    Logic order

    1. The authority 1XX must be eligible to be linked to bib field 6XX.
      1. If it is not, then do not link regardless of authority record’s 008/11
    2. If the authority 1XX is eligible to link to bib field 6XX then check bib field indicator 2 value is a matched to authority record’s 008/11
      1. If not, then do not link authority record.
    3. Assuming the first two are satisfied. When the bib field indicator 2 = 7 then check that the bib subfield $2 matches the authority record 040$f.
      1. If not, then do not link authority record.
    4. TBD requirement: Handling bib field indicator 2 = 4

    If 6XX has Bib Indicator 2 = 7 then check bib subfield $2 for the codes listed below AND only link authority records that contain the same code in the authority record 040 $f (Cataloging Source / Subject heading / thesaurus conventions) OR we can use the same logic as what we use to determine authority source file value
