ILLINOIS
Illinois State Archives www.library.sos.state.il.us/departments/archives/databases.html This data-packed site now includes databases of public-domain land tract sales and Illinois servitude and emancipation records.

Cook County Clerk of the Circuit Court
cookcountyclerkofcourt.org/nr

INDIANA
Indiana State Digital Archives indianadigitalarchives.org
The fruit of 15 years of work by Friends of the Indiana State Archives volunteers, this site now boasts nearly 2.5 million searchable records, with more being added. The latest addition is a database of more than 213,000 Hoosier Civil War records.
Allen County Public Library

Although renowned for its general genealogy collection, this library in Fort Wayne is also a treasure trove for hometown and home-state researchers. Statewide databases include county courthouses, WWI deaths, African-American settlements, orphans and pre-1882 deaths.
