Step 6.12: Older Forms of Headings
MARS 2.0 can update authorities where the older form of the heading is no longer included as a See xref (4XX). As national authority files are updated, it becomes increasingly likely that older unmatched bib headings will now find a matching authority against which to update.
However, when the older form of the heading does not meet the criteria necessary in order to be added back into the record, it can become difficult to manually link up these headings with the current authorized form:
LC name authority n 50000918 updated with death date: 100 1 $a Parker, Fan, $d 1908-2004 400 1 $a Pockrose, Fania M., $d 1908-2004 older form of heading: 100 1 $a Parker, Fan, $d 1908- n 50000918 updated with older form of heading: 100 1 $a Parker, Fan, $d 1908-2004 400 1 $a Pockrose, Fania M., $d 1908-2004 400 1 $w nnea $a Parker, Fan, $d 1908- $5 UtOrBLW
Hide 4xx from patrons
MARS 2.0 can add $w nnea to the older forms of the headings in order to hide those specific See xrefs (4XX) from displaying to library patrons within the OPAC.
Exclude generic names
Generic names on older headings may potentially lead to false matches, depending on the integrity of the cataloged database. MARS 2.0 can exclude generic names from being included in the older forms of the headings so as to reduce updating headings that should not be considered.
