Greetings, Connexion users!

Current and future users of the OCLC Music Toolkit are encouraged to
download the updated installer from
http://files.library.northwestern.edu/public/Music382/. Updates in the
October 24, 2018 version include:

   - 382/LCMPT
      - LCSH “harp” mapping changed, to LCMPT “pedal harp”
      - LCSH “[Instrument] $v Studies and exercises” and “[Instrument] $v
      Studies and exercises, Juvenile” generates LCMPT for solo instrument
      - LCSH subdivisions “Excerpts” and “Excerpts, Arranged” do not
      prevent generation of field 382 for medium in $a
      - Calculation of number subfields: added terms ending in “orchestra”
      or “choir” to terms considered an ensemble
      - Calculation of number subfields: confirmed that $r adds number from
      $b and $a (soloists and non-soloist individual performers, when ensemble
      involved) [no change]
   - 655/LCGFT
      - LCSH “Memorial music” mapping changed, from “Functional music” to
      “Memorial music”
      - LCSH “Romances (Music)” mapping added, to “Romances (Music)”
      - Comp (008/18-19; 006/01-02) mappings:
         - cn mapping added, to “Canons (Music)”
         - nc mapping changed, from “Art music” to “Nocturnes (Music)”
         - ft mapping changed, from “Art music” to “Fantasias (Music”)
         - cz mapping changed, from “Art music” to “Canzonas (Instrumental
         music)”
         - ri mapping changed, from “Art music” to “Ricercars”
      - Prevent Toolkit from overwriting fields 600-651 (fix: corrupted
   subject headings)
   - Replace MARC-8 in returned text with Unicode
   - “Notated music” bug fix
   - Known issues:
      - Incorrect rendering of special characters in 370 derived from 65x;
      catalogers are urged to check and correct fields when special
      characters/diacritics other than acute, umlaut, or cedilla are present.
      (Catalogers are urged to routinely check *all* generated data, but
      these are particularly critical.)

Feedback received through the form monitored by MLA's CMC [Cataloging and
Metadata Committee] Vocabularies Subcommittee is used to identify specific
features added or corrected in each update; programmer Gary Strawn then
incorporates these into the programming and OCLC macro. Music Toolkit users
are encouraged to continue to submit suggestions
<https://goo.gl/forms/P0rbGQfxaGIMtrba2> as they arise.

About the Music Toolkit: The Music Toolkit, developed by Gary Strawn (of
Authority Toolkit fame), is an OCLC macro that incorporates a program
written by Strawn which analyzes existing bibliographic data and generates
corresponding faceted terms from the Library of Congress Medium of
Performance Thesaurus (LCMPT), Library of Congress Genre/Form Terms (LCGFT),
and Library of Congress Demographic Group Terms (LCDGT), as well as other
faceted metadata such as dates and geographic place names. The Toolkit
output is then evaluated and adjusted as necessary by the cataloger, who is
responsible for correct application of LC faceted terms and their
corresponding MARC fields and, if desired, OCLC WorldCat master record
replacement. For more information on the Music Toolkit, please see the
April 18, 2018 CMC blog post, “New OCLC Music Toolkit for generating
faceted music data
