Illinois Genealogy Local Resources

Records are being posted online at lightning speed.

Still, vast collections of genealogy-rich records are available for research offline through archives, libraries, and societies.

Archives
Archives have online catalogs or published guides to their collections or of records housed elsewhere in the state. The Illinois Regional Archives Depository System (IRAD) includes seven regional depositories for the historical records of the counties of Illinois.

Libraries
Most libraries have online catalogs and resources such as maps, gazetteers, and other place-finding aids to help you locate information about Illinois. Local libraries may have collections of previous research, such as family and local histories and biographies. Those located near state boundaries usually collect records relating to the adjacent states.
