"The object of the compiler of this Handbook is to present to the reader a brief but comprehensive sketch of each of the operas contained in the modern repertory which are likely to be given during regular seasons. To this end he has consulted the best authorities, adding to the material thus collected his own observations, and in each case presented a necessarily brief sketch of the composer, the story of each opera, the general character of the music, its prominent scenes and numbers, -the latter in the text most familiar to opera-goers, -the date of first performances, with a statement of the original cast wherever it has been possible to obtain it, and such historical information concerning the opera and its composition as will be of interest to the reader."
