Catalogers, catalog managers, and others in library technical services have become increasingly interested in, worried over, and excited about FRBR (the acronym for Functional Requirements of Bibliographic Records). Staff outside of the management of the library's bibliographic database may wonder what the fuss is about (FERBER? FURBUR?), assuming that FRBR is just another addition to the stable of acronyms that catalogers bandy about, a mate or sibling to MARC and AACR2. FRBR, however, has the potential to inspire dramatic changes in library catalogs, and those changes will greatly impact how reference and resource sharing staff and patrons use this core tool. FRBR is a conceptual model for how bibliographic databases might be structured, considering what functions bibliographic records should fulfill in an era when card catalogs are databases with unique possibilities. In some ways FRBR clarifies certain cataloging practices that librarians have been using for over 160 years, since Sir Anthony Panizzi, Keeper of the Printed Books at the British Museum, introduced a set of 91 rules to catalog the print collections of the museum. This article briefly describes FRBR and how to apply it.
