Deleted:
Code d (Leader/05) indicates that the record has been deleted. This code is used for those situations when neither code s nor code x is appropriate, or when an organization chooses not to use code s or x. Some level of manual intervention may be needed to effect the change in bibliographic records because the deleted heading may or may not be carried as a 4XX See From Tracing field in other authority records and a 682 field explaining the delete may be present in the record marked for deletion.
Examples:
Leader/05 d
150 ##$aFruit processing
682 ##$iThis heading has been replaced by the heading$aFruit--Processing,$ia heading not distributed because it uses a freefloating subdivision controlled by a pattern heading.
