The Functional Requirements for Bibliographic Records (FRBR) is a conceptual model designed to improve the organization and retrieval of bibliographic information. It categorizes information into four main entities: Work, Expression, Manifestation, and Item. This structure helps libraries and information systems better understand and manage the relationships between different forms of a publication. FRBR emphasizes the importance of user needs in accessing information. By distinguishing between the creative aspects of a Work and its physical representation as a Manifestation, it allows users to find the specific version or format they are looking for, enhancing the overall search experience in library catalogs and databases.
