ALCTS White Paper on Faceted Vocabularies


Please excuse duplication. This announcement is being distributed to several lists. Please share with your colleagues.


The ALCTS CaMMS Subject Analysis Committee announces the approval and release of a white paper, “A Brave New (Faceted) World: Towards Full Implementation of Library of Congress Faceted Vocabularies.” The full text of the white paper can be downloaded from the ALA Institutional Repository (ALAIR).

Prepared by the Working Group on Full Implementation of Library of Congress Faceted Vocabularies, ALCTS/CaMMS Subject Analysis CommitteeSubcommittee on Genre/Form Implementation, this document summarizes the development of faceted vocabularies by the Library of Congress in collaboration with the ALCTS CaMMS Subject Analysis Committee and several specialized cataloging communities. It contains suggestions and recommendations for next steps aimed at full-scale current and retrospective implementation of faceted vocabulary terms in bibliographic and authority metadata.

The vocabularies described in this document are the Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT), the Library of Congress Medium of Performance Thesaurus (LCMPT), and the Library of Congress Demographic Group Terms (LCDGT). Although they are discussed in terms of MARC, these vocabularies represent a step forward as a bridge from MARC to emerging metadata formats such as BIBFRAME and to the linked data environment in general.




Best Practices for Using LCMPT–new version now available


The MLA Vocabularies Subcommittee is pleased to offer a new version of the document Best Practices for Using LCMPT. In addition to a number of minor formatting and stylistic updates, the following new content is incorporated:

  1. Guidance for use of the new 382 subfields $r and $t
  2. Expanded guidance on “bi-level” medium statements
  3. Expanded guidance on partial medium statements
  4. Clarification on polychoral situations

As always, feedback and questions can be directed to me ( Additionally, the new revision will be briefly discussed at the VS business meeting and at the CMC Town Hall at MLA Orlando.

I wish to thank the VS task group who prepared this revision, amidst a shifting landscape of MARC format updates and evolving practices with faceted vocabularies.

OCLC Search & Discovery Task Force Report available

[This message is being cross-posted widely. Please excuse duplication]


Shortly after the 2015 annual meetings of the Music Library Association and the Music OCLC Users Group in Denver, MLA President Michael Rogan and (then) MOUG Chair Bruce Evans empaneled a joint task force with the following charge:

“Investigate OCLC’s WorldCat Discovery Services to determine if it will be sufficient to meet the needs of music users. If the Task Force determines that WorldCat Discovery Services is not sufficient, it will recommend a course of action to petition OCLC to continue to provide the FirstSearch interface for WorldCat after December 31, 2015. It will also recommend a course of action to petition OCLC for specific improvements to WorldCat Discovery Services to meet the needs of music users.”

The Joint MLA/MOUG OCLC Search and Discovery Task Force submitted its report to both Boards in May 2016. With only very minor revisions, it was ratified by both Boards. We owe the Task Force our immense gratitude for successfully fulfilling their charge and producing such an excellent and thorough report, which will provide a framework for seeking these improvements for years to come.

Last week, the report (available here) along with a cover letter (available here) was sent to select OCLC management staff, including CEO Skip Prichard. As of this writing, we have already received a response from Mary Sauer-Games, Vice President, Global Product Management, who states the following:

“The OCLC Search and Discovery Task Force Report is particularly timely, given the recent announcement that we will build a new version of FirstSearch. That new version will deliver the full-featured WorldCat searching valued by many FirstSearch users, including expert searchers in the music library community. Your recommendations will be helpful as we move forward with that product, as well as enhancements to search features in WorldCat Discovery. Several of your recommendations have also been requested by other community members and are already under consideration and prioritization by our WorldCat Discovery team.”

The full announcement from OCLC regarding the new version of FirstSearch is available here.

The MOUG Board plans to meet with select OCLC staff during its Board meeting in Columbus, Ohio early next month, with the objective of following up on this response in more detail. We are encouraged by this immediate response from OCLC and hope that it, like the decision regarding a renewed life for FirstSearch, reflects a growing awareness of all users’ needs. MLA and MOUG will continue both to advocate strenuously for these improvements and to work in cooperation with OCLC toward solutions that work for the music community.

Please don’t hesitate to contact Michael or myself with any questions or comments.

Best Practices for Using LCMPT (newly revised and expanded!!)


I’m pleased to announce the release of the expanded, revised 2016 edition of the document Best Practices for Using LCMPT. Based on feedback from the community and over a year of collective experience applying LCMPT terms in cataloging since the release of the vocabulary, this revision is considerably more robust than the original “provisional” version of the document.

Detailed guidance is now present for the following areas:

  • 382 subfields e and v
  • Continuo
  • Electronics
  • Operas and other dramatic works
  • Percussion
  • Separately-manifested parts
  • The terms “singer” and “voice”
  • The terms “string orchestra” and “bowed string ensemble”

There are also significantly more examples in this revised version. And content has been harmonized with the parallel document Best Practices for Using LCGFT for Music Resources.

I would like to heartily thank the working group within the Vocabularies Subcommittee who painstakingly prepared this revision, as well as numerous other CMC members who offered feedback during the drafting process. Feedback is welcome, and will be taken under advisement for future revisions of the document; please send all comments and questions to

Looking forward to seeing many of you next week!



Chair, MLA Vocabularies Subcommittee
