----------------------------Original message---------------------------- Kathryn, We use a post binder to hold encapsulated maps with flight line annotations that came with our collection of air photos from the Nfld. Department of Transportation. To supplement this, we have ozalid copies of other indexes, usually about the same size as a 1:50,000 NTS map sheet, as they are copies of ones which have been annotated by the provincial or federal government. These are filed in map folders in standard map cabinets. Despite this and because of the flimsy ozalid paper, they do get ragged eventually. We get the indexes and photos out for 99.9% of our users. The photos are in verical file cabinets, filed by flight line and photo number. Hope that this is of some help.
