Description Nick Clemens (kidclamp) 2023-03-21 19:39:07 UTC
See notes for character 11 here:
https://www.loc.gov/marc/authority/ad008.html

n - Not applicable
1XX heading is not a name, name/title, or uniform title formulated according to descriptive cataloging rules and is not appropriate for use as a main or added entry in bibliographic records. 

We need a negative search, or another way to exclude this from matching, they are valid for 1XX, but not 6XX
Comment 1 Heather Hernandez 2025-01-10 16:50:49 UTC
I'm seeing the text of character position 11 value "n" as a little different:

"n - Not applicable
1XX heading does not conform to subject heading system/thesaurus conventions and is not appropriate for use as a subject added entry in bibliographic records."

But your need is still valid:  the value in a 151 in a record like this needs to be excluded from matching any 651 in a bibliographic record--but it would still be valid matching its 151 field with the heading used as a 110.
