FRBR = Functional Requirements for Bibliographic Records

Developed by cataloging experts working under the auspices of IFLA (International Federation of Library Associations and Institutions)

FRBR is from a document issued by IFLA:

• Functional requirements for bibliographic records : final report (1998)

FRBR is a conceptual model not a standard

• FRBR systematically models the bibliographic universe

OCLC FRBR Work-set AlgorithmOCLC FRBR Work-set Algorithm

Provides a FRBR-based view of the data

1.Records clustered into works using author and title fields from bibliographic and authority records

2. Author names and titles normalized to construct a work key

3. All records with the same key are grouped together in a work set or cluster
