RDA (Resource Description and Access) is a new system of cataloging rules that is replacing AACR2. Full training and documentation are planned, but, since RDA records are becoming quite common in OCLC, this preliminary list should help you to identify and deal with RDA records found during the transition.
|Fixed Field||The Fixed Field elements are largely unchanged.|
|0XX||The 0XX fields (numeric identifiers and classification) are largely unchanged. Continue to apply current procedures.|
|040||RDA records are identified by the presence of |erda in 040; this will alert you to the possible presence of new fields, subfields, and other changes within the record.|
|1XX||The author elements, for both corporate and personal names, are largely unchanged. You may notice a profusion of |e subfields, which are relator terms describing the person or body’s role – for example, author, illustrator, editor, publisher, cartographer. Accept |e on copy unless obviously wrong. The subfield is repeatable, meaning that a name may have multiple terms associated with it; accept as found.|
|245||Title field is largely unchanged, but the GMD (subfield |h) is no longer included.|
The edition statement is largely unchanged, although it is now transcribed, meaning “edition” will be spelled out, unless it is abbreviated on the piece.
|260||Field 260 may not be present in RDA copy; don’t panic. It’s probably still a valid record. 260 has been replaced by 264. When there is no 260, look for the 264; one or the other should be present.|
Field 264 is used in RDA records instead of field 260 as the home of publication, distribution, manufacturing, and copyright information.
Accept field 264 on copy, treating 264 the same way you would 260 for matching.
264 #1 University Park, PA :|bThe Pennsylvania State University,|c 2012.
264 #1 Boston :|b[publisher not identified],|c2010.
Field 300 is largely unchanged, except that many words are now spelled out.
300 ## 225 pages :|billustrations, maps ;|c21 cm.
The GMD (245 |h) has been replaced by three new fields:
These fields are repeatable and may be used to describe accompanying material as well as the main item. Accept as found unless obviously wrong.
|4XX||Field 490 includes the series title transcribed from the item; there is no significant change in how these are handled, except that the series numbering is recorded as it appears on the resource (spelled out or abbreviated). Continue to apply current procedures.|
|5XX||There are no significant changes in the key 5XX fields; verify, accept, or add as usual.|
|6XX||There are no significant changes in subject fields.|
|7XX||The added entries are largely unchanged; as in 1XX, expect an increase in relator terms in |e. Accept on copy unless obviously wrong.|
|8XX||The 8XX includes the authorized form of the series title; there is no significant change in how these are handled. Continue to apply current procedures.|
