Correct Coding of ISBN in MARC21 field 020 in RDA & AACR2 Cataloging with Examples

-


Several years ago the definition of $z of the 020 (International Standard Book Identifier) was expanded—it is now used for “structurally invalid” ISBNs (those that are too short, too long, wrong check digit, etc.) and also for “application invalid” ISBNs (ISBNs for a manifestation that would be described in a different bibliographic record).

The LC-PCC Policy Statement for 2.15.1.7 provides the following instruction:  
Record ISBNs in $z (Canceled/invalid) of MARC field 020 if they clearly represent a different manifestation from the resource being cataloged and would require a separate record (e.g., an ISBN for the large print version, e-book, or teacher’s manual on the record for a regular trade publication). If separate records would not be made (e.g., most cases where ISBNs are given for both the hardback and paperback simultaneously), or in cases of doubt, record the ISBNs in $a (International Standard Book Number) of MARC field 020

Please remember to use $z for ISBNs when appropriate. For regular print publications, this is most likely to occur when you also have an ISBN for a large print edition or e-book that would be cataloged on a separate record.

When we do not use the correct subfield code in field 020, systems that receive records from LC may incorrectly merge or replace records for the wrong format—we have received several complaints about this, and we hope we can improve the situation with your help.

RESOURCE DESCRIPTION & ACCESS RDA


Question: Record ISBNs in 020 $z if they represent a different manifestation from the resource being cataloged.

  • If a printed monograph presents different ISBNs for different manifestation, do we have to transcribe them like below given example?


AACR2            020 $a 9780415692847 (hardback: alk. paper)
                                        020 $a 9780203116852 (e-book)

RDA                020 $a 9780415692847 (hardback: alk. paper)
                                      020 $z 9780203116852 (e-book)   (recorded in $z ISBN clearly representing an e-book version of the same manifestation)

Answer: Yes, the example you have given shows LC’s practice documented in LC PCC PS 2.15.1.7 for multiple ISBN:

“…if they clearly represent a different manifestation from the resource being cataloged and would require a separate record (e.g., an ISBN for the large print version, e-book, or teacher’s manual on the record for a regular trade publication). If separate records would not be made (e.g., most cases where ISBNs are given for both the hardback and paperback simultaneously), or in cases of doubt, record the ISBNs in $a”

While not part of the question and answer it would be nice to show subfield q being used. 


RDA                020 $a 9780415692847 $q (hardback: alk. paper)

                                      020 $z 9780203116852 $q (e-book)

RDA -- INTRODUCTION BACKGROUND AND HISTORY

-
Resource Description and Access ( RDA ) is a standard for cataloguing that provides instructions and guidelines on formulating data for resource description and discovery. Intended for use by libraries and other cultural organizations such as museums and archives, RDA is the successor to the Anglo-American Cataloguing Rules, Second Edition (AACR2), the current cataloging standard set for English language libraries. RDA was initially released in June 2010. In March 2012, the Library of Congress announced it will have fully implemented RDA cataloging by March 31, 2013. Several other national libraries including the British Library, Library and Archives Canada, National Library of Australia, and Deutsche Nationalbibliothek also planned to implement RDA in 2013. Background RDA emerged from the International Conference on the Principles & Future Development of AACR held in Toronto in 1997. It was quickly realised that substantial revision of AACR2 was required, which
