Dear DCRM-L colleagues,

Following up on discussion at Midwinter and questions from rare materials catalogers about DCRM/RDA issues, the DCRM(B) for RDA Revision Group, and Controlled Vocabularies Subcommittee, with the assistance of BSC web team liaison Randy Brandt, have updated the BSC page offering information on DCRM and RDA, accessible through the link below:


For your convenience, I’ve also copied the entire page to the end of this message.

The revised page provides guidance on various RDA issues, including:

·         how to properly employ DCRM(B) with AACR2 or RDA

·         how to employ DCRM(S), until the completion of the RDA CONSER standard record (CSR)

·         the use of relationship designators (in RDA)

The page also offers a summary of information about the DCRM(B) for RDA Revision Group.

All questions and comments are welcome.


Bibliographic Standards Committee
BSC statement on DCRM and RDA

Updated April 18, 2013

The Bibliographic Standards Committee is neutral regarding RDA, neither encouraging nor discouraging agencies regarding implementation of RDA-acceptable DCRM records.

Until a full revision of DCRM(B) for RDA is complete, agencies creating DCRM(B) records should follow one of the following options:

  1.  Continue to catalog according to DCRM(B) and AACR2 for descriptive cataloging, using RDA guidelines for access points; or
  2.  Create RDA records by applying the provisions for rare materials included in the RDA BIBCO Standard Record<http://www.loc.gov/aba/pcc/scs/documents/PCC-RDA-BSR.pdf> (BSR). This instruction applies also to agencies not producing BIBCO records.
     *   If used, the BSR for rare materials should be followed consistently throughout the entire description; it is not to be applied only to selected areas or elements.
     *   The MARC record leader should be coded as following ISBD (coded i in LDR/18), with both ‡e rda and ‡e dcrmb (directly after the language of cataloging (‡b)) in the 040 field.

Rare Serials

Catalogers of rare serials should continue to catalog according to DCRM(S) and AACR2 for descriptive cataloging, using RDA guidelines for access points. An RDA CONSER Standard Record (CSR), including instructions for rare serials, is in progress. This instruction will be revised once the CSR is approved. Items thus cataloged should still be coded a in LDR/18 and ‡e dcrms in the 040 field.

Relationship Designators

Relationship designators allow the relationship between a person, family, or corporate body and a resource to be specified in a catalog record. In MARC bibliographic records they are most commonly used in 100, 110, 700, or 710 fields.

Relationship designators contained in RBMS Controlled Vocabularies: Relationship Designators for Use in Rare Book and Special Collections Cataloging<http://www.rbms.info/committees/bibliographic_standards/controlled_vocabularies/index.shtml> may be used in catalog records created according to any standard, including RDA, that permits use of relationship designators from a source external to the standard.

DCRM(B) for RDA Revision Group

In January 2013, at the ALA Midwinter Meeting, the Bibliographic Standards Committee charged the DCRM(B) for RDA Revision Group to move rare materials cataloging forward in terms of RDA. The formation of this group was recommended by the DCRM-RDA Task Force<http://www.rbms.info/committees/bibliographic_standards/dcrm/rda/dcrm-rda.html>, which submitted its final report to BSC in October 2012. The revision group's initial plan is to conduct a rule-by-rule comparison of DCRM(B) and RDA; to be completed by the 2013 ALA Annual Conference. They plan to provide frequent updates on their progress, and encourages participation from the wider rare materials cataloging community.

  *   DCRM(B) for RDA Revision Group Wiki<http://dcrmbrda.pbworks.com/w/page/60950383/FrontPage>


  1.  Undertake a complete revision of DCRM(B) based on RDA, to include changes in terminology, structure, and examples;
  2.  Issue/promulgate the revision as appropriate (including via the RDA Toolkit<http://www.rdatoolkit.org/>);
  3.  Engage in dialogue with the rare materials community throughout the revision process through postings on a dedicated wiki<http://dcrmbrda.pbworks.com/w/page/60950383/FrontPage>, and discussion on DCRM-L, and at Midwinter and Annual meetings;
  4.  Insure consistency of DCRM(B) for RDA with RDA and with rare materials provisions in the BSR for RDA by recommending updates to the BSR and changes to RDA rules as necessary and appropriate;
  5.  Complete a first draft of revised DCRM(B) by Annual 2014.
