If you have a library card, you can go here:
http://library2go.lib.overdrive.com/...en/Default.htm
From a drop down list, you can pick out your local library where your card is registered and then browse their database by authors, titles, subject, all kinds of stuff - and can download a library loan for up to 21 days. For some books you might have to place a hold like you do at a physical library to get in line for it but there are thousands of books out there to borrow. This started about Sept of last year and is really neat! After you have read the book, you just push the button to electronically return it to the library - or if the expiration date comes first, it will automatically be returned and you would need to check it out again, great invention!!!
