[Koha] 090 Fields

[Albert P. Calame]

Hi All!
    I can't resist this one! I agree with Stephen that we should have a MARC
tag that Koha will use for "non-MARC linking" information.  The
philosophical underpinnings of MARC contain the convention that any tag that
contains a 9 in any position may be locally defined.

    As has been mentioned in earlier messages, the 090 field (actually most
of the 090's) have often been used to store local call number information,
by such august groups as the Library of Congress, OCLC, etc.  Additionally
the 900 field was originally defined to hold local call numbers in a
diskette transfer format called MicroLIF prior to 1991. (Post 1991 it
changed to use 852, using subfield 9 to hold price). Other ILS vendors used
999, 949, and 959 at various times to store the same information - following
the philosophy stated above.  Other 900 fields have been used for other
functions but these are the only ones I know of that have had any major
significance.

    Id like to suggest using the 930 or the 970 fields for any Koha special
needs. Neither, to my knowledge, has had any major use. We could define the
field or fields and subfields we need and publish this as part of our system
specifications. This would be appropriate use of the MARC structure and
would work in both MARC 21 and UNIMARC.

    Hope that helps.
