Thanks for the comment. I think that Indranil Das Gupta was proposing a
direct intervention at MySQL level -- that's certainly what I am looking for.
I'm uncertain as to _where_ the limit of 99999 bytes applies; it's the
formal definition and MarcEdit probably respects that (I only have a very
old version, and know very little about it, so cannot properly verify) but
I don't think MySQL has any hard limits, nor has Koha unless I'm mistaken.
Not at all sure about Zebra...
I've just looked at one rather large record
<http://opac.navalmarinearchive.com/cgi-bin/koha/opac-detail.pl?biblionumber=23866>
but it has only 94 items (and MarcEdit swallows it, but it's only 31242
bytes, so nowhere near "the limit."
We're looking at quite a few serial runs of over 100 years of monthly
issues! already in ODS format so a direct import into MySQL might be the
fastest way. I keep pushing this project to the back of the queue, but will
have to face it sooner or later.

You could try compiling to MARCXML, but I don't think the file importer
for Koha can handle MARCXML.
The closest I got to creating a massive MRC serials record was to use
YAZ-MARCDUMP (http://www.indexdata.com/yaz/doc/yaz-marcdump.html) to
convert the big MARCXML record into MARC21. It seemed to compile but it
was hard to tell. It wasn't valid MARC after all, and I couldn't exactly
look at it in MARCEDIT.

If you have details, please make them available. We looked into this
(again after MarcEdit attempts), but ran into problems (from memory,
more_subfields_xml) ... and we've got about .25 million items to add ;=}
Thanks -- Paul
