In this section there are some loose editions or monographic publications tied to periodicals edited by Ricordi, or which refer to the history of the music publishing house.

In the first group are both the Biblioteca Illustrata della Gazzetta Musicale di Milano (An Illustrated Library of the Gazette of the Music of Milan) and the Supplementi straordinari (Special Supplements), such as those printed for the deaths of Rossini and Verdi, or those dedicated to particular topics, such as the Teatri di Pompei (Theaters of Pompei). The formats vary, and they are adapted to the formats of the Gazzetta at the time of their publication. The single supplements can be found both bound together with the year to which they belong, or separately. To this can be added n.1 of the Quaderni di Musica d’oggi (Notebooks of Today’s Music) dedicated to the theme of Scuola-Musica (School-Music), which gathers all the articles appearing in Musica d’Oggi between October 1959 and December 1960 about teaching music in European and American elementary schools and high schools.

Various editions appear in the second group. There is a special issue published in 1908 of Il Risorgimento Grafico, a magazine of the graphic arts and typography, which was dedicated to the centenary of the Ricordi publishing house, and which also included previously unpublished photographs. Similarly, there is also Profili Biografici, promoted in 1911 by the Commissione Festeggiamenti dell’Unione Industriali arti grafiche ed affini (The Celebrations Committee of the Industrial Union for Graphic Arts and Related Fields) to honor the 10 people still active after 50 years, including Rusconi, Treves, and Giulio Ricordi. In addition, there are special publications, such as Il Nerone alla Scala, which are part of the section of individual editions dedicated to extraordinary theater events, such as the previous ones for Otello and Falstaff edited by the Fratelli Treves. It was 1924, and the posthumous presentation of Arrigo Boito’s opera Nerone, directed by Toscanini, was considered the event of the year. Another carefully produced publication rich with illustrations was dedicated, instead, to the Wagnerian Il crepuscolo degli dei, 1913, edited by Carlo Clausetti of the Ricordi office in Naples of which he was then director and later co-manager.
