DCM Z1: 035 System Control Number
As part of the conversion from LC's previous system (MUMS) to the current LC Database, an 035 field was added to every name/series authority record. An 035 is also added to all new and updated authority records coming into the LC Database from the overseas offices or the NACO nodes as part of the load process.
The DLC 035 is deleted programmatically by LC's Cataloging Distribution Service (CDS) when the record is distributed.
Do not add, change, or delete 035 fields. Catalogers have no responsibility for the 035 field.
