It was free. I've never had to pay for any information coming from an Illinois FOIA request.
Have you thought about distributing the data, for accessibility and reproducibility? As well as save the taxpayers a little bit of dough in case someone else wants to request the same data.
You might want to try postal address lookup/verification software to fix the addresses.
That's interesting. I've often had to pay small to medium-sized amounts - always reasonable, I might add - for the price of producing said information.
You can often request that the FOIA officer waive the fee so long as the public's interest outweighs the burden to collect and redact the info. That's almost certainly what happened with my IL requests.
I didn't even know about FOIA request until this post thanks for write up
