  • RDA carrier characteristic terms in MARC Bibliographic format
         - Field 300 (Physical Description)
         - Field 340 (Physical Medium) (new subfields)

Attributes of Names and Resources
Attributes of names and titles are typically information that has been recorded in name headings (e.g., date of birth) or in uniform title headings (e.g., key for music) -- or they may have been included in a note in an Authority record for the name or title. With RDA they may be recorded separately from the heading or as part of the heading (or both). New fields for these attributes have been established for names and for resources (works and expressions).
New MARC Authority fields for name attributes:
046 - Special Coded Dates (R)
368 - Other Attributes of Person or Corporate Body (R)
370 - Associated Place (R)
371 - Address (R)
372 - Field of Activity (R)
373 - Associated Group (R)
374 - Occupation (R)
375 - Gender (R)
376 - Family Information (R)
378 - Fuller Form of Personal Name (NR)
New MARC Authority and Bibliographic fields for work and expression attributes:
046 - Special Coded Dates (new subfields only)
336 - Content Type (R)
377 - Associated Language (R)
380 - Form of Work (R)
381 - Other Distinguishing Characteristics of Work or Expression (R)
382 - Medium of Performance (R)
383 - Numeric Designation of Musical Work (R)
384 - Key (NR)
Relationships
Name to resource
  • RDA Appendix I lists possible relationships between a resource and persons, families and corporate bodies, e.g., author, artist, cartographer.
  • MARC already records these types of relationships using relator terms ($e) or codes ($4) in 1XX, 6XX, 7XX, and 8XX in MARC Bibliographic and 1XX, 4XX, and 5XX in MARC Authority.
  • MARC Relator Code list is being augmented with RDA relationships that are not already in the list.
Resource to resource
  • RDA Appendix J lists over 400 relationships that may exist between works, expressions, manifestations and items, e.g., dramatized as (work), indexed in (work), sequel, digest of (expression), filmed with (manifestation), reproduction of (item).
  • RDA identifies several methods for specifying these relationships:
    • identifiers - e.g., many $o, $u, $x, $w, and $0 subfields, and field 856
    • notes - 5XX Bibliographic and 6XX Authority
    • structured descriptions - 76X-78X Bibliographic
    • structured access points - 700-75X Bibliographic and 4XX and 5XX Authority
  • MARC addition: $i defined for the relationship term in Bibliographic 700-75X and 76X-78X and in Authority 4XX and 5XX.
Name to name
  • RDA Appendix K lists possible relationships between persons, families and corporate bodies, e.g., employee, sponsor, descendent family, employer, predecessor.
  • MARC subfield $i added to 4XX and 5XX Authority is also used to specify these types of relationships.
Miscellaneous other changes to MARC for RDA

  • Additional subfield for qualifying informaton in 028 (Publisher Number)
  • ISSN subfield made repeatable in field 490 (Series Statement)

  • Field 040 $e made repeatable and code "rda" added to the MARC code list for Descriptive Conventions to indicate the use of the RDA rules for description. Leader/18 will be coded i with RDA.
  • New Bibliographic format field: 264 - Production, Publicaton, Distribution, Manufacture, and Copyright Notice (R)
  • Experimentation with a technique for including URIs for values (no MARC content designation change) (See Discussion Paper 2010-DP02 for general description.)
