If you live anywhere in CA, you can get an LA library card which gives you up to 10 books at a time for up to 3 weeks. My local county library system is smaller, but also gives options as well.

Additionally, for $35 a year, anyone in the US can get a Philly library card, and has an amazing ebook library. Again 10 books at a time. http://libwww.freelibrary.org
