"The Open Library website was created by the Internet Archive to demonstrate a way that books can be represented online.
The vision is to create free web access to important book collections from around the world.
Books are scanned and then offered in an easy-to-use interface for free reading online. If they're in the public domain, the books can be downloaded, shared and printed for free. They can also be printed for a nominal fee by a third party, who will bind and mail the book to you. The books are always FREE to read at the Open Library website."
