The report from the IFLA Study Group on the Functional Requirements for Bibliographic Records (FRBR) recommended a new approach to cataloging based on an entity-relationship model. This study examined a single work, The Expedition of Humphry Clinker, to determine benefits and drawbacks associated with creating such an entity-relationship model. Humphry Clinker was selected for several reasons-it has been previously studied, it is widely held, and it is a work of mid-level complexity. In addition to analyzing the bibliographic records, many books were examined to ensure the accuracy of the resulting FRBR model. While it was possible to identify works and manifestations, identifying expressions was problematic. Reliable identification of expressions frequently necessitated the examination of the books themselves. Enhanced manifestation records where the roles of editors, illustrators, translators, and other contributors are explicitly identified may be a viable alternative to expressions. For Humphry Clinker, the enhanced record approach avoids the problem of identifying expressions while providing similar functionality. With the enhanced manifestation record, the three remaining entity-relationship structures-works, manifestations, and items-the FRBR model provides a powerful means to improve bibliographic organization and navigation.
