ABSTRACT
Catalogues of music are usually kept apart from the general catalogue and, consequently, are issued as separate class-lists. As a rule these lists comprise not only the musical scores but also the books on musical subjects, such as the theory and history of music and musical instruments, biographies of musicians, critical works, and the like. In general terms it may be stated that the composer of the music is invariably regarded as the author for all entries, and the writers of librettos of operas, or of the words of songs, take a secondary place. If the catalogue of music is the usual separate class-list an index of composers might be superfluous, though one of the titles of operas, songs, and pieces might prove of some small service. If music is introduced into the dictionary catalogue the main-entry is given, as already stated, under the composer’s name, with such references from the librettist or arranger as may be considered desirable.
