What is the difference between the 0350 and the 035A indexes?
There are two indexes in Voyager relating to the 035 subfield a: the 0350 index and the 035A index
The 0350 search index appears in the list of available heading searches in all staff modules (provided it is not Staff Suppressed)
and is distributed as:
0350 System number for deduping (035a).
The same index appears in the list of indexes the user may choose from when determining the replace/merge rules in the Bib Dup Detection profiles they set up in System Administration.
Using the 0350 index makes for a more stringent (therefore more accurate) deduping process.
The 035A index ignores the text; just looks at the number. This causes incorrect overlaying if you have more than one type of record
in the database with the same number.
The 0350 index does not ignore the text that comes before the number. In other words, it looks at the whole subfield a.
For example -
Existing Record in the system: 035 $a (OCoLC) 123456789
Imported Record: 035 $a (CStRLIN) 123456789
If you are matching based on the 035A, the existing record will be overlayed by the new record
because the numbers are the same.If you are matching based on the 0350, the existing record will be not be overlayed by the
new record; the record will be added.
Make sure that your SysAdmin > Cat > Bib Dup Detection Profiles have the "System number
for deduping (0350)" as the selected index rather than the 035A index or add it in addition to the 035A
