----------------------------Original message---------------------------- The Map Collection at the Free Library of Philadelphia has a growing collection of regional aerial photographs. They are larger than most, measuring approx. 2.5'x 2'. I've had them encapsulated with a large end strip for possible binding. I've gotten an estimate for building a storage facilitiy and for custom binders and it's expensive. Any thoughts out there on alternative stoage methods for some this big? At this point there are over 1,000 photos. What have other locations done? Thanks for any suggestions. Rich Boardman Map Collection-Free Library of Philadelphia
