Kindle owners with an Amazon Prime membership now have even more reading options as today Amazon introduced a free lending library for Prime subscribers. The virtual library boasts over 5,000 books and can only be read via actual Kindle devices, not smartphones or computers with Kindle apps. One book can be checked out per month, though unlike your city library there is no due date for when that title must be returned.
If you're worried the recent bestsellers you've been meaning to pick up for your book club won't be included in the library, Amazon reassures that over 100 of the books are current and past New York Times bestsellers. However, books from the six biggest publishers, Random House, HarperCollins, Penguin, Macmillan, Simon & Schuster, and Hachette, are not participating in the library due to royalty concerns.
