Kindle Owners’ Lending Library

Amazon:

With Prime, Kindle owners can now choose from thousands of books to borrow for free including over 100 current and former New York Times Bestsellers — as frequently as a book a month, with no due dates.

You need to own an actual Kindle, though, not just use the Kindle app on another device. And, publishers need to opt-in, and none — zero — of the big six have.
