ILLINOIS STATE ARCHIVES
Illinois Regional Archives Depository (IRAD) System
The State Archives administers a system of Illinois Regional Archives Depositories (IRAD) to manage the archival records of local governments. Local governments which have transferred records to the regional depositories include counties, townships, municipalities and school districts.

County records include:
- county board proceedings files and meeting minutes
- records of births, deaths and marriages
- land deeds, mortgage and tax sale records
- assessors' and collectors' tax books
- poll books and voter registers
