A link to this thread was forwarded to me at the library.
The VWML only started to convert its old card and in-house catalogues into MARC records a few years ago. We've converted a large number of records, but it's still not everything. You can find our catalogue here: http://catalogue.efdss.org/
Sharing our records with larger union catalogues is something that we would like to do eventually - but we're taking it one step at a time.
