Hi Nathan, The demo at http://kubrick.no-ip.info/opac/opac.php is searching against an III target, using the 'opac' record syntax to pull back item-level holdings info. I'd be happy to share the code -- in fact, I plan to package it up when I get a chance and post it on my site. The only outstanding problem is handling diacritics properly but it works otherwise.
