Virtual International Authority File

"The Virtual International Authority File (VIAF) is an international service designed to provide convenient access to the world's major name authority files. Its creators envision the VIAF as a building block for the Semantic Web to enable switching of the displayed form of names for persons to the preferred language and script of the Web user. VIAF began as a joint project with the Library of Congress (LC), the Deutsche Nationalbibliothek (DNB), the Bibliothèque nationale de France (BNF) and OCLC.

Library of Congress Medium of Performance Thesaurus for Music

"Library of Congress Subject Headings (LCSH) has long included headings that represent the genre or form of musical works in combination with the mediums of performance (e.g., Sonatas (Trombone and organ); Concertos (Bassoon, clarinet, English horn, flute)), as well as headings that represent the mediums of performance alone (e.g., Bass clarinet and piano music). The structure of the headings can sometimes be of marginal utility to researchers, who may be most interested in finding music for a particular combination of instruments and are less focused on the genre of the music.
