Work Records in WorldCat


View rich descriptions for books and other library materials.

This project applies principles of the FRBR model to aggregate bibliographic information above the manifestation level. Records are clustered into works using the OCLC FRBR Work-Set Algorithm. The algorithm collects bibliographic records into groups based on author and title information from bibliographic and authority records. Author names and titles are normalized to construct a key. All records with the same key are grouped together in a work set.

Data elements from records within a given work set are aggregated at the work level to form descriptions that are richer and more complete than the descriptions in individual bibliographic records. Work level records can provide the foundation for new information systems and services.


FRBR (Functional Requirements for Bibliographic Records) is a conceptual reference model developed by the International Federation of Library Associations and Institutions (IFLA). The model provides "a reference point for testing the validity and robustness of extant data models and data structures. It can therefore be used to improve extant formats as well as to provide guidance for the process of developing new formats" (FRBR – Frequently Asked Questions).

This project is one of six OCLC Research projects that address organizing bibliographic data according to the FRBR data model. More information about FRBR and related OCLC Research projects is available on the main FRBR activity page.
