RDA in MARC:
MARC 21 Updates 9-18 include all changes to MARC for use with RDA approved through June 2014.
CONTENT, MEDIA, and CARRIER TYPES and CHARACTERISTICS
For examples:
RDA Content Types
RDA contains a list of English language content types for which a new field 336 was provided in MARC Bibliographic and in MARC Authority.
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.
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.
RDA Carrier Characteristics
MARC provides for recording carrier characteristics in textual form in Bibliographic fields 300, 340, and 5XX and in coded form in Bibliographic and Holdings field 007.RDA contains lists of English language terms that can be used to express carrier characteristics and also allows expression via notes.RDA carrier characteristic terms in MARC Bibliographic format
-- Field 300 Physical Description
-- Field 340 Physical Medium (new subfields)
-- New Bibliographic format fields
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:
371 Address (R)
374 Occupation (R)
375 Gender (R)
New MARC Authority and Bibliographic fields for work and expression attributes:
046 Special Coded Dates (new subfields only)
380 Form of 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 Code List for Relators 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
-- structured descriptions - 76X-78X Bibliographic
MARC addition: $i defined for the relationship term - in Bibliographic 700-75X (see specific field) and 76X-78X (subfield $i) and in Authority 4XX and 5XX (subfield $i).
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.Additional subfield specificity in field 502 (Dissertation Note)Additional subfield for qualifying information in 015 (National Bibliography Number), 020 (International Standard Book Number), 024 (Other Standard Identifier), 027 (Standard Technical Report Number), 028 (Publisher or Distributor Number)ISSN subfield made repeatable in field 490 (Series Statement)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 Description Convention Source Codes to indicate the use of the RDA rules for description. Leader/18 will be coded i with RDA.Field 250 made repeatable in order to better accommodate edition statements for music and other resources cataloged according to RDA.New Bibliographic format field: 264 Production, Publication, Distribution, Manufacture, and Copyright Notice (R)Subfield $c (Location of meeting) made repeatable in X10 (Corporate Names) and X11 (Meeting Names) fields for recording multiple location names in relation to conferences.Experimentation with a technique for including URIs for values (no MARC content designation change).
