One of the name authority cleanup projects will add 043 and 781 fields to geographic name authority records, continuing a project begun in 2006 to enhance name authority records with geographic data. Another name authority cleanup project removes unnecessary ending punctuation from 1XX headings in older authority records (generally those created before a policy change in 1989 to exclude such punctuation). These records have challenged local systems and authority control vendors for many years.

The creation of subject authority records for validation purposes has resulted in the distribution of 5,300 validation records to date. Beginning February 26, 5,000 validation records will be distributed weekly in addition to the approximately 200 new and changed subject authority records normally processed through the weekly editorial process. This number may increase to 25,000 validation records per week in the future. The total number of new validation records is currently estimated to be between several hundred thousand to over a million.
