    Abstract
    In the 1970s and 1980s, forms of user-based and cognitive approaches to knowledge organization came to the forefront as part of the overall development in library and information science and in the broader society. The specific nature of user-based approaches is their basis in the empirical studies of users or the principle that users need to be involved in the construction of knowledge organization systems. It might seem obvious that user-friendly systems should be designed on user studies or user involvement, but extremely successful systems such as Apple's iPhone, Dialog's search system and Google's PageRank are not based on the empirical studies of users. In knowledge organization, the Book House System is one example of a system based on user studies. In cognitive science the important WordNet database is claimed to be based on psychological research. This article considers such examples. The role of the user is often confused with the role of subjectivity. Knowledge organization systems cannot be objective and must therefore, by implication, be based on some kind of subjectivity. This subjectivity should, however, be derived from collective views in discourse communities rather than be derived from studies of individuals or from the study ofabstract minds.

    Abstract
    This paper considers classical bibliographic databases based on the Boolean retrieval model (for example MEDLINE and PsycInfo). This model is challenged by modern search engines and information retrieval (IR) researchers, who often consider Boolean retrieval as a less efficient approach. This speech examines this claim and argues for the continued value of Boolean systems, which implies two further issues: (1) the important role of human expertise in searching (expert searchers and "information literacy") and (2) the role of knowledge organization (KO) in the design and use of classical databases, including controlled vocabularies and human indexing. An underlying issue is the kind of retrieval system for which one should aim. It is suggested that Julian Warner's (2010) differentiation between the computer science traditions, aiming at automatically transforming queries into (ranked) sets of relevant documents, and an older library-orientated tradition aiming at increasing the "selection power" of users seems important. The Boolean retrieval model is important in order to provide users with the power to make informed searches and have full control over what is found and what is not found. These issues may also have important implications for the maintenance of information science and KO as research fields as well as for the information profession as a profession in its own right.

