Parsifal is the fruit of a long collaborative journey that began in 1973 and consolidated in 1991 with the signing of the founding act of the URBE Association. The milestone of Parsifal honours to those in charge of URBE – first and foremost, the rectors of the pontifical institutions – for having believed in the proposal for bibliographic cooperation. The protagonist of this story has been the cataloguers of the now involved twenty libraries, the Governing Council, and the Share Family initiative. Designed in compliance with BIBFRAME, ensuring the compatibility with IFLA LRM and in line with RDA guidelines Parsifal fosters the dialogue to transcend national, linguistic cultural and domain boundaries.
