Wild. I'm in the same bracket, and I'd say half of my friends and co-workers in the bracket are library people. It's not a matter of going to the library for information that is really available for free on the internet. I'm there for the free books. If you read 40 books a year and are patient enough to ensure the sometimes months-long waitlists for new and popular books, using your local library could easily save you ~$400 per year.
