it’d be a shame for books like that to disappear from the library. or not.
Lol - when my kids were young and we went to the library, they would pull books out and every book that was full of garbage, occult, etc., when I slipped it back onto the shelf I would accidentally push it to far back and it would fall off and land between the wall and the shelf. Nobody would be able to take the book out - I still feel badly about it to this day. NOT.
And if you can't get them out the door because of the security sticker in it, give them a new home in the "How to rewire your house" section of the library or some other obscure area.
I like that plan.
