Currently, the only default matching rules for MARC21 are ISBN and ISSN.

However, I'm sure that many people would profit from having a 999$c "Koha
biblionumber" record matching rule as well. 

1) If you export your bib records to do some global/batch changes with another
program (like MarcEdit), you can use this rule to replace the existing bib
records with your modified records.

2) With my upcoming OAI-PMH harvesting feature, if you add a OAI-PMH repository
with this rule in the configuration, you'll be able to automagically match
updated records with the original records that you imported via OAI-PMH (the
magic is that I check the incoming unique identifier against records in Koha,
and if there is already a bib record in Koha matching that identifier, I write
the biblionumber for that record back into the incoming record so that they
match. It sounds convoluted but it works well).

3) People might have other ideas about this as well.
