Nel ten Brug: I looked at the Library of Congress' web page on the MARC format and found the following: http://www.loc.gov/marc/bibliographic/bd852.html 852 $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 $p (Piece designation). Designation may be an identification number such as a bar code number or an accession number. 852 81$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. -- Mitch Turitz On Apr 21, 2009, at 4:06 AM, Nel ten Brug wrote: > Dear all, > > The Rijksmuseum Research Library, the largest museum library in the > Netherlands, is currently trying to map its data to MARC 21.
