ABSTRACT
The Functional Requirements for Bibliographic Records (FRBR) model has been the main framework of reference for the new Italian cataloging rules. The code puts the work at the center of the catalog and of the rules because users are mostly interested in works and the most wanted works are increasingly available in multiple manifestations. Every work should be identified in the catalog and responsibility relations should be recorded at the proper level. The code is tailored to the specific needs of library cataloging and based on a new thorough analysis of the phenomena to be reflected, organized, and made accessible via the catalog.
