Chicago & Cook County Research

Online Resources for Chicago & Cook County

Below is a guide to online resources for Chicago & Cook County research. Our center has many of the corresponding records, but not all. The general rule of thumb is that we have all of the Chicago birth films, 1871-1915, all of the Cook County marriage license films, 1878-1916, all of the Chicago death certificate films, 1878-1947, many of the Cook County death certificate films, 1916-1947, all of the Catholic parish record films, and all of the available city directories. For more detailed information visit our resources page.

We welcome suggestions for additions to this list. Please email them to our website volunteer.
