As a historical foundation and part of the collecting community in Arizona, our goal is to selectively collect, preserve and make available historically relevant material to current and future generations of researchers. The focus now rests on internal strengths identified through an independent audit process of the repository’s holdings. These strengths include Arizona business, law and politics. holdings include over 135 manuscript collections, 50,000 photographs and ephemera, books, artifacts, film, videos, maps, oral histories, political cartoons, microfilm and several distinctive card catalogs
