That is the appropriate place. As you probably know, we are not controlling the list of type values for identifier, although we may in the future establish a controlled vocabulary for it. It makes sense to fix the stylesheet unless people using MODS object to retaining the OCLC number in a converted record. Rebecca Rebecca S.

It seems that the OCLC number could go into a <identifier type='oclc'>. Does anyone see a glaring problem with that idea? Is there a better place that I'm overlooking? Would there be any interest in a patch to MARC21slim2MODS3-4.xsl for this operation? -Tod Tod Olson <[log in to unmask]> Systems Librarian University of Chicago Library
