Appendix A. MARC 21 Descriptive Conventions Code

 

 

A1. Introduction

 

In MARC 21 bibliographic records, a code may be used in field 040, subfield ‡e, to indicate when specific cataloging conventions have been followed in addition to the conventions identified in the descriptive cataloging form (Leader/18). This appendix offers guidance in using “dcrmms,” [dcrmmss?] the code designating DCRM(MSS), in 040 subfield ‡e.

 

 

A2. Full-level DCRM(MSS)

 

Apply the code “dcrmms” to records for resources cataloged at full level (i.e., the normative application of these rules). The fact that such records follow the full-level provisions of DCRM(MSS) is indicated by the blank value assigned in the encoding level (Leader/17) and the code “dcrmms” in 040 subfield ‡e.

 

 

A3. Collection-level DCRM(MSS)

 

Do not apply the code “dcrmms” to records for resources cataloged according to the collection-level guidelines found in Appendix B. The fact that such records contain collection-level descriptions is indicated by the value c assigned in the bibliographic level (Leader/07). The guidelines in Appendix B suggest factors to consider in constructing collection-level records for rare materials and provide examples useful in a special collections context. However, the conventions conform substantially to those governing standard collection-level descriptions, as presented in Cataloging Service Bulletin, no. 78 (Fall 1997).

 

 

A4. Core-level DCRM(MSS)

 

Apply the code “dcrmms” to records for resources cataloged according to the core-level guidelines found in Appendix C. The fact that such records follow the core-level provisions of DCRM(MSS) is indicated by the value 4 assigned in the encoding level (Leader/17) and the code “dcrmms” in 040 subfield ‡e.

 

 

A5. Minimal-level DCRM(MSS)

 

Apply the code “dcrmms” to records for resources cataloged according to the minimal-level guidelines found in Appendix D. The fact that such records follow the minimal-level provisions of DCRM(MSS) is indicated by the value 7 assigned in the encoding level (Leader/17) and the code “dcrmms” in 040 subfield ‡e.

 

 

A6. Microforms and digital reproductions of books

 

Apply the code “dcrmms” to records for microforms and digital reproductions of books if the descriptive portion of the record conforms to DCRM(MSS) (full, core, or minimal level). If, however, DCRM(MSS) (full, core, or minimal level) is not used in all aspects (e.g., if the size of the manuscript is not recorded in the physical description area), do not use the code “dcrmms.”

 

 

A7. Nonbook formats

 

Do not apply the code “dcrmms” to records for non-manuscript materials such as serials, maps, music, and graphics, even though they may have been cataloged according to an adapted, “DCRM(MSS)-like” standard.[1] Do, however, apply the code "dcrmms" to individual and special issues of serials cataloged separately as manuscripts according to the provisions of Appendix H.

 

 

 

A8. “Special collections cataloging”

 

In this context “special collections cataloging” means fuller use of notes, access points, and other elements that are not specifically called for in AACR2 or its predecessors, but that follow the spirit of DCRM(MSS) without following its rules completely. Such cataloging is frequently done for 19th-century and later materials housed in special collections. Do not apply the code “dcrmms” to records for “special collections cataloging” unless the cataloging follows the descriptive requirements of DCRM(MSS) completely (full, core, or minimal level).

 

 

A9. Earlier codes

 

If an existing record contains an earlier code in 040 subfield ‡e, such as “appm” (Descriptive Cataloging of Archives, Personal Papers, and Manuscripts), and the description is being updated to DCRM(MSS) standards, delete the earlier code and add the “dcrmms” code to the end of the 040 field in subfield ‡e.
