The critical edition of the complete works of Giuseppe Verdi is a joint publication of the University of Chicago Press and Casa Ricordi in Milan, which aims to make available to scholars, students, and performers, reliable editions of Verdi's music that are both faithful to the sources and suitable for performance. The works included in the project are at the core of the nineteenth-century operatic repertory, from Rigoletto, Trovatore, and La traviata, to Un ballo in maschera, Otello and Falstaff.
