Thanks, that helps a lot. I think I understand now. Good link there. I was getting confused at step 2. I understood everything else pretty well though.
I'd like to do something similar with call numbers. That is to only show the unique call numbers. Now I'm seeing how to do it, I wasn't so sure how it worked before. Just have to figure out the syntax needed to make a key of the 952$o now, and that shouldn't be to hard. I should be able to find a good example of that in the xsl. On the other hand maybe not, since the xslt processing isn't done on the staff interface. I don't think my librarians would be satisfied with the 245$b only showing up on the opac interface.
