The pockets are made up for us in about 15-20 sizes with handkerchief roll edges on 3 sides, the fourth side left open so we can remove the map if we need to. We will then for scanning, etc, but not for reader use. As far as I am aware the Mylar allows the maps to "breathe" and even those that are sealed have not suffered any problems. We also have the maps flat in metal drawers, the cabinets for which are then housed in a room with temperature and humidity controls so that the environment stays within acceptable, stable limits.

If you do this, you can remove the maps for scanning later. Any further thoughts out there on this issue??? Dr. Dawn Youngblood, Ph.D Archaeology Edwin J.

However, at some point I would like to scan a number of these maps. Is it possible to scan encapsulated maps, will it hurt the scan quality? Any help that people can provide would be appreciated.