    Abstract
    It is with very great pleasure that we introduce this special issue of Knowledge Organization on Domain Analysis (DA). Domain analysis is an approach to information science (IS) that emphasizes the social, historical, and cultural dimensions of information. It asserts that collective fields of knowledge, or "domains," form the unit of analysis of information science (IS). DA, elsewhere referred to as a sociocognitive (Hjoerland, 2002b; Jacob & Shaw, 1998) or collectivist (Talja et al, 2004) approach, is one of the major metatheoretical perspectives available to IS scholars to orient their thinking and research. DA's focus an domains stands in contrast to the alternative metatheories of cognitivism and information systems, which direct attention to psychological processes and technological processes, respectively. The first comprehensive international formulation of DA as an explicit point of view was Hjoerland and Albrechtsen (1995). However, a concern for information in the context of a community can be traced back to American library historian and visionary Jesse Shera, and is visible a century ago in the earliest practices of special librarians and European documentalists. More recently, Hjoerland (1998) produced a domain analytic study of the field of psychology; Jacob and Shaw (1998) made an important interpretation and historical review of DA; while Hjoerland (2002a) offered a seminal formulation of eleven approaches to the study of domains, receiving the ASLIB 2003 Award. Fjordback Soendergaard; Andersen and Hjoerland (2003) suggested an approach based an an updated version of the UNISIST-model of scientific communication. In fall 2003, under the conference theme of "Humanizing Information Technology" DA was featured in a keynote address at the annual meeting of the American Society for Information Science and Technology (Hjorland, 2004). These publications and events are evidence of growth in representation of the DA view. To date, informal criticism of domain analysis has followed two tracks. Firstly, that DA assumes its communities to be academic in nature, leaving much of human experience unexplored. Secondly, that there is a lack of case studies illustrating the methods of domain analytic empirical research. Importantly, this special collection marks progress by addressing both issues. In the articles that follow, domains are perceived to be hobbies, professions, and realms of popular culture. Further, other papers serve as models of different ways to execute domain analytic scholarship, whether through traditional empirical methods, or historical and philosophical techniques. Eleven authors have contributed to this special issue, and their backgrounds reflect the diversity of interest in DA. Contributors come from North America, Europe, and the Middle East. Academics from leading research universities are represented. One writer is newly retired, several are in their heyday as scholars, and some are doctoral students just entering this field. This range of perspectives enriches the collection. The first two papers in this issue are invited papers and are, in our opinion, very important. Anders Oerom was a senior lecturer at the Royal Scbool of 'Library and Information Science in Denmark, Aalborg Branch. He retired from this position an March 1, 2004, and this paper is his last contribution in this position. We are grateful that he took the time to complete "Knowledge Organization in the Domain of Art Studies - History, Transition and Conceptual Changes" in spite of many other duties. Versions of the paper have previously been presented at a Ph.D-course in knowledge organization and related versions have been published in Danish and Spanish. In many respects, it represents a model of how a domain could, or should, be investigated from the DA point of view.
    It uncovers the main theoretical influences that have affected the representation of art in systems of knowledge organization such as LCC, DDC, UDC and the Art & Architecture Thesaurus, and it provides a deep basis for evaluating such systems. Knut Tore Abrahamsen's "Indexing of Musical Genres. An Epistemological Perspective" is a modified version of a thesis written at the Royal School of Library and Information Science in Copenhagen. As a thesis it is a major achievement which successfully combines knowledge of music, epistemology, and knowledge organization. This paper may also be seen as an example of how domains can be analyzed and how knowledge organization may be improved in practice. We would like to thank Sanna Talja of the University of Tampere, among other people, for Input an this piece. And now to the rest of the issue: Olof Sundin's "Towards an Understanding of Symbolic Aspects of Professional Information: an Analysis of the Nursing Knowledge Domain" contributes to DA by introducing a deeper understanding of the notion of professions and by uncovering how in some domains, "symbolic" functions of information may be more important than instrumental functions. Rich Gazan's: "Metadata as a Realm of Translation: Merging Knowledge Domains in the Design of an Environmental Information System" demonstrates the problems of merging data collections in interdisciplinary fields, rohen the perceived informational value of different access points varies with disciplinary membership. This is important for the design of systems of metadata. Joe Tennis': "Two Axes of Domains for Domain Analysis" suggests that the notion of domain is underdeveloped in DA. Tennis states, "Hjoerland has provided a hammer, but rohere are the nails?" In addition he raises a question concerning the degree of specialization within a domain. He resolves these issues by proposing two new "axes" to DA. Chaim Zins & David Guttmann's: "Domain Analysis of Social Work: An Example of an Integrated Methodological Approach" represents an empirical approach to the construction of knowledge maps based an representative samples of the literature an social work. In a way, this paper is the most traditional or straightforward approach to knowledge organization in the issue: It suggests a concrete classification based an scientific norms of representation and objectivity.
    Hanne Albrechtsen & Annelise Mark Pejtersen's: "Cognitive Work Analysis and Work Centered Design of Classification Schemes" is also based an empirical studies, but focuses an work groups rather than literatures. It claims that deep semantic structures relevant to classification evolve dynamically in work groups. Its empirical method is different from Zins & Guttmann's. Future research must further uncover the relative strengths and weaknesses of literatures versus people in the construction of knowledge organizing systems. Jenna Hartel's: "The Serious Leisure Frontier in Library and Information Science: Hobby Domains" expands DA to the field of "everyday information use" and demonstrates that most of the approaches suggested by Hjoerland (2002a) may also be relevant to this field. Finally, Birger Hjoerland & Jenna Hartel's After-word: Some Basic Issues Related to the Notion of a Domain" suggests that the notions of ontology, epistemology, and sociology may be three fundamental dimensions of domains and that these perspectives may clarify what domains are and the dynamics of their development. While this special issue marks great progress, and the zenith of DA to date, the approach remains emergent and there is still much work to be done. We see the need for ongoing domain analytic research along two paths. Remarkably, to our knowledge no domain has been thoroughly studied in the domain analytic view. The first order, then, is rigorous application of DA to multiple domains. Second, theoretical and methodological gaps presently exist; these are opportunities for creative inventors to contribute original extensions to the approach. We warmly invite all readers to seriously engage with these articles, whether as critics, spectators, or participants in the domain analytic project.

