RDA in MARC

MARC 21 Updates 9, 10, and 11 include all changes to MARC for use with RDA approved through 2010. The list below has been updated to include changes under consideration in June 2011. Those not-yet-approved changes are indicated below as "proposed" or "under discussion", and are linked to their relevant MARBI Proposals and Discussion Papers.

Content, Media and Carrier Types and Characteristics

RDA Content Types
MARC already indicates content type in LDR/06.
RDA contains a list of English language content types for which a new field 336 was provided in MARC Bibliographic and in MARC Authority.
Field 336 may contain the RDA term ($a) or a code ($b); codes were established in MARC Update 10.
For a table that relates the MARC LDR/06 to the corresponding RDA content terms and MARC codes for RDA content terms see: Term and Code List for RDA Content Types.

RDA Media Types
MARC already indicates media type in field 007/00.
RDA contains a list of English language media types for which a new field 337 is provided in MARC Bibliographic and in MARC Holdings.
Field 337 may contain the RDA term ($a) or a code ($b); codes were established in MARC Update 10.
For a table that relates the MARC 007/00 to the corresponding RDA media terms and MARC codes for RDA media terms see: Term and Code List for RDA Media Types.

RDA Carrier Types
MARC already indicates carrier type in field 007/01.
RDA contains a list of English language carrier types for which a new field 338 is provided in MARC Bibliographic and in MARC Holdings.
Field 338 may contain the RDA term ($a) or a code ($b); codes were established in MARC Update 10.
For a table that relates the MARC 007/01 to the corresponding RDA carrier terms and MARC codes for RDA carrier terms see: Term and Code List for RDA Carrier Types

RDA Carrier Characterisitcs - proposed
MARC provides for recording carrier characteristics in Bibliographic fields 300, 340, and 5XX and in Bibliographic and Holdings field 007 (coded form).
RDA contains lists of English language terms that can be used to express carrier characteristics and also allows expression via notes.
RDA carrier characteristic notes – MARC Bibliographic fields 500 (new subfield $i (Display text) proposed)and other 5XX
RDA carrier characteristic terms in MARC Bibliographic format
Field 300 (Physical Description) (subfield $b repeatable, otherwise no change)
Field 340 (Physical Medium) (new subfields proposed)

New Bibliographic format fields proposed
344 – Sound Characteristics (R)
345 – Projection Characteristics of Motion Picture Film (R)
346 – Video Characteristics (R)
347 – Digital File Characteristics (R)

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 Corporate Body Attributes (R) (NEW) (proposed) – use to indicate the jurisdiction types for names of places
370 - Associated Place (R)
371 - Address (R)
372 - Field of Activity (R)
373 - Affiliation (R) - extend the field to contain names of associated institutions for corporate bodies and rename field Associated Institution (proposed)
374 - Occupation (R)
375 - Gender (R)
376 - Family Information (R)
377 - Associated Language (R)
378 - Fuller Form of Name (R) (NEW) (proposed)

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 (proposed) - extend to include the language of an expression and add to MARC Bibliographic.
380 - Form of Work (R)
381 - Other Distinguishing Characteristics of Work or Expression (R)
382 - Medium of Performance (R) - additional subfields (under discussion)
383 - Numeric Designation of a Musical Work (R) - sdditional subfields (proposed)
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 will be augmented with RDA relationships that are not already in the list when the RDA list is final and available.

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 - 7XX Bibliographic and 4XX and 5XX Authority
MARC addition: $i defined for the relationship term in Bibliographic 7XX 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 specificity in field 502 (Dissertation Note)
ISSN subfield made repeatable in field 490 (Series Statement)
Additional codes in various 007 and 008 character positions
Additional subfields in 033 (Date/Time and Place of an Event) and 518 (Date/Time and Place of an Event Note)
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.
Experimentation with a technique for including URIs for values (no MARC content designation change) (See Discussion Paper 2010-DP02 for general description.)
Additional fields or subfields proposed for RDA publication, production, distribution, and manufacture locations, agencies, and dates
Additional field or subfield proposed for copyright date that appears on the item
