Revised and expanded from a 1984 print version, this guide details Catholic records at 291 repositories in 12 Midwestern states that focus, at least in part, on Native Americans in the United States. These records date from 1704 and pertaining to 131 native groups in the United States. The entries are accessible in portable document format (PDF) and detail record types, dates, volume, languages of texts, native groups, prominent individuals, and the hundreds of Catholic dioceses, parishes, religious orders, and other organizations that created the records. By mid-2006 Marquette plans to expand the guide with entries for comparable records in the 14 Western states. This development was made possible by an $82,000 grant recently awarded by the U.S. National Historical Publications and Records Commission to survey Catholic-related records in the Western states in 2004-2006.
