About Technical Bulletin 262

Why read this?

To learn about changes to OCLC-MARC records, many of which are related to Resource Description and Access (RDA). These changes are based on:

  • MARC 21 Format for Bibliographic Data Update 15 (September 2012)
  • MARC 21 Format for Authority Data Update 15 (September 2012)
  • MARC 21 Format for Holdings Data Update 15 (September 2012)
  • 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.

Cataloging and local system or automation staff.

Online Installation

Installations of this OCLC-MARC Update will occur in stages, which OCLC will announce via logon Messages of the Day, Connexion News, and the OCLC-CAT listserv.

New fields, subfields, and indicators: These may be used in both Connexion interfaces now, with two exceptions:

  1. The bibliographic 883 field is being implemented in Connexion for possible future use. Do not use field 883 at this time.
  2. NACO participants should not input the new subfields in the authority 368 field until an announcement regarding their use is made by the Program for Cooperative Cataloging.

New codes: These may be used in both Connexion interfaces now.

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 listserv.

After installation, all indexing changes will gradually become apparent as WorldCat is re-indexed.

Database scans

OCLC will convert data to its appropriate new format to the extent that is possible.

1 Bibliographic Record Changes

FMus Format of Music (SCO 008/20 & 006/03)

Changed code definition for SCO format c Accompaniment reduced for keyboard.

Score with instrumental accompaniment reduced for keyboard(s). For chorus scores and vocal scores prefer codes h (Chorus score) and k (Vocal score).
  d Voice score with accompaniment omitted.

Score for solo and/or choral voice(s) with the accompaniment omitted. Vocal works originally unaccompanied are assigned other codes as appropriate. For chorus scores and vocal scores, prefer codes h (Chorus score) and k (Vocal score).
  h Chorus score.

Score of a work for solo voices and chorus showing only the parts for chorus, with the instrumental accompaniment either arranged for keyboard(s) or other chordal instrument(s) or omitted. Note: See code k (Vocal score) for scores that include solo voices as well as chorus parts.
New code k Vocal score.

Score showing all vocal parts, solo and/or choral, with the instrumental accompaniment either arranged for keyboard(s) or other chordal instrument(s) or omitted. Note: See code h (Chorus score) for scores of works for solo voices and chorus that include only chorus parts.

024 Other Standard Identifier (R)

ISMN - International Standard Music Number redefined   ISMN is an agency-assigned data element. ISMNs are assigned to music publications by designated agencies in each country participating in the program.

An ISMN consists of ten or thirteen digits. The 10-digit ISMN, used before 2008, is comprised of the letter M followed by 8 digits (variable length publisher number plus item number) plus a single character check digit. The check digit applies to the previous 8 digits.

The 13-digit ISMN, used since 2008, has the prefix 979 and a to replace the M, then 8 digits plus the final check digit. The check digit applies to the previous 12 digits. A 13-digit ISMN is identical to the EAN-13 number encoded in the bar code. The structure is specified in ISO 10957.

An ISMN usually appears on an item preceded by the initialism ISMN and with functional parts separated by a hyphen or space. Enter the ISMN without hyphens or spaces.
New 1st indicator coding practice   All ISMNs (both 10 and 13-digit) should be coded with a first indicator value of 2.

028 Publisher Number (R)

New subfield ‡q Qualifying information (R)

Contains qualifiers associated with the number such as part to which number pertains, where number found on item, etc.
Printing display constants changed   For 1st indicator value or 1, the print program changes the order of the subfield data before printing (i.e., the data in subfield ‡b precede the data in subfield ‡a, which precede the data in subfield ‡q). It supplies a colon and a space between the name in subfield ‡b and the number in subfield ‡a, a space between the number in subfield ‡a and the parenthetical data in subfield ‡q, and a period at the end of the note.

If the 1st indicator value is and field 028 is:
028 02 K2 31158 ‡b EMI Music Canada ‡q (on label)

Then field 028 prints as the first note:
EMI Music Canada: K2 31158 (on label)

If the 1st indicator value is 1, 2, or 3, the print program supplies a period at the end of the note:
028 32 12 0575 07 01 ‡n Novello ‡q (parts)

Then field 028 prints as the last note:
Publisher's no.: 12 0575 07 01 (parts).

If you want to print a note but you cannot provide it from field 028 (e.g., if multiple numbers are to print as a range), use 2nd indicator value or 3 and enter the note in field 500.

