Abstract

The IFLA study Functional requirements for bibliographic records (FRBR) set a new frame for both cataloguing codes and subject analysis. The Paris Principles defined the functions of the catalogue followed by both cataloguing codes used in Slovenia: P. Kalan's Abecedni imenski katalog and E. Verona's Pravilnik i prirunik za izradbe abecednih kataloga. FRBR defines the functions for records themselves, irrespective of the type of the database consisting of these records. Compared to the requirements for the national bibliographic records as defined by FRBR, the records belonging to the Slovenian national bibliography show more descriptive elements and less notes on bibliographic history, which reflects in lack of uniform titles. As the uniform title itself enables the identification of related works and their expressions, this practice does not satisfy the FRBR requirements. Differences in the extent of records for different types of material derive from decentralised processing at the National and University Library. It is therefore necessary to establish uniform criteria for both the materials included into the Slovenian national bibliography, and the extent of data elements.

Abstract

Purpose - Bibliographic records should now be used in innovative end-user applications that enable users to learn about, discover and exploit available content, and this information should be interpreted and reused also beyond the library domain. New conceptual models such as FRBR offer the foundation for such developments. The main motivation for this research is to contribute to the adoption of the FRBR model in future bibliographic standards and systems, by analysing limitations in existing bibliographic information and looking for short- and long-term solutions that can improve the data quality in terms of expressing the FRBR model. Design/methodology/approach - MARC records in three collections (BIBSYS catalogue, Slovenian National Bibliography and BTJ catalogue) were first analysed by looking at statistics of field and subfield usage to determine common patterns that express FRBR. Based on this, different rules for interpreting the information were developed. Finally typical problems/errors found in MARC records were analysed. Findings - Different types of FRBR entity-relationship structures that typically can be found in bibliographic records are identified. Problems related to interpreting these from bibliographic records are analyzed. Frbrisation of consistent and complete MARC records is relatively successful, particularly if all entities are systematically described and relationships among them are clearly indicated. Research limitations/implications - Advanced matching was not used for clustering of identical entities. Practical implications - Cataloguing guidelines are proposed to enable better frbrisation of MARC records in the interim period, before new formats are developed and implemented. Originality/value - This is the first in depth analysis of manifestations embodying several expressions and of works and agents as subjects.

Abstract

Purpose - Despite the importance of bibliographic information systems for discovering and exploring library resources, some of the core functionality that should be provided to support users in their information seeking process is still missing. Investigating these issues, the purpose of this paper is to design a solution that would fulfil the missing objectives. Design/methodology/approach - Building on the concepts of a work family, functional requirements for bibliographic records (FRBR) and information visualization, the paper proposes a model and user interface design that could support a more efficient and user-friendly presentation and navigation in bibliographic information systems. Findings - The proposed design brings together all versions of a work, related works, and other works by and about the author and shows how the model was implemented into a FrbrVis prototype system using hierarchical visualization layout. Research limitations/implications - Although issues related to discovery and exploration apply to various material types, the research first focused on works of fiction and was also limited by the selected sample of records. Practical implications - The model for presenting and interacting with FRBR-based data can serve as a good starting point for future developments and implementations. Originality/value - With FRBR concepts being gradually integrated into cataloguing rules, formats, and various bibliographic services, one of the important questions that has not really been investigated and studied is how the new type of data would be presented to users in a way that would exploit the true potential of the changes.

Abstract

Since their beginnings, bibliographic information systems have been displaying results in the form of long, textual lists. With the development of new data models and computer technologies, the need for new approaches to present and interact with bibliographic data has slowly been maturing. To investigate how this could be accomplished, a prototype system, FrbrVis1, was designed to present work families within a bibliographic information system using information visualization. This paper reports on two user studies, a controlled and an observational experiment, that have been carried out to assess the Functional Requirements for Bibliographic Records (FRBR)-based against an existing system as well as to test four different hierarchical visual layouts. The results clearly show that FrbrVis offers better performance and user experience compared to the baseline system. The differences between the four hierarchical visualizations (Indented tree, Radial tree, Circlepack, and Sunburst) were, on the other hand, not as pronounced, but the Indented tree and Sunburst design proved to be the most successful, both in performance as well as user perception. The paper therefore not only evaluates the application of a visual presentation of bibliographic work families, but also provides valuable results regarding the performance and user acceptance of individual hierarchical visualization techniques.

Abstract

The aim of this article is to analyze how catalogers describe publications without cataloging tools in comparison with the current cataloging process. A total of 46 catalogers took part in the first study, a free description of monographic publications, while 30 catalogers performed original cataloging in their actual environment. A combination of observations and think-aloud protocols was used for data gathering in both studies. The focus was on Slovenian catalogers from different types and sizes of libraries. Results revealed both differences and similarities between catalogers' mental models in the respective studies.

Abstract

The aim of this paper is to present a prototype cataloging interface, which provides easier data entry, follows the cataloger's thought process and is based on the advantages of the IFLA LRM model. The paper summarizes all stages of the conceptual design and shows how the LRM was implemented. The main purpose of the cataloging interface design is to show how a LRM-based cataloging module might look like and how it could improve the existing cataloging process.

Abstract

The FR family of conceptual models has grown to include three separate models prepared independently over many years by different working groups: FRBR for bibliographic data, FRAD for authority data, and FRSAD for subject authority data. Even as FRAD and FRSAD were being finalized in 2009-2010, it became clear that it would be necessary to combine or consolidate the FR family into a single coherent model to clarify the understanding of the overall model and remove barriers to its adoption. The FRBR Review Group has been working towards this since 2011, constituting a Consolidation Editorial Group in 2013. The consolidation task involves not only spelling out how the three existing models fit together, but requires taking a fresh look at the models to incorporate insights gained since their initial publications. This paper, based directly on the work of the Consolidation Editorial Group, provides the first public report of the consolidated model, tentatively referred to as the FRBR-Library Reference Model (FRBR-LRM), and the guiding principles that have been applied in its development.
