>Subject: [PATCH] Bug 24094: Strip trailing spaces and punctuation from
> authority headings
>
>Both when searching for and creating new authorities we need to remove
>punctuation that exists in the bibliographic record but does not belong in
>the authority record.
>
>For example, a series with a volume contains a semicolon in the bib record,
>however, this should not be passed to the authority as the volume is not
>included in the authority record.
>
>To test:
> 1 - Set AutoCreateAuthorities to 'generate'
> 2 - Set BiblioAddsAuthorities to 'true'
> 3 - Set CatalogModuleRelink to 'Do'
> 4 - Find or create a record with:
>    a 100 field with a subfield e preceded by a comma: 100 $aBoring, M. Eugene M ,$e author
>    an 830 field with a volume preceded by a semicolon: 650$aLord of the rings ;$v 3.
> 5 - Save the records and check the links
> 6 - Note punctuation is passed through
> 7 - Save again, auth records are created again
> 8 - Apply patch
> 9 - Save again, new auth records are created again
>10 - Check the records, punctuation has been removed
>11 - Save again, no more records created.
