I was going to suggest that digital scanning would seem to be the
ideal solution to ephemera preservation until I considered the life
span of computer file formats and their associated memory devices.

Does anyone have any notion of how long the distributed information
we keep on the Internet -- say, in 'digital museums' -- might last?
That is, how long might it be before it's all obsolete and we can't
get to past generations of scanned material, either audio or visual?

So, perhaps the best idea is to copy stuff onto acid-free paper and
hope for the best.  (But scan it and upload it, too.)
