Dear Iain & group,
  I have been reading this thread for the past several days but Randy 
(husband) was in Las Vegas for NAB (National Association of Broadcasters 
convention), and I was waiting to ask him what he thought. (Some of you know 
that we did the David Rohl DVDs, and a large part of that project was 
scanning 200+ slides from David's personal collection from various 
archaeological dig sites.)
  Randy said to tell everyone that what I have been reading is also what he 
has heard: that the current thinking re: technology is that the CDs will not 
last much beyond 50 years, *but* that nobody really knows this for certain 
since the technology is so new. He also said to tell you that supposedly, 
the rewriteable form of CDs should last longer. (The 'rw' format.)
  He also agreed with the poster who said to use sharpie pens or have the 
labels burned onto the  CD, rather than using paper stick-on labels.
  He also said that it does not matter whether you store them vertically or 
horizontally.
  I think that about covers it. If you think of any further questions, this 
is his specialty, so just post them & I'll ask him right away.
