“L'epistolario di Ugo Foscolo: catalogo” is the outcome of the doctoral sub-project of the research project "Ugo Foscolo, Epistolario 1825-1827" (https://data.snf.ch/grants/grant/197859). The catalogue describes all the known letters of the Italian-Greek poet's epistolary in relation to manuscripts and copies, the subjects that conserve them, editions, people and places: the aim of the work is to offer a catalogue that provides access to all known information on a letter, a character, a particular manuscript in relation to the Foscolo tradition.
