Any idea why my Koha install would not show the $b field in the title under the Normal view the way yours and Rachel's does?  I noticed she is on a later release than I am.

I've tracked down the commit that enables the display of the subtitle and it looks like it's old enough that you should have it. It was in the 3.0 stable release: kohabug 1621 - add subtitle to main results and details pages Including the subtitle in search results and OPAC and staff details templates. The subtitle is expected to be in the MARC subfield that is mapped to the (now nonexistant) column bibliosubtitle.subtitle.

What about the "Koha Link" field under the Advanced Constraints for a subfield.  My reading of this is that this is the link between the Koha DB fields and the MARC fields

It sounds from those notes above that the fix depends on the "Koha Link" value for 245$b to be set to "bibliosubtitle.subtitle," a Koha field that, as the notes say, doesn't exist anymore. The trouble is, since it doesn't exist you can't choose it from the interface. Perhaps the only option is to change it in MySQL? "UPDATE marc_subfield_structure SET kohafield = 'bibliosubtitle.subtitle' WHERE tagfield = 245 AND tagsubfield = 'b'" ...and add "AND frameworkcode = 'XXX'" if you only want to change the XXX framework. Maybe Galen could chime in with comments since he was the author of the patch. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
