I have just checked on the policy regarding folks who book a group room but don't show up. In fact, we have a 15 minute grace period after which time the booking is forfeited and then the room is available on a first come first served basis. We don't have the staff to patrol the rooms to see if they are booked but not being used, but if you see an empty room as you describe please come and inquire at the circulation desk. I'm not sure if our system would allow us to impose penalties if a room key isn't signed out since at that point we have no patron information but that is an interesting idea.
By the way, the purpose of the rooms is for group work NOT quiet study and we will be discussing policies and procedures to ensure appropriate use of the group work rooms in future.
