When I took a preventive conservation workshop at the Smithsonian in 1987 the conservators recommended board lumber as opposed to plywood for storage areas. This is because the adhesives used in plywood and particle board give off formaldehyde fumes, which are undesirable from a preservation point of view. They also suggested that the board lumber be sealed with shellac. --Helen Glazer Exhibitions Director and Collection Coordinator Goucher College, Baltimore, MD, USA [log in to unmask]
