As a center for historical and genealogical research, we have both an Archival and Microfilm Research Room for researchers. Our historical records date from the 1800s to the late 1900s, and include letters, photographs, maps, architectural drawings, and other documents received from over 70 Federal agencies and courts in Arizona, southern California and the greater Las Vegas, Nevada area. Please n

If you are planning a research visit with us, you are strongly encouraged to call in advance to request specific historical records for review.
