----------------------------Original message---------------------------- We have one hanging file that we use for the Alaska Topo series. It is a sort o f large tub with hanging folders for maps inside. Maps tend to fall to the bott om of the tub if it is not full. I think it is better for maps to be flat rathe r than hang from files from a preservation point of view. Our Alaska series is not used much and the tub is full so the hanging files have not presented a pro blem yet.
