I don't know, but I'm having a grand time looking.  Here is a document published
by the Library of Congress in 2003.  "LONGEVITY OF CD MEDIA:  RESEARCH AT THE
LIBRARY OF CONGRESS"  It's supposed to be in PDF format, but I can't seem to
access that version.  Maybe somebody at LOC can point the way.  In the
meantime, I found an HTML version by following this link:
