About the Music Toolkit: The Music Toolkit, developed by Gary Strawn based on specifications provided by the CMC Vocabularies Subcommittee, analyzes 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.
