Note that fields 020, 024, & 028 are covered by RDA 2.15 Identifier for Manifestation, and are RDA core.
024 Other Standard Identifier
The identifiers most likely to be associated with sound recordings would be assigned first indicator 0 or first indicator 1
First indicator 0: ISRC (International Standard Recording Code) The number is usually preceded by "ISRC" and consists of 12 alphanumerics organized into 4 elements separated by hyphens on the item. The initials ISRC and the hyphens are not entered.
Code appears on item as: ISRC NL-C01-84-13261
Enter as:
| 024 | 0 | ‡a NLC018413261 |
First indicator 1: UPC (Universal Product Code) Appears as a barcode with 12 digits printed below (not to be confused with the ISBD number). The digits should be entered without spaces:
| 024 | 1 | ‡a 987654321098 |
There is a UPC image and more detail regarding ISRC and UPC on the BFAS page.
028 [Publisher number]
First indicator. 0 <issue number>. Other indicators apply to LP pressings (2) or printed music.
Second indicator. 1 <to support identification use second indicator 1; only indicator 1 will cause the number to display with the label Issue number: in the OPAC>
‡a Transcribe the publisher number as found, with the same spaces and hyphens used on the resource. [RDA 2.15.1.4 (formerly LCRI 6.7B)] If the set is multipart, record only the set number. If there is no set number, the publisher number for each part is recorded in a separate 028 field. Note that there are specific instructions for recording music publisher numbers under 2.15.2 that are not applied to non-music sound recordings.
‡b Label name. <generally but not necessarily the same as the publisher name>
EXAMPLES: Label name is the same as the publisher name. Reminder: in RDA copyright date is never transcribed in the publication statement.
| 028 | 0 | 1 | ‡a NA242512 ‡b Naxos AudioBooks |
| 264 | 1 | ‡a Franklin, TN : ‡b Naxos AudioBooks, ‡c [2006] |
| 028 | 0 | 1 | ‡a 645-646 ‡b Teaching Company |
| 264 | 1 | ‡a Chantilly, Va. : ‡b Teaching Co., ‡c [2002] |
EXAMPLE. Label name differs from publisher name.
| 028 | 0 | 1 | ‡a SLD 693 ‡b Sound Library |
| 264 | 1 | ‡a Hampton, NH : ‡b BBC Audiobooks America, ‡c [2004] |
041 [Language code] Keep in mind that a sound recording of a translation requires 041 ‡h, e.g. a recording of Chekhov's Uncle Vanya (in English translation). Mandatory for BSR RDA if more language codes are required than 008 allows.
In the example, note that MARC uses ‡d for the language of spoken text.
| 041 | 1 | ‡d eng ‡h rus |
050 _4 [Library of Congress Call Number] Assign LC classification number following the same criteria used for a printed text. If necessary, differentiate from the printed version by adding a work letter to the date.
FYI: sound recording numeric/control fields not required in core or used only in music sound recordings: 033 (Date/Time of Recording), 045 (Date/Time Coverage), 047 (Multiple Forms of Composition), 048 (Medium of Performance)
