Following the recent release of the ad-enabled Kindle with a $25 price cut, Amazon today announced yet another potential cost saving feature, Kindle Library Lending. Launching later this year, this feature will allow Kindle customers to borrow Kindle books from over 11,000 libraries in the U.S. just as you would do with physical books. The new feature works with all Kindle devices, as well as Kindle reading apps, so even if you're not invested in the hardware, you can still 'check out' an eBook.
