The research button for bibliographical research leads to the “Bibliografia Verdiana” published yearly in “Studi Verdiani”, the musicological Year Book produced by the National Institute for Verdi Studies. At the time of writing it is possible to consult documents from 1982 onwards (the first publication in the series) up until 2014, including the Bibliography for Verdi begun in 1977. The full catalogue of these publications, essays and magazines and publications held in the Institute’s library can be consulted on www.sbn.it and www.unipr.it. The bibliographical research has been undertaken, over the years, by scholars and collaborators from the National Institute of Verdi Studies: Marcello Conati, Michela Crovi, Fabrizio Della Seta, Marisa Di Gregorio Casati and Marco Marica.
