This article analyzes bibliographic classification systems for Jewish libraries and Judaica from a cultural perspective, partly detached from their function as document retrieval tools. Theoretically and methodologically, the study refers to the significance of warrants as formulated in Library and Information Science. With specific interest in the relation between Jewish and non-Jewish classification and bibliography, examples are given of systems from Europe and the USA, primarily from the twentieth century. Results indicate that bibliographic classification systems not only represent documents but reproduce cultural and ideological preferences of both designers and historical situations. In their effort to document religion in a bibliographic context, the example systems help to formulate various aspects of Judaism through both hierarchical structuring and subject definition.

Over the last three decades, a number of major changes in the field of cataloging have led to the definition of new forms of authority control. The introduction of FRBR and of IFLA LRM have been followed by continuing studies, including, more recently, the implementation of linked data in library catalogs, as well as improvements to data models in order to ensure the broadest possible interoperability among systems. A new approach to authority control and its connected services can be based on the combination of manual and automatic processes of data validation and enrichment, together with the use of knowledge bases as authoritative sources. This will also grant wider data interoperability, opening up a new level of cooperation among the international institutions and organizations concerned with the dissemination of knowledge.
