The John Milton and Ruth Neils Ward Collection of the Harvard Theatre Collection is comprised of thousands of books, scores, librettos, playbills, illustrations, and ephemera relating to public performances that incorporate music in an essential way, such as ballet, opera, social dance, pantomime, operetta, and burlesque. With over 1,400 entries and 33 illustrations, this volume provides a window into the historical significance of the King's Theatre to the cultural life of London and abroad, and will appeal to musicologists, historians, theater scholars, and librarians interested in eighteenth- and nineteenth-century opera and ballet.
