I'm no expert on MARC, but the plan is to make it a full MARC record.  I
don't have the code yet for actually writing out the data as a MARC
record, but that really is trivial.

I've been doing this for some time.  My concern with this is that I've
generally had to fiddle with the importer to get holdings records to work
right, as everybody seems to put info in different places in the MARC
record.  Also, some things like Koha's "itemtype" which is pretty critical
to the way Koha stores data, are hard to extract automatically out of any
given MARC record.

The way that I've been doing it is that the librarian's save the MARC
records to their home directories on the server, and then go through and
edit each imported record individually to make any necessary changes.

When importing MARC records for an entire collection (when a library is
switching from another program to Koha), I tweak the MARC import routines
so that the data is imported correctly.  

This is why I'd like to see Koha adopt MARC as a base data storage format,
to make importing MARC records from other sources a little less painful.

You're right.  Should have been 260 c (Date of publication, distribution,
etc., may contain multiple dates (e.g., dates of publication and
copyright)).
