This is a question for Horizon libraries who use Backstage authorities processing. We have problems when series headings that were title-only headings (130 in the authority records) are replaced by series headings that include author and title (100 in the authority records). Most of our bib records with this problem have title-only series headings in 440 fields. When we get the updated authority records from Backstage, the a subfield of the new heading (the author's name) replaces the a subfield in the 440 field (series title) of the bib record. We end up with series headings in bib records with just the author's name and no series title. Does anyone reading this know if there is a way to have Horizon change the series field in the bib record from 440 to 800 if an authority record with a 100 field replaces an authority record with a 130 field? Thanks!
