Illinois Historical Records Survey Project
Chicago: Historical Records Survey 1937-1941
The Historical Records Surveys were done during the Depression to provide employment to needy unemployed historians, lawyers, teachers, and research and clerical workers. It was organized to compile inventories of historical materials, particularly the unpublished government documents and records in local archives. Some of the Inventories have been digitized and are available online.
These surveys of the holdings of County archives were done throughout the country, but many were never finished. For Illinois, about 34 or these surveys are available online. The first link above (at Illinois Reference Works) lists all the counties that have online surveys, with links for each. However, the online reader there is difficult to use. The second link, at Internet Archive, contains copies that are more usable. However, a user needs to open each volume to see what county it covers.
