People frequently take all the good books, all at once, and don't return them.
Someone just emptied out half of it yesterday, and I don't even think they were picky. They just took a whole shelf of books.
It's such a crappy thing to do, and there's nothing that can be done to stop the bad actors.
Where I live actually has the opposite; there are ~6 within a mile, and they're usually completely full. People are always dumping huge collections into them, to where I never even have the chance to give back myself.
I don't know what makes it different here. But it is possible for them to work without safeguards.
And yet they'll have to pry my OpenRC, cronie, and sysklogd from my cold dead hands...
