The biggest oversight when my library was built was that they only put in one Quiet Study Room.
It is constantly in use, and constantly in demand. Because people want a quiet place to close the door and spread out, we do what we can to accommodate them - or they do.
When otherwise not in use, we let people use the Conference Room as a quiet study room. We also have a Local History Room, and many people decide to go in there and close the door.
And this is the root of the latest controversy in my library. Our Local History Room contains our local history resources, and, by library policy, is Open To All* patrons whenever the library is open. Which means anyone can go into this room, and if someone is already in there, they have to share.
However, we've recently had a spate of patrons closing the door and telling other patrons the room was reserved, and they couldn't come in. This confused patrons and irritated staff, so we finally had to put signs up on the Local History Room door to very clearly spell out our policy.
As you may know, I have a reputation for taking down signs, so I wanted to make sure this sign was clear and effective - and I think it is. Since it went up, we haven't had any problems. People still go in and close the door, but no more intra-patron intimidation, and that is a good thing.
Oh and by the way, I hung a sign both on the outside as well as on the inside of the door - that way when someone does close the door, they can't claim they didn't see the sign.
