Still can't understand why anyone wishing to borrow an item from the library would refuse to sign for it either as themselves or a repersentative of their ward/ dept. Perhaps an alternative solution would be to issue 'credit' cards to the users then they can swipe the card when they borrow the kit. The card would be under the control of a senior member of that dept. and they would take responsibility for its use. Actually, thinking about it it's probably a bit too hi-tec for most places.
