Nel ten Brug:

I looked at the Library of Congress' web page on the MARC format and found the following:

$p - Piece designation
Identification of a single piece when the holdings information does not contain an 863-865 (Enumeration and Chronology) or 876-878 (Item Information) field that contains a subfield $p (Piece designation).
Designation may be an identification number such as a bar code number or an accession number.
85281$a [location identifier] $b0131$p1100064014
Piece designation number may be preceded by an uppercase B or U to specify whether the piece is bound or unbound. When no piece designation exists, a double slash (//) may be recorded in subfield $p to signify that the field relates to a piece.

Dear all,

The Rijksmuseum Research Library, the largest museum library in the
Netherlands, is currently trying to map its data to MARC 21. We have only
limited MARC experience, and we have a particular problem: our library
collection is also a part of the museum collection. This means we have to
give every item its own ‘inventory number’. Are there libraries who have
this same obligation, and where in MARC do they place this number? Since
we are using KOHA, we have been using the KOHA item field tag 952$t (copy
number, in MARC this would be 852$t), but I understand this is used for
items with the same call number. Can someone please help?
