Are you sure they just aren't placing it on some device and it looks like they aren't doing anything.

each library book has a little pocket, like the old days when they punched a card and stuck it in the book with the due date
they put a green card, about 3x5" in the pocket. They have the cards - if they dont put one in each book the alarm is suppose to go off
if you really wanted to steal a book all you have to do is check a book out, take it to your car, take the card out, go back in and stick the card in another book and walk out with it - so its a pretty dumb system
I cant figure out how it works. It looks like a green piece of card stock. How does putting a piece of cardstock in a book stop the alarm from sounding?!
