About Technical Bulletin 269
Why read this?
To learn about changes to OCLC-MARC records, many of which are related to Resource Description Access (RDA). These changes are based on:
- MARC 21 Format for Bibliographic Data Update 27 (November 2018)
- MARC 21 Format for Authority Data Update 27 (November 2018)
- MARC 21 Format for Holdings Data Update 27 (November 2018)
- MARC Code List Technical Notices
- Comments and requests from OCLC users and staff
Record processing information
All sections describe changes that may affect local system processing of OCLC-MARC records.
Route to
Cataloging and local system or automation staff.
Online installation
May 2019, unless otherwise noted. Installation of this OCLC-MARC Update will be announced via logon Messages of the Day, Connexion News, and the OCLC-CAT discussion list.
OCLC strongly recommends not using new capabilities, new fields and subfields, new indicators, new practices, and new codes until OCLC announces that they may be used.
New fields, subfields, and indicators: These may be used in Record Manager and both Connexion interfaces after OCLC announces that they may be used.
Name Authority Cooperative (NACO) participants should not use the authority format changes in Authority Record Changes at this time. The Library of Congress and OCLC will announce the implementation of these elements for use in name and subject authority records at a future date.
New codes: These may be used in Record Manager and both Connexion interfaces after OCLC announces that they may be used.
New searching and indexing capabilities: All new searching and indexing capabilities will be available in both Connexion interfaces (client and browser) in the future. OCLC will announce availability via logon Messages of the Day, Connexion News, and the OCLC-CAT discussion list. After installation, all indexing changes will gradually become apparent as WorldCat is re-indexed.
Database scans
OCLC will convert, or has converted, data to their new formats where appropriate to the extent that is possible.

Bibliographic Record Changes
041 Language Code (R)
| New subfields | ‡p | Language code of captions (R) Language codes for language used in moving image resource captions, whether open captioning (Subtitles for the Deaf and Hard of Hearing (SDH)) or closed captioning (CC). |
| ‡q | Language code of accessible audio (R) Language codes for audio used as an alternative mode of access to the visual or textual content of a resource. For example, Described Video, a supplementary audio track providing additional access to moving image visual content using audio description. |
|
| ‡r | Language code of accessible visual language (non-textual) (R) Language codes for visual languages (non-textual) used to provide alternative access to the audio content of a resource. For example, signed languages. For resources where signed language is the primary mode of access, subfield ‡a should be used to record the language code for signed language. |
|
| Subfield definition revised | ‡a | Language code of text/sound track or separate title (R) For moving image resources, subfield ‡a contains the code(s) of spoken or sung languages associated with the item, as well as sign language and any language code(s) of the languages of accompanying sound. Code languages used to provide access to a resource in an alternative (accessible) mode as appropriate in either subfields ‡p, ‡q, or ‡r. |
| Subfield renamed and redefined | ‡j | Language code of subtitles (R) Formerly, Language code of subtitles or captions (R) New definition: Language codes for written languages providing access to moving image materials, such as intertitles (silent films) and subtitles. It does not include the languages of the credits, packaging, or accompanying material. If needed, the language of credits is recorded in field 546 (Language Note) and the language of packaging or accompanying material is recorded in 041 subfield ‡g (Language code of accompanying material other than librettos). Former definition: Language codes for written languages included in moving image materials, such as intertitles (silent films), subtitles, or captions (open or closed, intended for users with hearing disabilities). It does not include the languages of the credits, packaging, or accompanying material. If needed, the language of credits is recorded in the field 546 and the language of packaging or accompanying material is recorded in 041 subfield ‡g. |

Each occurrence of the field requires one subfield ‡a to record the mode of access for which an alternative mode is provided and one or more ‡b–‡e subfields identifying the type of alternative access. Values for subfields ‡b–‡e should be taken from the same controlled vocabulary. Multiple values from the same source vocabulary may be recorded in the same field in separate occurrences of subfields. Terms from different source vocabularies are recorded in separate occurrences of the field. |

532 Accessibility Note (R)
| New field | ||
| Definizione | Textual information describing the accessibility features, hazards, and deficiencies of a resource, including technical details relating to accessibility features. This field may be used to expand on or to qualify data in field 341 (Accessibility Content). | |
| 1st indicator | Display constant controller Controls the generation of an introductory phrase. |

Subfield ‡6 (Linkage (NR))
| Subfield redefined | ‡6 | Linkage (NR) Scope of ‡6 broadened to allow for the recording of script identification codes taken from ISO 15924. OCLC-MARC Bibliographic already accommodates the four-alphabetic-character values taken from ISO 15924 in Control Subfield ‡6. OCLC-MARC Bibliographic does not currently accommodate the three-digit numerical values taken from ISO 15924. In WorldCat, subfield ‡6 is always system-supplied, is never created manually, and does not appear in online displays. As such, accommodation of the ISO 15924 three-digit numerical values within WorldCat remains under consideration. |
Authority Record Changes
Name Authority Cooperative (NACO) participants should not use the authority format changes listed below at this time. The Library of Congress and OCLC will announce the implementation of these elements for use in name and subject authority records at a future date.
055 Library and Archives Canada Call Number (R)
| Field definition and scope revised | Call number for a series assigned in Canada if the institution has classified all or part of the series as a collected set, or with a main series, e.g. field 646 (Series Classification Practice), subfield ‡a, code c or m. Field 055 may also contain the volumes/dates to which the number applies. Varying numbers for different ranges of volumes/dates within a series or different copies or sets are contained in separate 055 fields. Note that call numbers/class numbers to be recorded in field 055 include those assigned from the Library of Congress classification schedules, and those from schedules specially developed by Library and Archives Canada for Canadian history and literature. |
|
| New subfield | ‡2 | Number source (NR) Source list or scheme from which the call/class number was assigned. Code from Classification Scheme Source Codes. |
Subfield ‡6 (Linkage (NR))
| Subfield redefined | ‡6 | Linkage (NR) Scope of ‡6 broadened to allow for the recording of script identification codes taken from ISO 15924. Subfield ‡6 has not been implemented in the OCLC-MARC Authority format. Where subfield ‡6 has been implemented in OCLC-MARC, the subfield already accommodates the four-alphabetic-character values taken from ISO 15924. OCLC-MARC does not currently accommodate the three-digit numerical values taken from ISO 15924. In WorldCat, subfield ‡6 is always system-supplied, is never created manually, and does not appear in online displays. As such, accommodation of the ISO 15924 three-digit numerical values within WorldCat remains under consideration. |
Holdings Record Changes
Subfield ‡6 (Linkage (NR))
| Subfield redefined | ‡6 | Linkage (NR) Scope of ‡6 broadened to allow for the recording of script identification codes taken from ISO 15924. Subfield ‡6 has not been implemented in the OCLC-MARC Holdings format. Where subfield ‡6 has been implemented in OCLC-MARC, the subfield already accommodates the four-alphabetic-character values taken from ISO 15924. OCLC-MARC does not currently accommodate the three-digit numerical values taken from ISO 15924. In WorldCat, subfield ‡6 is always system-supplied, is never created manually, and does not appear in online displays. As such, accommodation of the ISO 15924 three-digit numerical values within WorldCat remains under consideration. |
