I swear, but cannot find it, that about two years ago there was a report by
somebody in the gov about the longevity of CDs. I remember that paper labels
are the worst thing you can do, but that if you eschew slapping a label on
it (and either using a sharpie or a printed label right on the CD), that
supposedly plain old CD (write once, read many times) were good for upwards
of 50 years. 

Sorry, I wish I could find that report again.
