Fifty years later, a complete discography with accurate recording-session dates was compiled and made available to the public, following the rediscovery of key company documents.

[1]) The records were lateral needle-cut of the usual kind, starting at the outer edge, and playing at speeds at or near 78 rpm.

It featured a large disc of 35 cm (13 and three-quarter inches); but it ran to only 22 titles before being discontinued as unpopular with the consumer market, owing to the format.

Nonetheless, this fabled relic has become a 'holy grail' of operatic record collectors, who must fall back on the faint and scratchy Mapleson Cylinders, cut during live performances at the New York Metropolitan Opera, in order to hear a dim echo of de Reszke's voice.

It included some operatic titles, though most of the first 100 numbers were dedicated to band music, or to the work of violinists Kubelik and Franz von Vecsey.

It also seems possible that some of the actual recording equipment was transferred to the Odeon studios, for a distinctive feature of the tracking of the groove-cutting equipment in Fonotipia records shows a single revolution halfway through the side where the groove is widely spaced, and this idiosyncrasy (a security feature so that pirate stampers electroplated from a Fonotipia original could be instantly recognised) occasionally persists under Odeon's aegis.

The result was a valuable but slim hardback volume, published in Ipswich, UK, by the Record Collector Shop (at 61 Fore Street).

Among the singers, many of them famous, who recorded for Fonotipia were the following: Aino Ackté, Pasquale Amato, Giuseppe Anselmi, Teresa Arkel, Ernesto Badini, Aristide Baracchi, Maria Barrientos, Ramon Blanchart, Alessandro Bonci, Giuseppe Borgatti, Georgette Bréjean-Silver, Eugenia Burzio, Victor Capoul, Mercedes Capsir, Maria Carena, Margherita Carosio, Ferruccio Corradetti, Emilia Corsi, Armando Crabbé, Gilda Dalla Rizza, Leon David, Nazzareno de Angelis, Elvira de Hidalgo, Giuseppe De Luca, Fernando De Lucia, Emmy Destinn, Adamo Didur, Léon Escalais, Giuseppina Finzi-Magrini, Nicola Fusati, Edoardo Garbin, Giovanni Inghilleri, Maria Jeritza, Jan Kiepura, Solomiya Krushelnytska, Giacomo Lauri-Volpi, Félia Litvinne, Oreste Luppi, Antonio Magini-Coletti, Luigi Manfrini, Gino Martinez-Patti, Victor Maurel, Irene Minghini-Cattaneo, Francesco Navarini, Giuseppe Noto, Giuseppe Pacini, Rosetta Pampanini, Tancredi Pasero, Aureliano Pertile, Lily Pons, Giannina Russ, Mario Sammarco, Emile Scaramberg, Mariano Stabile, Rosina Storchio, Riccardo Stracciari, Conchita Supervia, Richard Tauber, Ninon Vallin, Ernest van Dyck, Francisco Viñas and Giovanni Zenatello.
