Step 3.10: Local Bib Subject Matching

A3-10.png

MARS 2.0 matches specified local subject fields against designated national subject authority headings. Many libraries create local subject fields in the 6XX field range with a 2nd indicator of 4, or in local 69X tags.

MARS 2.0 can attempt to match the designated subject heading against a representative national heading. If it does not find a match it will then attempt to find matches in other tags represented in the subject authority file.

Search 6xx x4 against LC

In this option, MARS 2.0 matches the Local subject headings against LC Authority File as if the headings had a 2nd indicator of 0 instead of 4.

For those headings that match a heading in the LC Authority File, the 2nd indicator is changed from 4 to 0. Headings that match a cross-reference in LC are flipped to the established LC form of the heading and the 2nd indicator is again changed from 4 to 0:

 
 original local bib heading:
 650  4 $a American Civil War, 1861-1865.
 
 updated local bib headings:
 650  0 $a United States $x History $x Civil War, 1861-1865.
 

After the matching is completed, all remaining Local subject headings (i.e., those that did not match a heading in LC) are removed from the records.
