Center's (OCLC) WorldCat. The goal of the study is to gauge the characteristics of bibliographic entities under study, to examine types of relationships these entities exhibit, and to collocate bibliographic entities according to the FRBR group 1 hierarchy of entities identified as works, expressions, manifestations, and items. The study's findings show that by assembling bibliographic records into interrelated clusters and displaying these according to the FRBR entity-relationship model, a new navigational capability in networked digital libraries can be developed.
