RDA

As of April 16, 2013, the rules on this page have been approved in concept by the SCRAP committee, but the exact wording is still being adjusted.
Please use these rules. Please send any feedback to SCRAP.

RDA, or Resource Description and Access, is a cataloging standard which is replacing AACR2. With the exceptions of local practices outlined within this wiki, we catalog according to national practice, which currently allows following either AACR2 or RDA; and we do full level cataloging, as defined in OCLC's Bibliographic Formats and Standards.

This change is being considered by the SCRAP committee.
Do NOT follow this change. Please send any feedback to SCRAP.

With the exceptions of local practices outlined within this wiki, including our RDA Policy Statements, we catalog according to national practice, which currently allows following either AACR2 or RDA; and we do full level cataloging, as defined in OCLC's Bibliographic Formats and Standards.

How to recognize an RDA record in OCLC

Fixed field, description code is i or c.

040 includes ‡e rda.

There are no abbreviations in non-transcribed fields, and any abbreviations in transcribed fields are found that way on the original item.

The 245 lacks a GMD.

There are additional fields present to represent the concepts that are in the GMD under AACR2.

336 - rdacontent

337 - rdamedia

338 - rdacarrier

(Note that the presence of 336, 337, and 338 fields alone does not indicate that a record is an RDA record, as these may legitimately be added to records that are otherwise cataloged according to AACR2.)

What to do with RDA records

In WorldCat, nothing special.

In CCS, review them to the best of your ability, utilizing the RDA toolkit. Add the GMD (|h) and qualifier to appropriate records. Use the authorized form of names found in the OCLC authority file.

How to recognize RDA-AACR2 hybrid records

It is appropriate for AACR2 records to contain any or all of the following RDA-based content:

  • Addition of ‡e relator terms to access points
  • Spelling out non-transcribed abbreviations
  • Adding complete statements of responsibility instead of using "[et al.]"
  • Adding 336, 337, and 338 fields

These are the most common indications that a record may be an inappropriate hybrid of AACR2 and RDA rules:

  • If the fixed field, Description code is "a" on a record that contains 040 ‡e rda.
  • In the fixed field, Description code is "i" on a record that lacks 040 ‡e rda.
  • If 040 ‡e rda is present in record that contains abbreviations, uses "[et al.]" for statements of responsibility, or lacks 336, 337, and 338 fields
  • If an RDA record has a GMD.
  • If an AACR2 record lacks a GMD.

What to do with RDA-AACR hybrid records

For appropriate hybrid records, leave as is, whether in CCS or in WorldCat.

For inappropriate hybrid records in WorldCat, either correct & upgrade it to a full RDA record, or submit an error report for the record.

For inappropriate hybrid records in CCS, check to see whether the record has been fixed in WorldCat. If not, either correct it in WorldCat and then overlay the local record, or fix the local record so that it is internally consistent.

Merging duplicate records

When there are duplicate records in the CCS database, and at least one is cataloged according to RDA, prefer the better, more complete record. If the preferred record is not an RDA record, please add the relevant RDA fields to the preferred record.
