| Campo | 1st indicator | 2nd indicator | Note |

| 240 | Field 240 cannot be controlled | ||
| 400 | While series headings are access points, the primary function of the 4XX fields is to reflect the transcription of series statement on an item, and secondarily to provide access as a series added entry. Currently, if 440 fields were controlled, the 'correct' 440 heading text could be incorrectly changed to the new heading in the authority record. This would result in the loss of the field's primary function of transcribing the series statement as found on the item. Only series headings coded 8XX can be controlled. |
