FRBR, FRAD and FRSAD, the three conceptual models developed by IFLA, have influenced the way in which communities around the globe perceive, understand and model the bibliographic universe. The sustained interest in these three conceptual models has led to their continuing evolution. This paper will look at two areas of development: harmonization with other cultural heritage communities to supp...

Subsequently, while maintaining the se...
