Hard or soft? how do you want it?
Seen a few remarks in various threads about people waiting for paperbacks to get books. Should that be a criteria for book club selections? Do a lot of people have aversion to paying more for hardcovers?
On one hand, that would limit the club's ability to jump on a hot new book. And some books don't make it to paperback. But if it meant more people participating, might be worth it.
