Since the Seventies in Faenza, dedicated to social and cultural engagement and biblio- graphic heritage events, like library exhibitions and children’s book fairs, to the Pisan and Bologna season, started in 1987 and focused on academic research and on teaching. Tavoni arranged in her lifetime the fate of her own and other people’s libraries, saved from dispersion and intended to be- come bibliographic collections open to the public.
