    Abstract
    From a logical point of view, an OPAC is an inventory with indexes. Inventories can be accumulated and the indexes merged. However, in most merged catalogues not all documents have the same subject indexing and a number of documents are indexed by more than one system. In practice, a merged catalogue also contains descriptions without subject indexing. To augment the situation four methods are used: searching with title keywords, mapping and switching, acceptance of descriptions indexed in a given way only, and »citation pearl growing«. The last method uses all available subject indicators by using subject indicators present in relevant descriptions found by already known indicators. This method can also be of help in mapping and switching.

    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
    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.
