I used to write a newspaper column (community kind of stuff) and I wrote one once on how our local library is the biggest value on your tax bill. (I tied it to paying the tax bill date.)
Man, when I think of how much money I'd have to spend if I didn't have the library ... I read books, I check out non-fiction titles (doing web writing is a big one for me right now -- tons of info out there in my library!) and the audiobooks that keep me sane while I exercise ... We do DVDs, too, though not as much as we should. I have never bought an audiobook, but I've listened to easily a hundre or more, in the past 10 years. Heck, I'd have to go with at least 200.
Love libraries!
