RDA 2.15.1.7 (Identifier for the manifestation--Basic instructions--Qualification) says, "If the resource bears more than one identifier of the same type, record a brief qualification after the identifier." And provides the following examples:
ISBN 0-435-91660-2 (cased) ISBN 0-435-91661-0 (pbk.) ISBN 0-387-08266-2 (U.S.) ISBN 3-540-08266-2 (Germany) ISBN 0-684-14258-9 (bound) ISBN 0-684-14257-0 (pbk.) So I think you are ok to continue to record "(pbk.)" etc. --Ben Benjamin Abrahamse Cataloging Coordinator Acquisitions, Metadata and Enterprise Systems MIT Libraries 617-253-7137 -----Original Message----- From: Resource Description and Access / Resource Description and Access [mailto:RDA-L@listserv.lac-bac.gc.ca] On Behalf Of Henry Lam Sent: Friday, November 16, 2012 1:45 AM To: RDA-L@listserv.lac-bac.gc.ca Subject: [RDA-L] Hardback & paperback, and their ISBN Hi all I hope someone can share your insight on this. Are hardback and paperback of the same imprint treated as same manifestation in RDA? When we record the ISBNs in MARC in RDA, should we include the qualifier in bracket (ie hb/pbk, or hardback/paperback)? Regards Henry
