OCLC-MARC Bibliographic, Authority, and Holdings Format Update 2015 will be installed in August 2015. All details are now available in OCLC Technical Bulletin 265: OCLC-MARC Format Update 2015 (https://www.oclc.org/support/services/worldcat/documentation/tb/265.en.html).
This update implements format changes announced by the Library of Congress in MARC 21 Updates No. 19 (October 2014;
http://www.loc.gov/marc/marc21_update19_online.html) and No. 20 (April 2015;
http://www.loc.gov/marc/marc21_update20_online.html), including:
- Defining code “q” (Lease) in the Holdings 008/07 (Method of Acquisition).
- Removing “university presses” as part of the definition of Government Publication in the Books, Computer Files, Continuing Resources, Maps, and Visual Materials Bibliographic 008/28 and 006/11
(GPub) elements.
- Implementing the First Indicator (Source of Acquisition Sequence), subfield $3 (Materials Specified), and subfield $5 (Institution to which Field Applies) in Bibliographic 037 (Source of Acquisition).
- Implementing subfields $q (Establishment Date) and $r (Termination Date), and redefining subfields $s (Start Period) and $t (End Period), in Authority 046 (Special Coded Dates).
- Broadening the scope of Bibliographic 088 (Report Number) to include series report numbers.
- Implementing Bibliographic 370 (Associated Place).
- Implementing subfield $e (Number of Ensembles) and making subfield $s (Total Number of Performers) Nonrepeatable in both the Bibliographic and Authority 382 (Medium of Performance) fields.
- Implementing Bibliographic and Authority 388 (Time Period of Creation).
- Invalidating the First Indicator in Bibliographic field 648 (Subject Added Entry: Chronological Term).
- Implementing field 884 (Description Conversion Information) in the Bibliographic, Authority, and Holdings formats.
- Implementing the repeatable subfield $g (Miscellaneous Information) or making it repeatable in some 22 Bibliographic fields and 24 Authority fields.
- Implementing subfield $i (Relationship Information) in thirteen 7XX Authority fields.
- Implementing subfield $4 (Relationship Code) in fourteen 7XX Authority fields.
We will also make additions to WorldCat indexing, validate all MARC Codes defined by the Library of Congress between July 2014 and June 2015, and implement subfields $8 (Field Link and Sequence Number) in some
46 Bibliographic fields.
OCLC plans to install the OCLC-MARC 2015 Update during August 2015 and will make announcements widely through the usual discussion lists and Connexion logon greetings at that time. Note that the implementation
of Authority format elements must be coordinated with the Library of Congress and the Program for Cooperative Cataloging and should not be used until LC, PCC, and OCLC announce that PCC testing of the new elements has been completed.
Please forgive any duplication of this message.
