Deleted; heading split into two or more headings:
Code s (Leader/05) indicates that the record has been deleted from a file because the heading has been split into two or more headings, requiring a new authority record for each. The heading from the deleted record is included in each of the new authority records as a tracing in a 4XX See From Tracing field.
An automated authority control system can scan other authority records until it locates two records which contain the deleted heading used as a 4XX See From Tracing. At that time, the system can display the deleted heading and the two replacement headings for review or take other automatic actions.
(When a heading is split, a computer cannot automatically replace the old heading in bibliographic records. Manual intervention is required to determine which of the new headings is appropriate in each bibliographic record containing the old heading.)