    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
    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 paper investigates the problem of the labelling of the library, documentation and information field with particular emphasis on the terms 'information' and 'document'. What influences introduced the concept of 'information' into the library field in the middle of the 20th century? What kind of theoretical orientation have dominated the field, and how are these orientations linked to epistemological assumptions? What is the implication of the recent influence of socially oriented epistemologies for such basic concepts in IS as 'information' and 'document'? The article explores these problems and advocates an approach with emphasis on documents and on the concept 'memory institution' as generic term for the central object of study

    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.

    Abstract
    Purpose - The purpose of this article is to introduce the special issue of Journal of Documentation about library and information science (LIS) and the philosophy of science. Design/methodology/approach - The most important earlier collected works about metatheories and philosophies of science within LIS are listed. Findings - It is claimed that Sweden probably is the country in which philosophy of science has the highest priority in LIS education. The plan of the guest editor was that each epistemological position should be both introduced and interpreted in a LIS context together with a review of its influence within the field and an evaluation of the pros and cons of that position. This was only an ideal plan. It is argued that it is important that such knowledge and debate are available within the LIS-literature itself and that the answers to such questions as "What is positivism?" are not trivial ones. Originality/value - The introduction is written to assist readers overviewing the issue and share the thoughts of the editor in planning the issue.

    Abstract
    The domain-analytic approach to knowledge organization (KO) (and to the broader field of library and information science, LIS) is outlined. The article reviews the discussions and proposals on the definition of domains, and provides an example of a domain-analytic study in the field of art studies. Varieties of domain analysis as well as criticism and controversies are presented and discussed.

    Abstract
    Purpose - The purpose of this paper is to examine the importance and influence of the epistemologies: "empiricism", "rationalism" and "positivism" in library and information science (LIS). Design/methodology/approach - First, outlines the historical development of these epistemologies, by discussing and identifying basic characteristics in them and by introducing the criticism that has been raised against these views. Second, their importance for and influence in LIS have been examined. Findings - The findings of this paper are that it is not a trivial matter to define those epistemologies and to characterise their influence. Many different interpretations exist and there is no consensus regarding current influence of positivism in LIS. Arguments are put forward that empiricism and positivism are still dominant within LIS and specific examples of the influence on positivism in LIS are provided. A specific analysis is made of the empiricist view of information seeking and it is shown that empiricism may be regarded as a normative theory of information seeking and knowledge organisation. Originality/value - The paper discusses basic theoretical issues that are important for the further development of LIS as a scholarly field.

    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
    This paper considers classical bibliographic databases based on the Boolean retrieval model (such as MEDLINE and PsycInfo). This model is challenged by modern search engines and information retrieval (IR) researchers, who often consider Boolean retrieval a less efficient approach. The paper examines this claim and argues for the continued value of Boolean systems, and suggests two further considerations: (a) the important role of human expertise in searching (expert searchers and "information literate" users) and (b) the role of library and information science and knowledge organization (KO) in the design and use of classical databases. An underlying issue is the kind of retrieval system for which one should aim. Warner's (2010) differentiation between the computer science traditions and an older library-oriented tradition seems important; the former aim to transform queries automatically into (ranked) sets of relevant documents, whereas the latter aims to increase the "selection power" of users. The Boolean retrieval model is valuable in providing users with the power to make informed searches and have full control over what is found and what is not. These issues may have significant implications for the maintenance of information science and KO as research fields as well as for the information profession as a profession in its own right.

    Abstract
    Recently, a new book on knowledge organization has been published by Greenwood Press. The title is 'Information seeking and subject representation: an activity-theoretical approach to information science'. This book presents a new general theory for information science and knowledge organization, based on a theory of information seeking. The author is Dr. Birger Hjørland, Royal School of Library and Information Science. In 1994, he presented his work on theory for KO at the 3rd International ISKO conference in Copenhagen. The book aims to provide both a new understanding for the foundations of information science and knowledge organization, and to provide new directions in research and teaching within these fields. KO (Hanne Albrechtsen) has interviewed Birger HjÝrland in Copenhagen about his views on knowledge organization and subject representation

    Abstract
    In spring 2002 I started teaching Knowledge Organization (KO) at the new master education at The Royal School of Library and Information Science in Copenhagen (MS RSLIS). I began collecting information about KO as support for my own teaching and research. In the beginning I made the information available to the student through a password protected system "SiteScape". This site was a great success, but I encountered problems in transferring the system for new classes the following years. Therefore I have now decided to make it public on the www and to protect only information that should not be made public. References freely available in electronic form are given an URL (if known).

