Thanks for the clarification - I assume you mean not only in batch
mode, but even one at a time

So it seems I need to export my biblios merge/overlay the new data
with an external MARC editor and then re-import. The silver lining is
the certainty of having reliable matching data (most of my biblios
have neither ISBN nor ISSN).

So the question remains as to editor suggestions, especially if one is
available that does handle batch updates; although if one is
particularly good at one-at-a-time merging that's valuable information
as well.

I'm assuming bringing in whole new fields and adding new
multiple-entry ones shouldn't be a problem, but I'd like to be able to
specify the fields-in-common, as to which are OK to over-write vs
which shouldn't be touched.
