Filling the boxes completely with photos helped prevent them from curling, but for the few boxes that were not totally filled, we inserted what the manufacturer calls "document spacers". These are simply pre-scored acid-free board stock, bent to shape, and placed inside the box to take up the free space. The boxes are stored vertically in standard file cabinets. The dropfront design of the boxes makes it very easy to retrieve photos. If anyone has questions, please feel free to contact me for details.

The Map and Imagery Lab keeps humidity at 50%, although the recommendations I've seen lately are for 20%.

But if he has the 9 x 9 size, they can easily be stored upright in archival-type boxes, or even in envelopes in a filing cabinet. Sue Haffner CSU Fresno
