[Koha] Accession numbers, again

[Walls, Ian]

Elaine,


To add a new, searchable subfield to the 952 field, I think you'd need to:

1.  Modify the MARC Framework to include that subfield.  You'd probably need to use a symbol, since nearly all the letters and numbers are taken.  I tried to use # once as subfield, and it worked, but screwed up some of the displays.
2.  Modify the Zebra files
    a. ccl.properties and cql.properties to define a new searchable index
    b. marc21/record.abs to set up field mappings
    c. bib1.att to set up the attribute sets
3.  Reindex
4.  Modify the search script to allow searching on the new index
5.  Modify the search screen to display the option to search on this index

I may be wrong about the details of all this; I haven't done it myself yet, but that's what the code looks like to me.  Any Zebra experts want to correct me?

It might be easier to come up with a hack... if you accession numbers are less than 10 characters, you could wedge them into the 'stack' field, which I've not yet found a use for.  'more_subfields_xml' is also a possibility, since it's primarily used for UNIMARC installations.  I'm not sure if putting something in there for MARC21 would break things, though.

My thoughts on the matter, for what they're worth.

Subject: [Koha] Accession numbers, again

Sorry, I'm a little fixated on this, partly due to the archival and
historical nature  of our collection. I am desperately looking for a
way to keep barcodes and accession numbers separate, but searchable.

A while back I asked where to put accession numbers and it was the
general consensus to put them in the barcode subfield (p) of 952.  I
understand why you do this, because it is a) part of the item
information and b) can be searched discretely.
But this means you have to print out your own barcodes, a process I
would rather avoid given our inflexible*** networked printer (which is
on a different floor!)

My questions, then.
If I decide to use some other subfield (perhaps adding one in)  how
hard would it be for my IT wizard to create a discrete search for it
in the staff mode (similar to the barcode search)? I suppose the
process would have to be repeated for each update of the software?

I experimented with putting it into the public note.  This displays
well enough, but you can't actually search on this field, and a string
of numbers in a keyword search brings up roughly half of the items in
my test collection.  Clearly, that's not very useful.

Is there any chance an accession number subfield in the item record is
in the pipline for a later release?

Or, alternatively, I could use some advice on barcode printing
equipment.  Stand alone barcode printers vs a desktop laser printer?
Does printing them yourself make sense if you've got 10,000+ items?
Unfortunately, our numbering system is a little quirky using similar
runs of numbers with different prefixes for different types of
material, so getting a straight run  of pre-printed labels would be
awkward, and matching them up to the material would be a heck of a
job.

Thanks for any help!
