Very interesting. As you’ll soon read what makes this service really different is that it has no restrictions on the number of people who can borrow a book simultaneously. In other words, one copy-one use has been tossed out the window.
You’ll also read that beginning in the Spring newer titles will be available (opt-in) for library users to borrow for a fee (in addition to their library subscription).
