When researching Chicago address changes over time, genealogists might discover a few hurdles. In 1909 and and 1911, some Chicago house numbers were changed. Streets have also been renamed over the years. So how do researchers find correct addresses today for Chicago addresses in the past?
Chicago History Museum LibGuides
The Chicago History Museum features essential resources for Chicago address change research. But historians, genealogists, and other researchers were dismayed when their excellent guide to this topic disappeared. Also gone were PDF versions of three rare printed volumes supporting this research. Online searches did not reveal equivalents at CHS or elsewhere online.
Good news! Chicago History Museum now delivers this information in a LibGuide. (LibGuide templates help librarians share and update information more easily.)
Building and House History LibGuide
Chicago History Museum’s Building and House History helps users get started. This LibGuide provides information on Chicago building landmark status. Links to the Cook County Assessor, the Historic American Buildings Survey (HABS), and Sanborn maps are also featured.
