Currently, I'm writing a story that I need to do some research for. The story takes place in early 1960's Chicago, and revolves around a police officer who has received several phone calls for the previous few months. After one of the phone calls finally reveals the trace of the calls to have been very close by, the officer decides to go to investigate who has been calling him by himself.

Anyway, what I would like to know is if the people on this wiki know of any primary sources or documents that could help me develop the early 1960's of Chicago. I have found some documents so far, but if anybody else knows of any possible resources about the orphanages, buildings, and the lifestyle of the people in Chicago during that time, I would be very thankful and formally thank each of the people who recommended a document/video/primary source to me at the end of the story.

A couple of the sources I have viewed:
