Could we please not make the mistake of thinking every field is worth the
same? Of the fields below (see my report below), some do not appear at all
within the WorldCat aggregation, whereas others appear a significant amount
and a bunch are somewhere in between. If a tag only appears 33 times out of
nearly 300 million MARC records, it likely isn't as important as one that
appears over 50 million times. Just sayin'.