041 Language Code (R)

Changed definition   Field 041 may also be used to express the original language of the work
Changed VIS guideline   Field 041 may also be used to record additional language-related information about written or original languages on motion pictures and videorecordings.

082 Dewey Decimal Classification Number (R)

Indexing   Subfields ‡a, ‡b, ‡m, ‡q, and ‡2 will be indexed in the new Dewey General index (d6:).

Indexing changes will be available in the future. OCLC will announce availability of indexing changes via logon Messages of the Day, Connexion News, and the OCLC-CAT listserv.

083 Additional Dewey Decimal Classification Number (R)

Indexing   Subfields ‡a, ‡c, ‡y, and ‡z will be indexed in the new Dewey Additional index (d3:).

Examples
‡a 003.52 indexed as: 003.52
‡z 1 ‡a 01 indexed as: 1--01

‡a 155 ‡y 1 ‡a 2 indexed as: 155:2
‡a 264.04 ‡c 264.09 ‡y 1 ‡a 09 indexed as: 264.04-264.09:09

Subfields ‡a, ‡c, ‡y, and ‡z will be indexed in the new Dewey General index (d6:).

Indexing changes will be available in the future. OCLC will announce availability of indexing changes via logon Messages of the Day, Connexion News, and the OCLC-CAT listserv.

085 Synthesized Classification Number Components (R)

Indexing   Subfields ‡c, ‡r, ‡w, and ‡z, as well as ‡s and ‡t will be indexed in the new Dewey Component index (d5:).

Examples
‡z 1 ‡s 01 indexed as: 1--01
‡r 003 ‡s 52 indexed as: 003.52

‡w 155 ‡y 1 ‡t 2 indexed as: 155.2
‡w 264.04 ‡c 264.09 ‡y 1 ‡t 09 indexed as: 264.04-264.09:09

Subfields ‡a, ‡b, ‡c, ‡r, ‡s, ‡t, ‡u, ‡v, ‡w, and ‡z will be indexed in the new Dewey Full index (d4:).

Subfields ‡a, ‡b, ‡c, ‡r, ‡s, ‡t, ‡u, ‡v, and ‡w are indexed in the new Dewey General index (d6:). Pattern: Combine Dewey Decimal class number (dd:), Dewey Additional (d3:), and Dewey Full (d4:) indexes. Note: The Dewey Component (d5:) index is a subset of the Dewey Full index (d4:).

Note on subfield ‡s. If there is no subfield ‡z but subfield ‡r is present, a period is inserted the after third digit of subfields ‡r and ‡s. If there is no subfield ‡z and no subfield ‡r present, zeros are added to subfield ‡s until it is three digits long.

Note: 085 fields derived from editorially-created 765 fields in MARC Classification records will not include subfield ‡v, but 085 fields provided by other parties might.

Indexing changes will be available in the future. OCLC will announce availability of indexing changes via logon Messages of the Day, Connexion News, and the OCLC-CAT listserv.

Definition   Used to provide information about the provenance of metadata in data fields in the record, with special provision for machine generation. Field 883 contains a link to the field to which it pertains. Intended for use with data fields that have been fully or partially machine-generated, i.e., generated by some named process other than intellectual creation.

Identifies the process used to produce the data contained in the linked field. The subfield may contain a process name or some other description.
  ‡c Confidence value (NR)
Describes the confidence of the agency using the process/activity identified in subfield ‡a to generate the linked field. The subfield contains a floating point value between and 1. Either a comma or a point may be used as a decimal marker. means no confidence and 1 means full confidence.
  ‡d Generation date (NR)
Date on which the linked field was generated. This also serves as the beginning of the period of validity. Date is recorded in the format yyyymmdd in accordance with ISO 8601, Representation of Dates and Times.
  ‡q Generation agency (NR)
MARC organization code of the institution using the process/activity to generate the linked field. Code from: MARC Code List for Organizations (http://www.loc.gov/marc/organizations/).
  ‡x Validity end date (NR)
Date representing expected end of period of validity for the data in the linked field. Date is recorded in the format yyyymmdd in accordance with ISO 8601, Representation of Dates and Times.
  ‡u Uniform Resource Identifier (NR)
Uniform Resource Identifier (URI), for example a URL or URN, which identifies the process used to produce the data contained in the field to which 883 is linked. The URI can lead to a textual or structured description of the process, or the URL that was used to generate the linked field's content can be provided directly, i.e., a URL invoking a web service or conveying an API call.
  ‡w Bibliographic record control number (R)
Control number of the bibliographic record from which the data in the linked field was obtained.
  ‡0 Authority Record Control Number or Standard Number (R)
Subfield ‡0 contains the system control number of the related authority record, or a standard identifier such as an International Standard Name Identifier (ISNI). The control number or identifier is preceded by the appropriate MARC Organization code (for a related authority record) or the Standard Identifier source code (for a standard identifier scheme), enclosed in parentheses. See MARC Code List for Organizations ( http://www.loc.gov/marc/organizations/) for a listing of organization codes and Standard Identifier Source Codes ( http://www.loc.gov/standards/sourcelist/standard-identifier.html) for code systems for standard identifiers. Subfield ‡0 is repeatable for different control numbers or identifiers. Note: Do not input subfield ‡0 in master records, instead use the control headings function. Local authority identifiers may be entered in subfield ‡0 locally, but should not be added to master records in WorldCat.
  ‡8 Field Link and Sequence Number (R)
Identifies linked fields and may also propose a sequence for the linked fields. Subfield ‡8 may be repeated to link a field to more than one other group of fields. You are responsible for creating and maintaining the link (The system does not create or maintain these links). The structure and syntax for the field link and sequence number subfield is:

