It is not possible to hide eg field 600 (and several more) in the editor,
because addbiblio.pl line 346 implements a special case (based on bug 2206,
according to a code comment there): If there is a subfield '9' and a subfield
'a', and subfield 'a' has an 'authtypecode' set, a 'marc_value' is set, which
seems to always force the display of the field (and subfield), even though none
of the 'visibility' checkboxes (and esp not "Editor") are set.

The special case seems to ignore 'visibility' / 'hidden' completely.

I don't know enough about Koha/MARC internals to assess if this is intended
behavior, but I would find it more sane if the condition would be changed to
actually use the value of the Editor-checkbox.

The only other way I found to actually disable / hide field 600 was to remove
the authtypecode from 600.a, which seems a bit harsh.

After reading more code in addbiblio.pl I see that this special case is
implemented in several places. So I assume / fear this is intended behavior,
and the correct "solution" is to in face remove the authtypecode?

Greetings,
Thomas Klausner
