Thanks much, Richard.

Lots of new and relevant information in the document to digest and
follow-up on--  especially the affordable optical disc testing
options which might help signal when its time to duplicate one's
discs.  I'm thinking there might be services where one can send in
some sample discs every year to get tested on the top-notch testers.

So, today, the British Library Sound Archive would prefer to receive
new collections of sound recordings on numerous mirrored drives?  Rob
