Open Library is an online library where you can borrow select books for free and read them on your screen. The process works like a regular library where you make an account and borrow available books. The borrowed time isn't very long, but you can reborrow them as many times as you like. If you forget to return them, the system will return books automatically. There are no late fees here. Open Library doesn't have every book, but they have a lot. If you don't mind reading off of a screen, this is a good place to find established books.
