Re: Life expectancy (n.b.) of media

The most useful recent reference on this general topic is
Michael Lesk, _Preservation of New Technology_ (Washington, DC: Commission
on Preservation and Access, Oct. 1992), 17 pp. + 2p appendix. $5 from the
Commission at 1400 16th St. NW, Suite 740, Washington DC, 20036-2217.

One of his main points is that technological obsolescence is more of a danger
than medium obsolescence: e.g., the punched cards can be made to last a very
long time but the readers for them are now almost impossible to find.
Similarly with magnetic tape, 8" floppies, and the like. We can keep the
tape for measurable times, but finding a 256-bpi tape drive is not likely.

(The third preservation issue for electronic materials, one important to me,
is intellectual preservation; or authentication that the bits read today are
the same as those encoded, onw hatever medium, yesterday or 100 years ago).

I know this doesn't answer M. Lenoble's question directly, but perhaps it
will help.

Since no one has yet replied more definitively about why Bill Watterson
calls his comic strip "Calvin and Hobbes," let me report what he told the
Cleveland Plain Dealer Sunday Magazine a few years ago. (He is, one hears,
pretty shy about interviews and militant against merchandising, so maybe
this is less common knowledge than I would have thought.) The boy and the
tiger are indeed named for John Calvin and Thomas Hobbes, so I remember the
interview reporting, but I also recall him denying there was any more
significance to the names than the fun of making what, for comic strips, would
already be a pretty arcane reference.

The proceedings of the 3rd Joint Technical Symposium, Archiving The
Audio-Visual Heritage have just been published. (I've just received mine)

ISBN 1 873902 02 6 Editor George Boston 192pp illus.

It should be available from the National Archives, Audio-Visual Section
and the Library of Congress. Sorry I don't have a price.

It has an excellent explanation of the processes involved in "Vinegar
Syndrome" and the degradation of Polyester based stock. It also has
sections on optical media and cd-rom preservation research.
