Central Region Collections Overview
Local government records include those from county offices such as the Auditor, the Clerk, the Treasurer, the Board of Commissioners, and from municipalities, school districts, and other service districts. Only a small percentage of the records created by these offices are transferred to the State Archives. They are selected for their value as legal and historical evidence of policy development, implementation, and effect. The transfer of records to the State Archives is an ongoing process. Some historical records remain with their originating office pending future transfer to the Archives.
Major subject areas of the records in custody include:
Genealogy - Genealogical records include birth and death records from the turn of the nineteenth century, marriage records ca.1867-1997, naturalization records, probate records, and a host of additional records such as pre-statehood county censuses, and schoolchildren censuses ca.1890-ca.1932. Completeness of these records in the Archives' holdings varies from county to county, but the Archives staff can assist researchers in determining the appropriate location of the information, if it exists.

Land Use/Property - Land use and property records include patents, deeds, mortgages, tax assessments and rolls for both real and personal property, timber cruise ledgers, mining claim records, plat books, and water rights records.
