Perhaps the biggest concern of companies in this situation is longterm
access to the information. At least if it's on microfiche, all you need is
a light source and a magnifying glass. Once encoded on a CDROM, you must
be assured of having computer-based access for a long time. Since fiche
lasts perhaps 50 years, then the company must be assured of having a
computer to read the pages for at least that long. The good news is, that
page scans are a very basic algorithmic problem, and no matter what the
computer of the future (or next week!) looks like, there should be no
problem reading the data. If, on the unlikely possibility that it looked
as though CD technology were disappearing, that data could easily be
written off digitally to another storage medium.
From a time and cost perspective, perhaps the greatest difference (if we're
talking about a lot of pages, as in most such archives), the time to snap a
picture is much less than the time to scan. On the other hand, the data
are in a much more malleable condition. I tend ot come down on the side of
digitizing where it makes sense. If the company wants to do the job twice,
they could film it now, and then digitize from the film later, once they
were comfortable with the technology.
Hope this helps — Rich Bowers
