Just following up on the 090 problem ...

Actually, that's just a bit of a misnomer, Albert, as we're talking about a
MARC field tag to be used within Koha! ;-) What we all mean, I think, is a
tag for non-AACR2-prescribed data, like the format info Koha was storing in

I remember downloading records from at least one of the University of
California libraries that had detailed holdings and other (I guess they
were) system/library specific coding and notations. Seen a lot of the 949
ones. One might experience minor problems when downloading copy if such
systems became more widespread.

I like your field suggestions, Albert, although David Bigwood pointed out
that one could use the 655 for format in the way that Koha is using it and
stay within the prescribed fields/tags.
Albert's suggestions are clear for MARC21 and for UNIMARC (at least as far
as the online conversion guidelines UNIMARC-->MARC21, and the historical
field use list I have from LC, show).
Do any European Koha folk know if there would be conversion problems with
930 or 970 based on experience with other ILS?
If Koha goes forward with a 930 or 970, someone might want to submit the
info to the MARC Development people at LC and see what they think
(especially to see if they know about other systematic uses of those tags).
It never hurts to know.
