>Subject: [PATCH] Bug 33159: Correctly form thesaurus term for non-subject
> headings
>
>Bug 30280 fixed things for subject heading, but didn't take into account
>that all non-subject headings are considered LCSH - this means we can't
>really handle different thesauri for controlled headings outside of
>subjects - maybe a topic for a new bug, but we should fix matching for
>them now
>
>To test:
> 1 - Set sysprefs:
>    RequireChoosingExistingAuthority - don't require
>    AutoCreateAuthorities - generate
>    CatalogModuleRelink - Do
>    AutoLinkBiblio - Do
>    LinkerModule - first match
> 2 - Find a record with an author attached to an authority, I used
>  biblionumber 3 "Introduction to Attic Greek"
> 3 - Edit in advanced editor
> 4 - Delete the $9 link
> 5 - Save the record
> 6 - It generates a new number
> 7 - Repeat 4-5, it does it again
> 8 - Apply patch and restart all
> 9 - Repeat 4-5
>10 - It links to the original authority
