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
