----- I remember witnessing an examination/final project presentation for a
degree in media restoration, during which the person presented a dark,
transparent red record (darker than the Victor Heritage) as proof that
records were also being made in "solid shellac". Neither the tutor nor the
external examiner protested. In the interval I sniffed the surface -
cellulose nitrate, obviously. I never told anyone aloud, but the event taught
me that if I were ever to hire someone - even someone with a degree - I would
present practical items for discussion during a job interview. There is such
a vast amount of media out there. And we would like people to have knowledge
about them.

Kind regards,

George
