Re: [ARSCLIST] electronic reading of physical media, was: Preservation policy question

A challenge, yes, but with the way so-called "3D" imaging on computers 
has changed over the past ten years, I can imagine that it could be 
read in three dimensions in a few more years.. Like the electron 
microscope ikmages we ahve seen for so long, just being able to 
transmogrify them into audio shouldn't be impossible.

As a science fiction reader who saw communications satellites invented 
in fiction before reality, I can imagine many things... and there are 
some things I may live to see. This all speaks to saving the originals 
while archiving the best we can today.
