    Abstract
    Different approaches to the classification of a knowledge field include empiristic, rationalistic, historistic, and pragmatic methods. This paper demonstrates how these different methids have been applied to the classification of psychology. An etymological apporach is insufficient to define the subject matter of psychology, because other terms can be used to describe the same domain. To define the subject matter of psychology from the point of view of its formal establishment as a science and academic discipline (in Leipzig, 1879) it is also insufficient because this was done in specific historical circumstances, which narrowed the subject matter to physiologically-related issues. When defining the subject area of a scientific field it is necessary to consider how different ontological and epistemological views have made their influences. A subject area and the approaches by which this subject area has been studied cannot be separated from each other without tracing their mutual historical interactions. The classification of a subject field is theory-laden and thus cannot be neutral or ahistorical. If classification research can claim to have a method that is more general than the study of concrete developments in the single knowledge fields the key is to be found in the general epistemological theories. It is shown how basic epistemological assumptions have formed the different approaches to psychology during the 20th century. The progress in the understanding of basic philosophical questions is decisive both for the development of a knowledge field and as the point of departure of classification. The theoretical principles developed in this paper are applied in a brief analysis of some concrete classification systems, including the one used by PsycINFO / Psychologcal Abstracts. The role of classification in modern information retrieval is also briefly discussed

    Abstract
    Report on the conference on Information Authority and user knowledge held in Boras Apr 93 and arranged by Gothenburg University's Centre for Library and Information Science and Studies and Boras Library High School. The main speaker, Patrick Wilson, spoke on consequences of information overload and rapid conceptual change. Johan Olaisen's talk on 'toward a theory of clarified subjectivity' started like Wilson's with the problem that users of information systems drown in trivialities. Lena Olsson's dealt with library work in practice and commented on the connection between cognitive authority and professional status of librarians. Discussions centered on the definition of information authority, and on overload as the driving force in IF development

    Abstract
    Information science (IS) is concerned with the searching and retrieval of text and other information (IR), mostly in electronic databases and on the Internet. Such databases contain fulltext (or other kinds of documents, e.g. pictures) and/or document representations and/or different kinds of 'value added information'. The core theoretical problems for IS is related to the determination of the usefulness of different 'subject access points' in electronic databases. This problem is again related to theories of meaning and semantics. This paper outlines some important principles in the design of documents done in the field of 'composition studies'. It maps the possible subject access points and presents research done on each kind of these. It shows how theorie of IR must build on or relate to different theories of concepts and meaning. It discusses 2 contrasting theories of semantics worked out by Ludwig Wittgenstein: 'the picture theory' and 'the theory od language games' and demonstrates the different consequences for such theories for IR. Finally, the implications for information professionals are discussed

    Abstract
    Information science has for a long time been drawing on the knowledge produced in psychology and related fields. This is reasonable, for the central issue in information science concerns individual users navigating information spaces such as libraries, databases, and the Internet, Thus, informations seeking is the fundamental problem in information science, while other problems, such as document representation, are subordinate. This book proposes a general theory of information seeking as a theoretical basis for information science

    Abstract
    This paper takes a second look at three prevailing main themes in knowledge organization: i) the academic disciplines as the main structural principle; ii) the fiction/non-fiction distinction; and iii) the appropriate unit of analysis in online retrieval systems. The history and origin of bibliographic classification [Dewey, Bliss, Mills, Beghtol] are discussed from the perspective of pragmatist philosophy and social studies of science [Kuhn, Merton, Reich]. Choices of structural principles in different schemes are found to rely on more or less implicit philosophical foundations, ranging from rationalism to pragmatism. It is further shown how the increasing application of faceted structures as basic structural principles in universal classification schemes [DDC, UDC] impose rationalistic principles and structures for knowledge organization which are not in alignment with the development of knowledge in the covered disciplines. Further evidence of rationalism in knowledge organization is the fiction/non-fiction distinction, excluding the important role of artistic resources for, in particular, humanistic research. Finally, for the analysis of appropriate bibliographic unit, it is argued that there is a need to shift towards a semiotic approach, founded on an understanding of intertextuality, rather than applying standard principles of hierarchical decomposition of documents. It is concluded that a change in classification research is needed, founded on a more historical and social understanding of knowledge
