Functional Requirements for Bibliographic Records (FRBR)

Developed by the International Federation of Library Associations (IFLA).

The Functional Requirements for Bibliographic Records (FRBR) is a conceptual model that is meant to describe the different entities that compose the bibliographic universe and their inter-relationships, connecting the model to user tasks FRBR-based systems support. The most commonly known features of the FRBR model is its four user tasks (Find, Identify, Select, and Obtain) and the Group 1 Entities which categorize the products of intellectual and artistic endeavors (Work, Expression, Manifestation, and Item). Other entities included in the model are the Group 2 Entities representing creators (Person and Corporate Body), and Group 3 Entities which are the subjects of Works (Group 1 Entities, Group 2 Entities, plus Concept, Object, Event, and Place). The FRBR model, together with the Functional Requirements for Authority Data (FRAD), serves as the foundation of Resource Description and Access (RDA).