‡8 [linking number].[sequence number]\[field link type]

Note: Subfield ‡8 is defined differently in field 852, where it is used to sequence related holdings records.

Subfield ‡8 has three parts:

Linking number is the first data element in the subfield and required if the subfield is used. It is a variable-length whole number that occurs in subfield ‡8 in all fields that are to be linked. Fields with the same linking number are considered linked.

Sequence number is separated from the linking number by a period '.' and is optional. It is a variable-length whole number that may be used to indicate the relative order for display of the linked fields (lower sequence numbers display before higher ones). If it is used it must occur in all ‡8 subfields containing the same linking number.

Field link type is separated from preceding data by a reverse slash '\'. It is a code indicating the reason for the link and it follows the link number, or sequence number if present. Field link type is required except when ‡8 is used to link and sequence 85X-87X holdings fields. The following one-character field link type codes have been defined in MARC for use in subfield ‡8.
Field link type codes a Action
Links one or more fields with another field to which the processing or reference actions relate. This code is typically used only when there is more than one 5xx field that relates to another 5xx field.
  c Constituent item
Used in a record for a collection, or a single item consisting of identifiable constituent units, to link the fields relating to the constituent units. All other non-linked data elements in the record pertain to the collection or item as a whole.
  p Metadata provenance
Used in a record to link a field with another field containing information about provenance of the metadata recorded in the linked field.
  r Reproduction
Used in a record for a reproduction to identify fields linked because they contain information concerning only the reproduction. Other descriptive information in the record pertains to the original (with the exception of field 007 (Physical Description Fixed Field), 008 (Fixed-Length Data Elements: Books, Music, Serials, or Mixed Material) position 23 (Form of item), field 245 subfield ‡h (Title Statement / Medium), and field 533 (Reproduction Note)).
  x General sequencing
Used in a record to make a link between fields to show a sequence between them. The sequence could be one that orders the pieces of a long field that has been broken up, indicates the relative importance of fields within the sequence, or is used for some other sequencing purpose. Use of the sequence number in ‡8 is required when this code is used.
Indexing   Subfields ‡a, ‡u will be indexed in the Generation Process index (gp: and gp=).
Subfield ‡q will be indexed in the Generation Agency index (ga=).

Indexing changes will be available in the future. OCLC will announce availability of indexing changes via logon Messages of the Day, Connexion News, and the OCLC-CAT listserv.

994 OCLC-MARC Transaction Code (NR)

    Field 994 has been used since 1999, but is now added to Bibliographic Formats and Standards.
Definition   Field 994 contains the codes that identify the transaction that created the record. Field 994 is system generated on export or OCLC-MARC record output. This field cannot be edited or input manually. Note: In OCLC MARC Records, this field has been documented as "OCLC-MARC Processing Information."
History   Before June 6, 1999, transaction codes were stored in Leader byte 22 (Transaction Type Code).

From June 6, 1999-December 31, 1999, transaction codes were stored in field 994 and Leader byte 22. Note: This was the transitional period during which field 994 was implemented in various OCLC products and services at various times. Transaction codes continued to be stored in Leader byte 22 during this time.

From January 1, 2000-November 11, 2006, transaction codes were stored in field 994 and Leader byte 22.

From November 12, 2006-present, transaction codes were stored in field 994. Note: Connexion client 1.60 used both field 994 and Leader byte 22 until it was discontinued on April 1, 2007.
