Hi Nathan,

I apologize for the late reply.

You're right, it does appear to be a namespace issue. The z39.50 searching 
goes through a somewhat complicated process of being converted from MODS to 
MARC to XML, so there are certainly plenty of points where the XSLT can get 

What are the options you're using for the ADS z39.50 target so I can do some 
testing myself? (database name, character set, etc.?)

In the meantime, though it's not as flexible, you could take a shot using a 
script I wrote a while back, if you were interested.
