OCLC has now installed changes related to the OCLC-MARC Update 2015. This update implements MARC 21 Bibliographic and Holdings format changes announced by the Library of Congress in MARC 21 Updates Number 19 (October
2014; http://www.loc.gov/marc/marc21_update19_online.html) and Number 20 (April 2015;
http://www.loc.gov/marc/marc21_update20_online.html), as well as all MARC codes announced by the Library of Congress between July 2014 and June 2015. In addition, OCLC has validated subfields
$8 (Field Link and Sequence Number) in some 46 Bibliographic fields.
All details are available in OCLC Technical Bulletin 265: OCLC-MARC Format Update 2015 (https://www.oclc.org/support/services/worldcat/documentation/tb/265.en.html).
Please note that the implementation of all MARC 21 Authority elements must be coordinated with the Library of Congress and the Program for Cooperative Cataloging. As noted in TB 265, Name Authority Cooperative
(NACO) participants should not attempt to use any of the Authority format changes at this time because they have not been installed or validated. LC, PCC, and OCLC will announce the implementation of these elements for use in name and subject authority records
at a future date.
Among the Bibliographic and Holdings format highlights of OCLC-MARC Update 2015 are:
- 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).
- 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 the Bibliographic 382 (Medium of Performance) fields.
- Implementing Bibliographic 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 and Holdings formats.
- Implementing the repeatable subfield $g (Miscellaneous Information) or making it repeatable in some 22 Bibliographic fields.
Please forgive any duplication of this message.
