[Evergreen-catalogers] Authorities question

[Mike Rylander]

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,
