If a MARC bib is modified by this batch job, do not duplicate the item tags embedded in it (e.g., 952 for MARC21). When modifying a bib record, any embedded item tags must be removed before calling ModBiblio - perhaps this should be moved to ModBiblio itself. Also removed an error in the job's help text.
