Brooklyn Public Library is now live, with a tiny ePub-only selection as in other 3M collections, but different books. Click here:

If anyone who lives in New York, or has paid the $50 annual Brooklyn Public Library fee, wants
All In: The Education of General David Petraeus by Paula Broadwell, you got it.
P.S. Further checking shows that almost all the books have long wait times, which is a little unusual for BPL. So if you want Broadwell's tome, you got it -- in 145 days. I'm not sure if patrons are waiting in a queue, or waiting to prevent library borrowing from cannibalizing end-reader sales.
