[Koha-devel] Marc Extract and subject headings

[Ian Bays]

Hi.  These are potentially two quite different requirements although 
solutions may be closely related.  David is asking about the Koha-generated 
$9 subfields (RLIN) against authorised values for subjects, authors etc 
coming out.  I see in the Tools> MARC Export screen you can elect to "Don't 
export fields" which you could enter (say) "1009 1109 6509 6909" following 
the example on screen this should exclude subfield 9 of 100, 110, 650 and 
690 tags.  I have not tried it but it looks as if it should do what you are 
asking...

As for the discussion on the 9xx tags on import I would think a similar 
options field on import that allows to exclude fields or subfields would be 
useful to many.  It might also be good if the values entered were persistent 
in some way so you don't need to remember them and re-enter every time.

Hope that helps.
Ian
