    Abstract
    Aggregates have been a frequent topic of discussion between library science researchers. This study seeks to better understand aggregates through the analysis of a sample of bibliographic records and review of the cataloging treatment of aggregates. The study focuses on determining how common aggregates are in library collections, what types of aggregates exist, how aggregates are described in bibliographic records, and the criteria for identifying aggregates from the information in bibliographic records. A sample of bibliographic records representing textual resources was taken from OCLC's WorldCat database. More than 20 percent of the sampled records represented aggregates and more works were embodied in aggregates than were embodied in single work manifestations. A variety of issues, including cataloging practices and the varying definitions of aggregates, made it difficult to accurately identify and quantify the presence of aggregates using only the information from bibliographic records.

    Paper presented at: IFLA WLIC 2015 - Cape Town, South Africa in Session 207 - Cataloguing. Vgl. den Kommentar von H. Wiesenmüller [Mail vom 25.06.2015]: "hier etwas höchst Spannendes - eine knappe Darstellung des konsolidierten FR-Modells, auf das wir schon so lange warten, und das im kommenden Jahr in das weltweite Begutachtungsverfahren gehen soll: http://library.ifla.org/1084/. Ich muss das Paper selbst auch erst in Ruhe lesen, sehe aber beim schnellen Durchblättern mit Freude bestätigt, dass die Gruppe-3-Entitäten aus FRBR tatsächlich abgeschafft werden. Die FRSAD-Entität "Thema" (die für alles stehen kann, was Thema eins Werks ist) wird umgetauft in "Res" (von lateinisch "res", Sache) und steht für "any entity in the universe of discourse". Die Entitäten der Gruppe 2 heißen jetzt zusammenfassend "Agent" und teilen sich auf in "Person" und "Group", wobei letzteres Körperschaften und Familien umfasst. Neu eingeführt wird "Time-span". Auf den ersten Blick scheint das jedenfalls alles ganz gut durchdacht zu sein."

    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
    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
    In 1998, the FRBR model (Functional Requirements for Bibliographic Records) was developed under the auspices of the International Federation of Library Associations and Institutions (IFLA). The library domain finally developed its conceptual model of the bibliographic universe and thus the basis for the development of novel bibliographic information systems. In 2017, the IFLA Library Reference Model (Riva, LeBoeuf and Zumer 2017) was formally accepted as an IFLA standard. The FRBR family of models as well as LRM all start from the user tasks that need to be enabled and supported by bibliographic information systems. The consolidation process included a detailed analysis of all entities, attributes and relationships defined by the FRBR family. In this paper, the main features of the model are presented and described. With IFLA LRM, we finally have a modern model, compatible with the semantic web.

    Abstract
    FRBR, FRAD, and FRSAD models propose user tasks as a way to address and categorize functions that a catalog should support. The user tasks are not harmonized among these models, but to do that, they should first be fully understood and analyzed, especially "select" and "identify." We decided to look at the FRBR user tasks from the perspective of interactive information retrieval (IIR). Several IIR models were reviewed and Ellis' and Belkin's models were chosen for further analysis and interpretation of FRBR "select" and "identify" tasks.

    Abstract
    Functional Requirements for Bibliographic Records (FRBR, 1998), the study commissioned by IFLA, brings revolutionary changes in the way we see modern computer catalogues. The catalogue is not seen as a sequence of bibliographic records and a copy of a card catalogue, but as an interconnected network of related information. Implications of the new model for the future development of catalogues are discussed. Special attention is given to access points and relationships between entities and the changes those will bring into both the formal and subject cataloguing, and authority files.

    Abstract
    The study Functional Requirements for Bibliograpbic Records (FRBR) was commissioned by IFLA and published in 1998. It defines the core functions of a catalogue (and bibliographic records) as a gateway to information. For that purpose an abstract entity-relationship model of a catalogue is proposed. The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected entities, enabling the user to perform seamlessly all the necessary functions. So far there has been some theoretical discussion of the model and some limited experiments, but there is a lack of research in how to implement this theoretical model in practice, in new-generation catalogues. In this paper some reactions to the model are analysed. The main focus is an consequences of the model for the OPAC interface design, particularly the searching functionality and display of results.

    Abstract
    In the bibliographic environment, the term aggregate is used to describe a bibliographic entity formed by combining distinct bibliographic units together. Aggregates are a large and growing class of information resources-up to twenty percent of the bibliographic records in OCLC's WorldCat may represent aggregates. The Functional Requirements for Bibliographic Records: Final Report only briefly references aggregates. Difficulties and inconsistencies in the application of the FRBR model to aggregates have been identified as a significant impediment to FRBR implementation. To address the issue, the FRBR Review Group established a Working Group on Aggregates which completed its charge and submitted its final report in 2011. The Working Group proposed that an aggregate be defined as a "manifestation embodying multiple distinct expressions". This paper examines the proposed definition and explores how aggregates can be modeled.

    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.
