Researchers should be aware that many Arizona records pre-date the county formation due to mining claims, grants, territorial court cases, etc.
Current contact information for each county can be found through the State of Arizona website <www.az.gov/webapp/portal>. The Arizona State Library, Archives, and Public Records website has links to “Accessing Arizona Public Records” with public record and county information.
