Kindle Post US: Kindle Books Now Available at Local Libraries. This is both very cool, and very smart business.
The checkout process is surprisingly easy. Click a button and you’re sent to Amazon, where you can click another button to send the book to your Kindle. You can also download the book to transfer via USB, but otherwise it’ll come through via WiFi.
Amazon will back up all your notes and highlights for a book, so if you check the book out again they’ll come back as if the book never left your device. Perhaps more interesting is that there’s a very quick “buy” link for all the books that you borrowed, which is sure to drive sales.
