- Abstract
- This article presents one part of a wider study, performed at the Department of library and information science and book studies (LIS & BS) at the University of Ljubljana (UL). The study investigated the perceptions of user friendliness of information-retrieval systems (IRS) and the role of individual characteristics of users in these perceptions. Based on an expert study, a user study with 61 postgraduate students of the UL was performed. Three interfaces of e-journals were studied: Science Direct, Proquest Direct, and Ebsco Host. Questionnaires and observations were used for data collection. The users'perceptions of user friendliness and of importance of auxiliary functions were investigated. Also, the connections between these perceptions and the users'individual characteristics were identified. Three sets of individual characteristics were included: approaches to studying, thinking styles, and hemisphere leanings. In connection with the dimensions of individual characteristics, very different perceptions of user friendliness were expressed. Some dimensions of individual characteristics were also found to be connected to the users'academic areas. It is shown that participants from different academic areas have different requirements and perceptions of user friendliness. The results of the study are relevant for the design of the user interfaces of disciplinary IR systems. They also have implications for other areas, for example, user education and training.

- Abstract
- Purpose - The paper aims to present the results of the first two tasks of a user study looking into mental models of the bibliographic universe and especially their comparison to the Functional Requirements for Bibliographic Records (FRBR) conceptual model, which has not yet been user tested. Design/methodology/approach - The paper employes a combination of techniques for eliciting mental models and consisted of three tasks, two of which, card sorting and concept mapping, are presented herein. Its participants were 30 individuals residing in the general area of Ljubljana, Slovenia. Findings - Cumulative results of concept mapping show a strong resemblance to FRBR. Card sorts did not produce conclusive results. In both tasks, participants paid special attention to the original expression, indicating that a special place for it should be considered. Research limitations/implications - The study was performed using a relatively small sample of participants living in a geographically limited space using relatively straight-forward examples. Practical implications - Some solid evidence is provided for adoption of FRBR as the conceptual basis for cataloguing. Originality/value - This is the first widely published user study of FRBR, applying novel methodological approaches in the field of Library and Information Science.

- 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.
