    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
    Purpose - The paper aims to provide some insight into mental models of the bibliographic universe and how they compare with functional requirements for bibliographic records (FRBR) as a conceptual model of the bibliographic universe. Design/methodology/approach - To get a more complete picture of the mental models, different elicitation techniques were used. The three tasks of the paper were: card-sorting, concept mapping and comparison task. The paper deals with comparison task, which consisted of interviews and rankings, and provides a discussion of the results of the paper as a whole. Findings - Results of the ranking part of the comparison task confirm the findings of concept mapping task. In both cases, while there are individual differences between mental models, on average they gravitate towards FRBR. Research limitations/implications - This is a small study and it provides only a glimpse of the implications of using FRBR as a conceptual basis for cataloguing. More FRBR-related user studies are needed, including similar studies on different groups of individuals and different types of materials, as well as practical studies of user needs and user interfaces. Practical implications - The results of this study are the first user-tested indication of the validity of FRBR as a conceptual basis for the future of cataloguing. Originality/value - This is the first published paper of mental models of the bibliographic universe and uses a unique combination of mental model elicitation techniques.

    Abstract
    Purpose - This paper aims to build on of a previous study of mental models of the bibliographic universe, which found that the Functional Requirements for Bibliographic Records (FRBR) conceptual model is intuitive. Design/methodology/approach - A total of 120 participants were presented with a list of bibliographic entities and six graphs each. They were asked to choose the graph they thought best represented the relationships between entities described. Findings - The graph based on the FRBR model was chosen by more than half of the participants and none of the alternatives stood out. This gives further indication that FRBR is an appropriate model of the bibliographic universe from users' standpoint. Research limitations/implications - The study only looked at the textual part of the bibliographic universe. Further research is needed for other types of materials. Practical implications - This research suggests that there should be a more positive attitude towards implementation of FRBR-based catalogues. Originality/value - This is one of only a handful of user studies relating to FRBR, which looks to be the backbone of catalogues for years to come. As such, the results should be of interest to everybody involved with catalogues, from cataloguers to the end-users.

    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
    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.
