Have you tried borrowing a mildly popular recent book from the library? There's often a digital queue of 20+ people with reservations.

There's plenty of incentive for most people to buy the real book rather than wait for the queue.

(I've also found libraries a useful way to discover lesser-known authors, since you can quickly sample/browse books on the shelves. But they wont have all of the books published by those unknown authors.... so I end up buying/ordering other things by them)
