Hi Pauline, Most of your questions can probably be best answered by reviewing this web site: http://www.cyberdriveillinois.com/departments/archives/irad/neiumap.html Towards the bottom of the page, click on Cook and the City of Chicago [it is a live link], and a discription of the holdings will come up.

Questions I would have are: What kind of genealogical info. would I be able to get from them? What kind of info. would I have to provide to them? Would I have to know the exact department to which I would have to direct my inquiries? There seems to be alot of them. What is the exact proceedure?