    Abstract
    This article presents and discusses the concept "subject" or subject matter (of documents) as it has been examined in library and information science (LIS) for more than 100 years. Different theoretical positions are outlined and it is found that the most important distinction is between documentoriented views versus request-oriented views. The documentoriented view conceives subject as something inherent in documents, whereas the request-oriented view (or the policybased view) understands subject as an attribution made to documents in order to facilitate certain uses of them. Related concepts such as concepts, aboutness, topic, isness and ofness are also briefly presented. The conclusion is that the most fruitful way of defining "subject" (of a document) is the document's informative or epistemological potentials, that is, the document's potentials of informing users and advancing the development of knowledge.

    Abstract
    The concept of information as we use it in everyday English, in the sense of knowledge communicated, plays a central role in contemporary society. The development and widespread use of computer networks since the end of World War II, and the emergence of information science as a discipline in the 1950s, are evidence of this focus. Although knowledge and its communication are basic phenomena of every human society, it is the rise of information technology and its global impacts that characterize ours as an information society. It is commonplace to consider information as a basic condition for economic development together with capital, labor, and raw material; but what makes information especially significant at present is its digital nature. The impact of information technology an the natural and social sciences in particular has made this everyday notion a highly controversial concept. Claude Shannon's (1948) "A Mathematical Theory of Communication" is a landmark work, referring to the common use of information with its semantic and pragmatic dimensions, while at the same time redefining the concept within an engineering framework. The fact that the concept of knowledge communication has been designated by the word information seems, prima facie, a linguistic happenstance. For a science like information science (IS), it is of course important how fundamental terms are defined; and in IS, as in other fields, the question of how to define information is often raised. This chapter is an attempt to review the status of the concept of information in IS, with reference also to interdisciplinary trends. In scientific discourse, theoretical concepts are not true or false elements or glimpses of some element of reality; rather, they are constructions designed to do a job in the best possible way. Different conceptions of fundamental terms like information are thus more or less fruitful, depending an the theories (and in the end, the practical actions) they are expected to support. In the opening section, we discuss the problem of defining terms from the perspective of the philosophy of science. The history of a word provides us with anecdotes that are tangential to the concept itself. But in our case, the use of the word information points to a specific perspective from which the concept of knowledge communication has been defined. This perspective includes such characteristics as novelty and relevante; i.e., it refers to the process of knowledge transformation, and particularly to selection and interpretation within a specific context. The discussion leads to the questions of why and when this meaning was designated with the word information. We will explore this history, and we believe that our results may help readers better understand the complexity of the concept with regard to its scientific definitions.

    Abstract
    This article presents a theoretical investigation of the concept of 'subject' or 'subject matter' in library and information science. Most conceptions of 'subject' in the literature are not explicit but implicit. Various indexing and classification theories, including automatic indexing and citation indexing, have their own more or less implicit concepts of subject. This fact puts the emphasis on making the implicit theorie of 'subject matter' explicit as the first step. ... The different conceptions of 'subject' can therefore be classified into epistemological positions, e.g. 'subjective idealism' (or the empiric/positivistic viewpoint), 'objective idealism' (the rationalistic viewpoint), 'pragmatism' and 'materialism/realism'. The third and final step is to propose a new theory of subject matter based on an explicit theory of knowledge. In this article this is done from the point of view of a realistic/materialistic epistemology. From this standpoint the subject of a document is defined as the epistemological potentials of that document

    Abstract
    Purpose - The purpose of this afterword is to examine which questions have been illuminated in the present issue and which theoretical problems still need to be addressed. Design/methodology/approach - Examines articles in this issue. Findings - Many epistemological views, e.g. social constructivism, critical theory, feminist epistemology, postmodernism and systems theory, need to be considered more deeply within library and information science (LIS). For some of the other epistemologies such as phenomenology and (post)structuralism there is still a need for deeper explorations of their potential contributions. Finally eclecticism is discussed as one way of coping with different theories in a field. Originality/value - The value of this afterword is to contribute to future reflections and debates concerning the philosophical basis of LIS and the specific contributions of specific systems of thought.
