Another Book sharing site
One of the unfortunate "features" of ebooks is that generally, they can't be lent to friends. With Kindle Books, if the item is "lending enabled", you can share it with others for 2 weeks. There are a couple of online communities out there that are trying to facilitate the lending situation: "Lending eBook". Registering with this site puts you in touch with a huge number of lenders. Worth a look. (Note: only US Amazon account holders can lend books, but anyone can borrow. The FAQ explains how to get a US account.)
