[Evergreen-catalogers] Authorities question

[Mary Llewellyn]

Thanks for your responses, Mike and Elaine.  Since we're still sitting on the edge of the authority pool with our toes barely wet, as it were, I wasn't certain what was an issue and what wasn't.  The experience and clarification helps. 

Mary

Mary and Elaine,

To clarify what happens internally in Evergreen when you delete an authority, the bibs do indeed retain the $0 but the internal linking is removed.  Causing a reingest of all previously-linked bibs by altering the MARC would cause the deletion to fail for any non-trivial number of linked bibs.  Just as incoming (migrated, imported) bib data may have spurious $0 fields, those dangling fields are of no consequence once the authority id deleted.

Hope that helps,
