Yes, the library is great and I am an extremely heavy library user. Highly recommend you all take advantage of your local libraries. But there are also tons of free books available online that you can load onto your Kindle or iPhone or laptop and read 100% free of charge. Right now I'm reading Walden, and just got done with the Scarlet Letter. These things take on entirely new meaning when you read them again as an adult, by the way. I don't know why Hawthorne is wasted on high schoolers... we sort of pigeonhole these classics into "I read that in high school" and then we never read them again. What a mistake!
Anyway, Project Gutenberg has tons of free stuff there, classics and interesting weird old books. Check it out.
