Arizona County Resources
This entry was originally written by Dwight A. Radford and Nell Sachse Woodard for Red Book: American State, County, and Town Sources.
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. The Arizona State Library, Archives, and Public Records website has links to 'Accessing Arizona Public Records' with public record and county information.
