Re: obscure arcane knowledge

My sister heads up the digital library initiative for the University of
Maryland. They maintain a database of the serial numbers on each backup
CD's core. On most of the archival discs, the clear piece of plastic in the
center of the disc has a discrete serial number.

She doesn't use writable DVD's because of the indecision on standards and I
think her archival CD-R's are about $10 a piece!

FYI.
