    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.

    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
    Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.

    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
    Integrating resources are distinct in that they change over time in such a way that their previous content is replaced with updated content. This study examines how integrating resources can be modeled using the entities and relationships of the IFLA Library Reference Model (LRM) and clarifies how they can be identified. While monographs have been extensively analyzed, integrating resources have received very little attention. Applying the model unmodified to integrating resources is neither practical nor theoretically sound. With the addition of two proposed relationships, the model can be extended to accommodate the diachronic relationship intrinsic between expressions and manifestations exhibited by integrating resources.

    Abstract
    Scientific enterprise represents a pivotal area in knowledge organization because of its prolific use of emerging information technology and its close network of researchers in government, industry, and universities as producers and consumers of knowledge. The ALCOM/NIST Heterogeneous Structures Database (http://cpip.kent.edu/PSP) is an online information system involving university research scientists, government agencies, and industrial partners in the ALCOM/NIST Heterogeneous Structures Project. The Database is the first stage of a multiphase knowledge base of liquid crystal science, the Basic and Applied Liquid Crystal Research Database. This paper will describe the system functionality of the Heterogeneous Structures Database and the expansion of a previously existing tool, the Thesaurus for Liquid Crystal Research and Applications (http://www.personal.kent.edu/~slis/zeng/maja2.html), into the Database. The first part of the paper will discuss how the design of the Database addresses the following user characteristics from multidisciplines involved in the project: interdisciplinarity, basic and applied research, experts and novices users, and user population groups (academia, government, and industry). The second part of the paper will report on how the authors are developing a frame of knowledge structure to meet these characteristics

    Metadata related to cultural items such as literature, music and movies is a valuable resource that is currently exploited in many applications and services based on semantic web technologies. A vast amount of such information has been created by memory institutions in the last decades using different standard or ad hoc schemas, and a main challenge is to make this legacy data accessible as reusable semantic data. On one hand, this is a syntactic problem that can be solved by transforming to formats that are compatible with the tools and services used for semantic aware services. On the other hand, this is a semantic problem. Simply transforming from one format to another does not automatically enable semantic interoperability and legacy data often needs to be reinterpreted as well as transformed. The conceptual model in the Functional Requirements for Bibliographic Records, initially developed as a conceptual framework for library standards and systems, is a major step towards a shared semantic model of the products of artistic and intellectual endeavor of mankind. The model is generally accepted as sufficiently generic to serve as a conceptual framework for a broad range of cultural heritage metadata. Unfortunately, the existing large body of legacy data makes a transition to this model difficult. For instance, most bibliographic data is still only available in various MARC-based formats which is hard to render into reusable and meaningful semantic data. Making legacy bibliographic data accessible as semantic data is a complex problem that includes interpreting and transforming the information. In this article, we present our work on transforming and enhancing legacy bibliographic information into a representation where the structure and semantics of the FRBR model is explicit.

    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
    This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

    Abstract
    The Working group on Guidelines for (electronic) national bibliographies was established in 2004 has started the work with an analysis of users and contexts of use of national bibliographies (NB) in the digital age. National bibliographies are changing dramatically: they include more and more also bibliographic records for digital resources and national bibliographic agencies are increasingly complementing (or even replacing) printed versions of NB with electronic. The guidelines will be soon posted for the world-wide review; this paper gives and overview of the document prepared so far.

    Abstract
    The paper presents the approach of using the Functional Requirements for Bibliographic Records (FRBR) model to investigate the complicated sets of relationships among different versions of a classification system for the purposes of specifying provenance of classification data and facilitating collaborative efforts for using and reusing classification data, particularly in a linked data setting. The long-term goal of this research goes beyond the Dewey Decimal Classification that is used as a case. It addresses the questions of if and how the modelling approach and the FRBR-based model itself can be generalized and applied to other classification systems, multilingual and multicultural vocabularies, and even non-KOS resources that share similar characteristics.

    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.
