mexico. Visitors can read any of the titles in the collection in an online reader (click "Read Text" on any title page) or download for offline use (click "Download Text"). Open Arizona also includes a set of 10 "Essays" (which are linked in the menu at the top of the page) written by contemporary scholars, which provide readers with insights and reflections about the books in the collection. Readers can also click "The University of Arizona Press" in that menu to learn more about the press, its work, and other publications.
