[Koha] how to make 050 LCC call number used

I am trying to make 050 Library of Congress Call number to be used.

From "parameters" >> "Biblio framework" " >> "MARC structure", I know 050 is there. However, if I select "display only used tags/subfields". 082 Dewey Decimal Call number shows. Is there anyway to disable 082, but enable 050 LCC call number?

or I have to change the PERL source code? Thanks, YH _______________________________________________ Koha mailing list Koha@lists.katipo.co.nz http://lists.katipo.co.nz/mailman/listinfo/koha
