Most fields are working, I only get an error if I want to search the author field. It is Error 114.
the MARC output of the GVK looks as follows:

(I based the filter on the BIBSYS filter.)
More information regarding the Z39.50 interface to the GVK can be found here: http://www.gbv.de/du/z3950/z3950-info.shtml
and here: http://www.bidmon.de/RefMan_Z3950.htm#GBV
(both pages are in German, but it should be easy for you to figure out the content)
If we get this working well, I would definitely recommend putting it into the app package - this is perhaps the biggest available catalogue in Germany.
