Future of CDROM, DVD, etc.

I think we are confusing two issues here.
There is both a need for ready access to data, for which electronic media
are excellent, and a need for very long term storage of data essential for
future taxonomic stability.
The same situation applies with type material. I still insist on Canada
Balsam for mounting glass coverslips on type slides. The histology
department hate me because xylene is now considered 'dangerous' to health
and wellbeing. However, having dumped a large number of slides with plastic
coverslips which fell off (taking the specimen with it) and had more
remounted because the DPX crazed, I can see value in sticking with proven
technology, not cost and convenience.
I know that printing on acid-free paper is the best permanent long-term
storage media. My taxonomic work, written and drawn in electronic format
but printed on acid-free paper with permanent inks will (for better or
worse) be accessable for several 1000 years.
Nothing about the electronic industry inspires confidence in its long term
access capabilities. Even 9 track tapes deteriorate over short periods of
time unless they are regularly re-recorded and the tapes are rotated.
Access doesn't depend on having the machine but on access to spare parts to
keep them going. To use my example of the 78 record collection - I have a
turntable but I have a real hard job finding stylus's.
We recently cleaned the lab (only 15 years old) and found a whole heap of
taxonomic notes and slides left by my deceased predecessor. All immediately
accessable and useable. The computer disks were unreadable.
