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. Located on seven state university campuses, regional depositories house and service those records of local governments which have been appraised as having long-term values and have been transferred to the Archives. 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
• naturalization records, including declarations of intent
• probate records, including wills and will records, case files, administrators' and executors' records, guardianship records, and inventory and appraisement records
• civil and criminal court case files, chancery court case files (including divorces), docket books and court proceedings, and insanity proceedings and records
• coroner's inquest records and inquest files
• miscellaneous county records, including almshouse/county home records and jail registers.
• township, municipal, and school records
• City of Chicago records, including nearly 35,650 previously unknown documents that predate the Great Chicago Fire of 1871. Holding include City Council proceedings files of 1833 through 1942, plats, atlases and Sanborn maps.
• Other Chicago records include election registers for 1888, 1890 and 1892 and ordinance records spanning 1837 to 1916.
