Our geology Dept. donated 36 boxes them to us. They were flown for USGS in the '70s and '80s for quadrangle mapping in Missouri, and I guess when they were done with them, they donated them to the university. Since we don't have the old machine they used to view these things, I'm planning to scan them and make digital copies. But first I'm wondering how unique this collection is. Thanks, Jim
