The IRIS Consortium is able to accommodate in its union catalogue RDA records derived from two authoritative sources, The Library of Congress and the Berenson Library (The Harvard University Center for Italian Renaissance Studies). The consortium's position at this time, however, is to integrate into our original cataloguing some of the most useful aspects of RDA without taking the full ‘plunge’ into RDA (toolkit subscription, retraining, etc.). In Italy we may very well be, for varying reasons, in a not uncommon situation.
