Just to show that there is always another "on the other hand": We are on the top floor, with windows. Which puts us under the leaks from backed up roof drains. We used to struggle to keep the light from the windows off the rare books until we moved them to a windowless area. The light still fades Hollinger boxes, but that doesn't bother me too much. Maybe I'm grumpy because my office looks up the Potomac rather than overlooking the city. Jon Reynolds
