Hello, May I point you to http://www.langzeitarchivierung.de/index.php?newlang=eng, a German project how to preserve digital resources for the next centuries... As I know from the project guys, keeping the data stored is easy (you can move them from disk to disk, from image to image), but how to use the data in the future is really a big problem... Just my 10cc --Thomas P.S. I'm new on this list. It's common to introduce oneself?
