This hit on the problem exactly although I didn't cite it in the original
posting.  One of the decennial census archives (1960?) was nearly
completely lost by the U.S. Government Census Bureau for this very reason.
It had not been transferred as "legacy data" into a newer system.
Fortunately it was caught just before the hardware (tape drives?) and
software used to read it was completely "sundown."

Those having digital archives of images will have to ensure the legacy
images are transferred into newer formats on newer media as the existing
ones sunset.  This part scares me with caretakers such as the National
Archives and other *huge* repositories which are notorious for too much
data and too few people keeping track of it.  In addition, there could also
be degradation moving an image into a new format.  To wit, try saving a
"jpg" image as a "BMP" or some other format.  Between certain formats
information is lost due to the differences.

I know most of the list readers are still using "celuloid" (actually its
replacement), however this is more food for thought, especially as Olympus
seems to be pushing hard (or at least was pushing hard) in the digital
direction.
