If you don't have a ledger title
Look through the list for ledgers that cover the permit issue date you have
Select a ledger that corresponds to the region of Chicago for your address (i.e. North, South)
Scroll through the reel using the permit issue date to tell you when you're getting near to the permit you're looking for.
As you get closer to permits issued on that date, start using the permit number to zero in on the permit.
