An updated version of Candidate Music Genre/form Terms for Discussion [PDF, 5.9 MB] has been posted, incorporating relevant additions and changes to Library of Congress Subject Headings between February 2011 and January 2012.
The following updated list of terms represents the progress so far in the development of the genre/form portion of the music component of the thesaurus, Library of Congress Genre/Form Terms for Library and Archival Materials (LCFGT). LCGFT is being created in the Policy and Standards Division in the course of the Library’s implementation of field tags 155 and 655, genre/form terms, in the MARC 21 Bibliographic and Authority Formats, respectively.
This list contains terms for musical works derived from the Library of Congress Subject Headings, including headings (tag 150), form subdivisions (tag 185) and references (tag 150/260). It omits headings for musical works with subdivisions and headings that have parenthetical qualifiers containing medium of performance, because medium of performance terms appear in a separate list at the site (http://www.loc.gov/catdir/cpso/medprf.html).
A new feature beginning with this update of the list of terms assigned to musical works is the Status column, where decisions about individual terms are recorded. The decisions are the result of discussion between the LC Music Genre/Form Project Group and the MLA-BCC Genre/Form Task Force appointed by the Music Library Association. The principal issues are:
- the music genre/form vocabulary that should be in the thesaurus;
- the semantic relationships among the terms, given that they will be in a structured thesaurus;
- the syntax of headings that embody the terms, considering that these headings, while assigned in bibliographic records for musical works, will also co-exist in the thesaurus with headings in all fields that will be combined in this comprehensive vocabulary standard.
The center column in the list contains the LCCN of the candidate term. Eventually, terms accepted for the thesaurus will be turned into authority headings with a MARC 155 tag.
