Ref: Koha 3.14.05 on Ubuntu OS 12.04 LTS Packages into VirtualBox Hi, By making changes in the 280 heading field to create an UDC authority type, the filling process of the bibliographic field 675, subfield <<a>>, is automatic, as can be seen in the images attached. But, unlike the other types of authority, the data of the subfield <<3>>, i.e., the corresponding authority record number is missed. Without this identifier, nobody can retrieve bibliographic records by searching UDC authority headers, although the UDC notations can be seen in ISBD format, not in normal view. I presume there is a script somewhere linking fields 280-608 that can be changed to correct this fault. Can anyone confirm if my assumption is this true and, if so, give me detailed instructions, i.e., step by step please (I'm just a librarian) on how to fix this? And finally, how to change to TEXT the data type of the subfield <<c>> of the field 280, since some UDC notations have huge callouts? Many thanks in advance!
