First, the disclaimer that I'm coming at this from a technologist /
history of technology perspective.
The accessionable items you are describing are the data files that
comprise the individual images. Something added to the lexicon along
thee lines of "Image, Digital" would probably be keeping with the
spirit of Chenhall. That a scanner was involved in the production
process is only incidental. With contemporarily produced maps, census
data, and family photographs leading entirely digital existences, the
nomenclature should stay fairly flexible. The particulars of data
format (i.e. PDF or TIFF) should be in the description.
One consequence of digital items is that the traditional notion of one
catalog entry for one object kept in one location begins to fall apart
-- partly because the notion of an original also falls apart. Once the
data files are transferred into the museum's preferred means of
storage and backup, those files can be considered the new originals
and the CDs, Zip disks, etc. can be considered the equivalent of
crating that only served to get the files to you. Their storage may be
considered an unnecessary expense for objects whose physicality has
negligible curatorial value.
Ideally, the catalog should be able to point to multiple locations of
the single accession. That way, if you do print out a copy, it is just
a different format in a different location of the same accession.
However, some of the duplicates may just be work product and ephemera
not worth noting in the catalog. Also, with a good data migration
strategy, printing out as a retention strategy may not remove much
risk while adding to costs and filling storage space.
Consider though the possible existence of a piece of physical media
that is an exemplar of how certain types of data were distributed or
of notable provenance, then it would itself be an accessionable
object. If it contained instances of accessioned data, then you have a
situation where a single object represents a collection of items. For
a floppy or a zip disk, the extant "DISK, MAGNETIC" would suffice. A
CD or CD-ROM could be called "DISK, Optical" drawing from category 6.
The mind certainly boggles at the possibilities. If the data is what
will be researched, catalog to and care for that. If the physicality
of the media falls within the domains of the mission and scope of
collection statements, then I'd recommend cataloging to that.
