Hi, I'm looking for a way to trace deleted authorities. A table for biblio is deletedbiblioitems, but I found no deletedauth_header or something similar for auth records. I only need the auth_id. Any idea? Thanks. Stefano

A solution could be to look at the zebraqueue, that logs these events: authorityserver recordDelete authorityserver specialUpdate biblioserver recordDelete biblioserver specialUpdate specialUpdate means new or updated record. Bye. Stefano
