CATALOGUE OF MUSIC

The catalogue of Music is in two sections, section 1 consisting of a catalogue of musical compositions entered under the names of composers, with cross- references from arrangers or editors ; section 2, of cross-references from the authors of words set to music to the names of the composers in section 1. The arrangement of both sections of the catalogue is alphabetical. In section 1 cross-references are also made : (1) in the case of vocal music, from the first word of the name of the song ; (2) in the case of operas, oratorios, and other choral works, from their full title to the names of the composers.

Anonymous compositions : (1) if instrumental, are to be catalogued under the first substantive of the title, or, if there be no title, under the name of the kind of music of which they consist ; (2) if vocal, under the first word of the first line, with a cross-reference from the name of the composer, if ascertainable.

Collections of psalms or hymns are entered under the name of the editor or collector, with a cross-reference from either heading ; if anonymous, even though they possess a title, under the class- heading Psalms or Hymns.
