The OVI has entered into an agreement with Edizioni ETS Srl of Pisa, Salerno Editrice Srl of Rome and SISMEL - Edizioni del Galluzzo of Florence for the provision of PDF files of critical editions of Italian texts published under their imprint, which are intended to implement the OVI corpora, as well as complimentary copies of their volumes. The collaborations are added to the now historical one with the Edizioni Dell’Orso of Alessandria, which since 1999 has edited the Bollettino and other publications of the OVI Institute.
