Julian,
I know this is an old discussion but I just realized that saving a
biblio record longer than 99999 bytes result in a malformed leader.
Length of the record takes more than 5 characters and therefore
remaining characters in the leader are shifted to the right.
This cause the leader to have more than 24 characters.
I'm not sure of what have to be done. Should MARC::Record die when
encountering such a record? or should it force length to be 99999?
or should the record be truncated to fit the spec?
Has someone ever faced this problem? How did you handle it?
MARC::Record should proceed blithely on, like Admiral Farragut at the
Battle of Mobile Bay or the Light Brigade at the Battle of Balaclava.
The record can still be serialized as MARCXML, and large records are not
uncommon in the wild. As far as I know, the only way to handle it is to
use MARCXML instead of iso2709.

Jared
Ok, but the malformed leader is saved in the MARCXML, so it's displayed
in the MARC editor, and cataloguing plugins marc21_leader.pl and
unimarc_leader.pl won't work correctly.
Isn't there any workaround for this?
More than that, Koha is still generating malformed MARC records, and I
think it's a problem for an ILS which is MARC-compliant.
