----------------------------Original message---------------------------- Anyone on Maps-L that has had experience storing Sanborn fire insurance maps unbound in drawers, I would apprecicate comments. Recent legislation and new ASTM standards have put increased demand on our collection. Some years ago we microfilmed all our copies of volumes for the Cleveland area and purchased commercial microfilm for other editions. Patrons still need to consult the originals for accurate measurements and for original colors. Some of our copies are still bound others are loose sheets shelved in box portfolios. We are currently planning for a new facility and are debating storage in locked map cases v.s. restricted access roller shelving. The weight & thickness of the Sanborn plates make encapsulation & post-binding a less reasonable option although we have systematically been treating our Hopkins plat maps in this manner and it has worked well. Any comments about either method of storage would be appreciated. Maureen Farrell Map Librarian, Cleveland Public Library [log in to unmask]
