Abstract

A major problem for bibliographic retrieval is an absence of explicit linkages to guide users among manifestations of a work. The purpose of this research was to enhance the power of bibliographic retrieval systems by providing contextual information about the derivative bibliographic relationship. Descriptive survey method was employed. A sample of 411 works from the Georgetown University on-line catalog was drawn. 49.9% of works were derivative. Age of a progenitor work is the characteristic most strongly associated with derivation; language and country of origin are indifferent predictors. Popularity of works might contribute to the phenomenon of derivation. The mean size of bibliographic families of derivative works was 8.44 members. The majority of bibliographic families had successive derivations, large groups of bibliographic families had translations and simultaneous editions; few had extractions, amplifications, or performances; none had adaptations. Successive derivations are the most commonly found members of bibliographic families, and are associated with most other types of derivation within bibliographic families. The bibliographic data required for explicit control of works might easily be compiled from existing records. The development of bibliographic retrieval systems in the network environment could play a dramatic role in improving retrieval of works

Abstract

A work is a deliberately created informing entity intended for communication. A work consists of abstract intellectual content that is distinct from any object that is its carrier. In library and information science, the importance of the work lies squarely with the problem of information retrieval. Works are mentefacts-intellectual (or mental) constructs that serve as artifacts of the cultures in which they arise. The meaning of a work is abstract at every level, from its creator's conception of it, to its reception and inherence by its consumers. Works are a kind of informing object and are subject to the phenomenon of instantiation, or realization over time. Research has indicated a base typology of instantiation. The problem for information retrieval is to simultaneously collocate and disambiguate large sets of instantiations. Cataloging and bibliographc tradition stipulate an alphabetico-classed arrangement of works based on an authorship principle. FRBR provided an entity-relationship schema for enhanced control of works in future catalogs, which has been incorporated into RDA. FRBRoo provides an empirically more precise model of work entities as informing objects and a schema for their representation in knowledge organization systems.
