I like the community bookcase idea

A friend sent this link to a community bookcase with more explanation here (Google translated). I’ve seen these in a few places including my local laundromat. They seem to tend to come to equilibrium with a hapless collection of religious texts, romance novels and old scifi. Luckily for me, I like scifi, but since I rarely go into the laundromat expecting to encounter a community bookcase, I rarely have anything to offer.
