A recent article in the Chicago Tribune highlights the availability of historical digitized issues of the Lake Forester Newspaper (Lake County, IL) now online! The issues span 1899-1940 and should be of great interest to anyone with Cook County connections. 

1899 issue of the Lake Forester newspaper

Lake County borders Cook County on the north side and with this 40-years span of historical newspapers, there is a treasure trove waiting to be explored for Cook County citizens.  You can access the issues on the website of the Lake Forest Library and you can read more about the project at the Chicago Tribune website.
