Hi folks, We have a question for someone with MARCEdit expertise. If the following field is present: *=650 \7 $aOur local subject heading* we want to add to the end of the line: *$2local* The problem is, sometimes our local subject heading also has other subfields like $x or $z, and we want to add subfield $2 at the end of the line, so we can't just use find and replace (or can we with a regex maybe?). We think we're supposed to be using the edit subfield tool, but we don't want to add our subfield to every 650, just the ones containing our local subject heading. Can someone point us in the right direction?
