    Abstract
    Bradfordrsquos law of scattering is said to be about subject scattering in information sources. However, in spite of a corpus of writings about the meaning of the word ldquosubjectrdquo and equivalent terms such as ldquoaboutnessrdquo or ldquotopicalityrdquo, the meaning of ldquosubjectrdquo has never been explicitly addressed in relation to Bradfordrsquos law. This paper introduces a distinction between Lexical scattering, Semantic scattering, and Subject scattering. Neither Bradford himself nor any follower has explicitly considered the differences between these three and the implications for the practical applications of Bradfordrsquos law. Traditionally, Bradfordrsquos law has been seen as a neutral and objective tool for the selection of the most central information sources in a field. However, it is hard to find actual reports that describe how Bradfordrsquos law has been applied in practical library and information services. Theoretical as well as historical evidence suggest that the selection of journals based on Bradford-distributions tend to favorite dominant theories and views while suppressing views other than the mainstream at a given time.

    Abstract
    The term 'the bibliographic paradigm' is used in the literature of library and information science, but is a very seldom term and is almost always negatively described. This paper reconsiders this concept. Method. The method is mainly 'analytical'. Empirical data concerning the current state of the UDC-classification system are also presented in order to illuminate the connection between theory and practice. Analysis. The bibliographic paradigm is understood as a perspective in library and information science focusing on documents and information resources, their description, organization, mediation and use. This perspective is examined as one among other metatheories of library and information science and its philosophical assumptions and implications are outlined. Results. The neglect and misunderstanding of 'the bibliographic paradigm' as well as the quality of the new UDC-classification indicate that both the metatheoretical discourses on library and information science and its concrete practice seem to be in a state of crisis.

    Abstract
    This article presents a socio-cognitive perspective in relation to information science (IS) and information retrieval (IR). The differences between traditional cognitive views and the socio-cognitive or domain-analytic view are outlined. It is claimed that, given elementary skills in computer-based retrieval, people are basically interacting with representations of subject literatures in IR. The kind of knowledge needed to interact with representations of subject literatures is discussed. It is shown how different approaches or "paradigms" in the represented literature imply different information needs and relevance criteria (which users typically cannot express very well, which is why IS cannot primarily rely on user studies). These principles are exemplified by comparing behaviorism, cognitivism, psychoanalysis, and neuroscience as approaches in psychology. The relevance criteria implicit in each position are outlined, and empirical data are provided to prove the theoretical claims. It is further shown that the most general level of relevance criteria is implied by epistemological theories. The article concludes that the fundamental problems of IS and IR are based in epistemology, which therefore becomes the most important allied field for IS.

    Abstract
    The basic realist claim is that a mind-independent reality exists. It should be common sense knowledge to accept this claim, just as any theories that try to deny it soon become inconsistent because reality strikes back. In spite of this, antirealist philosophies flourish, not only in philosophy but also in the behavioral and cognitive sciences and in information science. This is highly problematic because it removes the attention from reality to subjective phenomena with no real explanatory power. Realism should not be confused with the view that all scientific claims are true or with any other kind of naiveté concerning knowledge claims. The opposite of realism may be termed antirealism, idealism, or nominalism. Although many people confuse empiricism and positivism with realism, these traditions are by nature strongly antirealist, which is why a sharp distinction should be made between empiricism and realism. Empirical research should not be founded on assumptions about "the given" of observations, but should recognize the theory-laden nature of observations. Domain analysis represents an attempt to reintroduce a realist perspective in library and information science. A realist conception of relevance, information seeking, information retrieval, and knowledge organization is outlined. Information systems of all kinds, including research libraries and public libraries, should be informed by a realist philosophy and a realist information science.

    "Bias" is normally understood as a negatively loaded word, as something to be avoided or minimized, for example, in statistics or in knowledge organization. Recently Melanie Feinberg suggested, however, that "if we cannot eliminate bias, then we should instead attempt to be more responsible about it and explicitly decide on and defend the perspectives represented in information systems". This view is linked to related views: That knowledge organization is too much concerned with information retrieval and too much described in the mode of scientific discovery, as opposed to the mode of artifact design: "From the literary warrant of Hulme to the terminological warrant of the Classification Research Group (CRG), to Hjorland's domain analysis, the classificationist seems like one who documents and compiles, and not one who actively shapes design." This paper examines these claims, which may be understood as questions about subjectivity and objectivity in classification and about positivism versus pragmatism in research. Is KO an objective and neutral activity? Can it be? Should it be? A dominant view has been that knowledge and KO should be understood as a passive reflection øf an external order. This has been termed the mirror metaphor of knowledge and is related to empiricism and positivism. The opposite view which is in accordance with both Feinberg and Hjorland - states that knowledge organization should be functional and thus reflecting given goals, purposes and values. It is related to pragmatism in philosophy.

    Abstract
    In 1971 UNISIST proposed a model for scientific and technical communication. This model has been widely cited and additional models have been added to the literature. There is a need to bring this model to the focus of information science (IS) research as well as to update and revise it. There are both empirical and theoretical reasons for this need. On the empirical side much has happened in the developments of electronic communication that needs to be considered. From a theoretical point of view the domain-analytic view has proposed that differences between different disciplines and domains should be emphasised. The original model only considered scientific and technical communication as a whole. There is a need both to compare with the humanities and social sciences and to regard internal differences in the sciences. There are also other reasons to reconsider and modify this model today. Offers not only a descriptive model, but also a theoretical perspective from which information systems may be understood and evaluated. In addition to this provides empirical exemplification and proposals for research initiatives.

    Abstract
    The aim of this chapter is to demonstrate that semantic issues underlie all research questions within Library and Information Science (LIS, or, as hereafter, IS) and, in particular, the subfield known as Knowledge Organization (KO). Further, it seeks to show that semantics is a field influenced by conflicting views and discusses why it is important to argue for the most fruitful one of these. Moreover, the chapter demonstrates that IS has not yet addressed semantic problems in systematic fashion and examines why the field is very fragmented and without a proper theoretical basis. The focus here is on broad interdisciplinary issues and the long-term perspective. The theoretical problems involving semantics and concepts are very complicated. Therefore, this chapter starts by considering tools developed in KO for information retrieval (IR) as basically semantic tools. In this way, it establishes a specific IS focus on the relation between KO and semantics. It is well known that thesauri consist of a selection of concepts supplemented with information about their semantic relations (such as generic relations or "associative relations"). Some words in thesauri are "preferred terms" (descriptors), whereas others are "lead-in terms." The descriptors represent concepts. The difference between "a word" and "a concept" is that different words may have the same meaning and similar words may have different meanings, whereas one concept expresses one meaning.

    Abstract
    Relationships between Knowledge Organization in LIS and Scientific & Scholarly Classifications In her paper "Classification for Information Retrieval and Classification for Knowledge Discovery: Relationships between 'Professional' and 'Naive' Classifications" (KO v30, no.2, 2003), Beghtol outlines how Scholarly activities and research lead to classification systems which subsequently are disseminated in publications which are classified in information retrieval systems, retrieved by the users and again used in Scholarly activities and so on. We think this model is correct and that its point is important. What we are reacting to is the fact that Beghtol describes the Classifications developed by scholars as "naive" while she describes the Classifications developed by librarians and information scientists as "professional." We fear that this unfortunate terminology is rooted in deeply ar chored misjudgments about the relationships between scientific and Scholarly classification an the one side and LIS Classifications an the other. Only a correction of this misjudgment may give us in the field of knowledge organization a Chance to do a job that is not totally disrespected and disregarded by the rest of the intellectual world.
