Hi, Neighbor. Chicago: Chicago Urban League, ca.1939. The Hanna Holborn Gray Special Collections Research Center.
As the first page of this pamphlet states, "Some people have come to Chicago only recently, to work in our industries-- To make new homes-- To give their children a better chance. To the newcomers the Chicago Urban League says Welcome!"
This guide lists many of the key sources for researching the history of Chicago, but it is by no means comprehensive.
Please feel free to contact me with questions or if would like to make an appointment for a research consultation.
