OCLC FRBR Work-Set Algorithm
A work set is a group of bibliographic records that has the same Author/Title key
A key is generated for each bibliographic record
Variant forms of names and titles are converted to established forms based on information in the OCLC authority file
Keys are sorted and compared to form work sets

Buizza and Guerrini on Subjects (1)
“The subject belongs to the real world as a conceptual representation of the indexer, which represents the contents of the work in a summarized and formalised way.”
Buizza, Pino, and Mauro Guerrini. "A Conceptual Model for the NewSoggettario: Subject Indexing in the Light of FRBR." Cataloging &Classification Quarterly 34 (2002): 31-45.<http://www.haworthpressinc.com/>.
“The subject is not an entity present in the work and extracted from it, nor is it a preconstructed entity which exists in its own right. It exists as a conceptual nucleus of information created in order to mediate between the theme developed in the work and the universe of cultural and informational discourses which originate the requests for bibliographical enquiries.”
Buizza and Guerrini on Subjects (2)
What work has the following as subjects?
Adventure and adventurers Animals Curiosity Decision making Dreams Fantasy Girls Illusion (Philosophy) Imagination Innocence (Psychology) Rabbits
Alice’s adventures in wonderland
Adventure and adventurers Animals Curiosity Decision making Dreams Fantasy Girls Illusion (Philosophy) Imagination Innocence (Psychology) Rabbits
“It is a logical entity which persists through the various relationships with diverse works, independent of the expressions and manifestations in which they occur, and allows us to recognise and relate the works which present the same basic theme and to distinguish them from those which develop different themes.”
