OCLC has now implemented changes related to the OCLC-MARC Update 2014, Phase Two.  This includes the remainders of the MARC 21 Bibliographic, Authority, and Holdings Updates No. 16, 17, and 18, as well as all MARC codes announced by the Library of Congress between April and June 2014.  Details can be found in OCLC Technical Bulletin 264 (http://www.oclc.org/support/services/worldcat/documentation/tb/264.en.html).  The OCLC-MARC Update 2014, Phase One was implemented in May 2014, covering selected elements of MARC 21 Update No. 16 (dated April 2013) and MARC code list additions announced by LC through March 2014.  Details of Phase One are available in OCLC Technical Bulletin 263 (http://www.oclc.org/support/services/worldcat/documentation/tb/263.en.html). 

Highlights of OCLC-MARC Update 2014, Phase Two include:

• New subfields $q (Qualifying Information) in Bibliographic (and Authority and Holdings, where applicable) fields 015, 020, 024, and 027.
• New subfields defined for Bibliographic and Authority 046 field.
• Subfields $c (Location of Meeting) made repeatable in Bibliographic and Authority X10 and X11 fields.
• New Authority X62 fields for Medium of Performance Terms.
• New Bibliographic and Authority fields 385 (Audience Characteristics) and 386 (Creator/Contributor Characteristics).
• New First Indicators for the Bibliographic 588 field.
• New Authority fields 672 (Title Related to the Entity) and 673 (Title Not Related to the Entity).
• New subfields $7 (Control Subfield) in Bibliographic 8XX fields.

Please note that the implementation of the Authority elements must be coordinated with the Library of Congress and the Program for Cooperative Cataloging.  As noted in TB 264, Name Authority Cooperative (NACO) participants should not use the Authority format changes at this time.  LC, PCC, and OCLC will announce the implementation of these elements at a future date.
