This field is used to identify hierarchically linked material at the highest level. The resource to which the link is made is at the highest level, and the record containing this field is at the intermediate level or item level.
| FIELD/SUBFIELD | REPEATABILITY | ||

| 1 | Linking data | nr | |
Subfield 1 is used to enter the identification number of the record at the higher level, i.e., the record for the whole collection.
Field 461 is used in the cataloguing of legacy collections and artificial collections if the material is catalogued at multiple levels. It is used in records at the lower and intermediate level.
A link from an item or subset to a set is always an upward link.
