This field contains detailed information on the location of the holdings. In contrast to field 850, field 851 allows the recording of the full name and address of the holding institution and specific data about the exact location of the item.
The custodian and the owner of a work are usually the same and are recorded in field 851 for these kinds of items:
When an item is not at the owner's address, the name of the current custodian is recorded in subfield ǂa and the owner's name and address are recorded in field 561. If a work was originally commissioned/installed at one site but was subsequently moved to another location, the name of the present site is recorded in subfield ǂb and the name of the original site is recorded in field 561.
Field 851 is now obsolete in MARC 21 but remains valid for use in WorldCat. It is currently used in records created for the National Union Catalog of Manuscript Collections (NUCMC). Field 851 is retained in the WorldCat record.
