    Abstract
    Anhand von 2 alphabetischen Sachregistern der Zeitschrift für Buch- und Druckgeschichte "Het Boek" wird dargestellt, welche Rolle die Klassifikation in Sachregistern spielt bei der Wahl der Erschließungseinheiten und bei der Bestimmung der Indexierungstiefe. Als Hauptfunktion der Klassifikation bei Registern erweist sich jedoch die Erleichterung und Verbesserung des Suchvorganges. Erklärt wird, wie die Methode des ersten Registers, Klassifizierung spezifischer Begriffe unter hierarchisch höhere Begriffe, nicht zum Ziel führt und wie die Kontextmethode einen besseren Zugriff gewährleistet

    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.

    In this paper, after an introduction about problems of multilingual information languages, the rules and recommendations of the Guidelines for the establishment and development of multilingual thesauri for non-equivalence and partial equivalence of terms in different languages are discussed. Artificial terms are not very useful in searching, because most users are not willing to use a thesaurus to find the right descriptor. On the other hand indexers need guidance on how to index and therefore need a thesaurus with all desirable and necessary relations. It is suggested that bibliographic online systems can take over some of the functions for the searcher from the thesaurus and that a few new relations could be helpful to an indexer

    Abstract
    Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved

    Abstract
    There exist in the world many bibliographical databases, which are indexed with the UDC. Searching in the databases is difficult for everyone not very experienced in the use of this classification scheme. The notations can be very complex and often it would be desirable to be able to search on only a part of the notation. In this paper algorithms for the decomposition of complex UDC-notations and adding a description to the resulting simple notations are discussed. In the second part of the paper the resulting texts are discussed

    Abstract
    In this paper the possibilities for a multilingual thesaurus in which not all descriptors in a given language have equivalent descriptors in all other languages and in which the hierarchical structure can have variations in the different languages and a small model of such a thesaurus is given. lt is argued that the searching possibilities that more recent programs for bibliographic databases offer make such non-identical thesauri possible.

    "1. Introduction Multilingual and crosslingual access to information is receiving more and more attention. Maybe the most important reason for this development is the Internet. There are estimations that about half of its users are people with a mother tongue other than English and that this proportion is growing. Crosslingual access in this context means the possibility to get free text access to information using another (natural) language than the language of the information itself. This type of access is important for users with a good passive knowledge of a language but with only a small active vocabulary of the same language, e.g. a Englishman who can read Russian, but has difficulties in formulating adequate search request in that language. Crosslingual access can also be valuable for monolingual users who can automatically or manually have translations of foreign language documents. The search requests will be translated or converted into the language of the information. Multilingual access assumes that the instruments used for access, the controlled information languages, are available in more than one language. An classic example is the Englishman who uses his English edition of the Universal Decimal Classification to search the catalogue of a library in China, although the classification of the library is done using a Chinese edition. In this case the searching and the classifying results in a notation that is the same irrespective which language edition was used for indexing. Another possibility is the use of a multilingual thesaurus or subject headings list, such the trilingual edition of the Library of Congress Subject Headings built at the Royal Library in Brussels (Belgium) or the Macrothesaurus of the OECD. Here, words are the access points - in one language into which each search request will be converted, or, alternatively, into all the languages involved. Multilingual information languages and guidelines an how to build them are the subject of this paper. Particular attention will be paid to multilingual thesauri."

    Abstract
    In the documentation of cartographic materials and geographic information (CM), the accessibility by area or subject plays a major role. In contrast to most library documents, title and author are of minor importance in the retrieval process for CM. Most maps do not mention authors or titles at all. In the new generation of cataloguing rules for CM, an area code followed by a code for subject are defined as the main entry. Concerning CM, the present UDC provisions are so cumbersome that the creation of new auxiliary tables for CM was felt necessary. The proposed new tables consist of an auxiliary table of place, with <...> as the identifying mark, and a table for subjects on CM as a special auxiliary table to the existing general auxiliary (084.3). In this article, the new UDC auxiliary tables for CM are summarized and the underlying problems and considerations are given in context

    Abstract
    In the last decade a discussion has been going an in the Division of Bibliographic Control of the International Federation of Library Associations and Institutions (IFLA) about the principles of cataloguing. This discussion was initiated by the widespread replacement of the card and list catalogues by Online Public Access Catalogues (OPACs) since 1980. In this paper we discuss the role of subject cataloguing in three important documents that are the results of this discussion. Our conclusion is that the interest in subject cataloguing has grown remarkably, but is still not an the level it deserves given the fact that a great part of all searches in OPACs are subject oriented.
    Content
    1. Introduction In this paper we address two questions: 1. What is the position of subject indexing in the thinking of the library world after the publication of the Functional Requirements for Bibliographic Records (1998)? 2. Is this position in accordance with the requirements of the users searching for documents about a given subject? Research Shows that searching an a topic (i.e. subject access) is an important, even predominant type of end-user searching of library catalogues and even more so of other bibliographic databases. Between one third and two thirds of all OPAC searches are probably subject searches (Large & Beheshti, 199%). Taking into account different ways in which searching an a topic is implemented in library catalogues (subject headings, classification, keywords only) the percentage may be even higher. For example title word searching may be a substitute for subject searching if no better tools are available. In the light of this it is not surprising that the Functional Requirements for Bibliographic Records (FRBR) (1998) pays attention to subject searching, as well as the Functional Requirements and Numbering of Authority Records (FRANAR) (2003). Also the Statement of International Cataloguing Principles: Final draft of 19 December 2003, which is the result of the first First IFLA Meeting of Experts an an International Cataloguing Code mentiong subject access as a function of cataloguing (Statement, 2003). In this paper we discuss the ways these three documents deal with subjects.

    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.

    Defines classification. Discusses bibliographic classifications; subject classifications; subjects monitored in classifications; the order of subjects in classifications and the use of classifications. Many library managers question whether controlled subject access is necessary when most searches are done by title words. Where classification is used, the choice of scheme is more often determined by sociological reasoning than by informations cience consideration

    Abstract
    On the 22nd of July, 1989, the International Society for Knowledge Organization (ISKO) was founded. Starting in August 1989 ISKO had an official organ, the journal International Classification. This Journal was founded in 1974 by Dr. Ingetraut Dahlberg, the first President of the ISKO. With volume 20 (1993) the name of the journal was changed to Knowledge Organization. This bibliography has been compiled on the occasion of the second decade of ISKO. This bibliography indexes the content of International Classification and Knowledge Organization starting with International Classification volume 16(1989) issue 3 and ending with Knowledge Organization volume 26(1999) issue 3. All articles and all book reviews are included. From the news items, only those for which an author is mentioned and that were especially written for International Classification or Knowledge Organization, are entered in this bibliography. The bibliography also contains the papers of conferences organized by the International Society for Knowledge Organization, one of its national chapters, or sponsored by the ISKO or one of its chapters. If we overlooked a conference of which the papers should have been included, we apologize for this omission. A list of the conferences included can be found in the list of abbreviations. The bibliography is based on the literature that was available to the compilers. However, not all conference proceedings included in the bibliography could be found in sources available to us. In these cases descriptions from the bibliographies in International Classification and Knowledge Organization were used. For a few proceedings the help of national chapters was sought and obtained. They deserve our thanks. The bibliography is ordered according to the classification used for the current bibliography in Knowledge Organization. The complete classification - as it is used now - is published in this issue of Knowledge Organization. The bibliography also includes an Author Index. We want to add that this bibliography is more complete than the bibliographies in International Classification and Knowledge Organization. We hope that you will find this bibliography useful and timely
