About the Checklist
This checklist will focus on the two media types catalogers are most likely to encounter: audio discs (CD sound recordings primarily) and audiocassettes. RDA also addresses reel-to-reel tape, tape cartridges, piano rolls, and sound recordings on motion picture film, which are not covered here.
The checklist is in MARC 21 order. Citation numbers at the beginning of sections are the RDA instruction numbers followed by AACR2/rev. rule numbers. The checklist emphasizes descriptive/access elements that differ from standard book cataloging or are otherwise unique to sound recording cataloging. For description/access areas not addressed here--e.g. parallel titles, capitalization--refer to our Simple Book Local Workflow in the Tools section of the RDA Toolkit, as well as RDA Sections 2, 3, etc., the appendices, & the appropriate LC-PCC Policy Statements. Requirements beyond the core RDA elements are keyed to PCC BSR policy for audio recordings; any YUL differences will be noted.
The cataloger is responsible for deciding whether the sound recording is accompanying material or the primary resource. For example, if the cataloger decides that the printed resource is primary and the sound recording is accompanying material, the cataloger should catalog the resource as a text and not apply this checklist.
When to make a new record
For additional information, refer to OCLC Bibliographic Formats and Standards.
Make a new record:
1. For a different edition.
2. For a different format (CD vs. cassette)
3. When there are technical differences (300 ‡b), e.g. stereo vs. mono. Size differences (300 ‡c), e.g. CD vs. mini-CD.
4. If information in the publisher number  on the physical resource differs from the information in the 028 of the cataloging copy. However, the absence of the 028 field in the record when the publisher number is on the physical resource (or vice versa) does not require a separate record--all other things being equal.
Accompanying material (usually printed) is sometimes cataloged separately (but this is an option and most definitely not a requirement); in most cases the accompanying material will be recorded in 300 ‡e, a second 300 field, or in a 500 note. See also the section below, LCRI 1.5E1 Accompanying Material (300 ‡e).
