Wayne,
We globally change our MeSH headings in Ser Sol bib records to 690 (a field
we protect) just before overlay with a new Ser Sol load. (Same problem,
can't protect them at the indicator level.) Then after the load, we change
them all back. Not perfect, but not too difficult. I don't know if Voyager
has the same global update capability as III, though.
