Chris and Doug,
Is it a dream because of the maverick nature of
biologists, or because of something else? Perhaps
if all could see the advantage of a system...there might
be a way to find agreement and a solution.
And, Doug, it may take longer to initiate a system,
that is, to code in all the information,
but would it be quicker and faster for a new person
coming on line to either find the specimen or
retrieve the data ONCE THEY ARE IN THERE?
Even a competent museum curator may have to take
a few minutes to find certain specimens in a collection,
especially if he/she is new to the collection.
My late father was the former curator of Coleoptera
at the Cal Acad. He kept the whereabouts of
millions of beetles in the CAS collection in his head,
the names of specialists who had made special or
specific requests, etc. It put Dad in a unique position
of knowing all, but it also created a problem for the
next curator, Dave Kavanaugh. Dave had either to
learn what my Dad knew, or submit the collection of
a computer reference.
