【方法】「Resource Description and Access (RDA)」,「日本目録規則1987年版(NCR1987)」,「日本目録規則2018年版案(NCR2018)」を分析対象とした。具体的には,①各記述規則の「著作」の用語定義を確認した上で,「著作」の同一性の操作的定義の視点から,②同一「著作」集合の形成および③「著作」間の境界線に焦点を当て,3つの記述規則の規定を比較分析した。最後に,それらの結果をまとめ各記述規則の「著作」の特徴を整理するとともに,「著作」の同一性の操作的定義について課題と改善策を考察した。


Purpose: To improve the function of library catalogs, the concept of “Work” and navigation functions based on the concept of Work are both essential. However, its definition often varies depending on individual catalogers, resulting in unstable interpretations. Subsequently, the concept of Work is found to be difficult to use for the creation of bibliographic records. To handle the abstract concept of Work in a practical context, it is necessary to provide an operational definition on its identity. The purpose of this study is to examine the characteristics of Work in descriptive rules in terms of operational definitions on its identity.

Methods: In this study, three descriptive rules were examined: Resource Description and Access (RDA), Nippon Cataloging Rules, 1987 Edition, 3rd Revised Edition (NCR1987) and Nippon Cataloging Rules, 2018 Edition draft (NCR2018). They were examined and analyzed from the viewpoints of: (1) the definitions of Work within the rules, (2) the collocating function of Works, and (3) the criteria for determining the boundaries between one Work and another. Finally, an improvement plan is discussed.

Results: The definition of Work in NCR1987 is different from the definition in FRBR and it is not a fully operable entity. In contrast, NCR2018 and RDA include sufficient rules, which can easily lead to Work collocation, and those rules link the definition of Work based on FRBR and its operational definition on identity. While the boundaries of Work are fixed in NCR2018 and RDA, there remain cases where the boundaries vary depending on individual catalogers’ judgment for identifying Works.
