This is so helpful. I really was interested in the oldest papers so this is good to know where they are (Libertyville). Thank you! I will be in Chicago for other reasons but hope to get up north in my free time, for family history research.
I have been reading about both the Waukegan gen. soc. and Lake Co. gen. soc. and wish I could hear anyone's descriptions about the collections - what do you like best about both? I have seen their lists of materials. It all sounds great and am really looking forward to being up there.
