    Abstract
    The notion "theory" is a neglected concept in the field of information science and knowledge organization (KO) as well as generally in philosophy and in many other fields, although there are exceptions from this general neglect (e.g., the so-called "theory theory" in cognitive psychology). This article introduces different conceptions of "theory" and argues that a theory is a statement or a conception, which is considered open to be questioned and which is connected with background assumptions. Theories form interconnected systems of grand, middle rank and micro theories and actions, practices and artifacts are theory-laden. The concept of knowledge organization system (KOS) is briefly introduced and discussed. A theory is a form of KOS and theories are the point of departure of any KOS. It is generally understood in KO that concepts are the units of KOSs, but the theory-dependence of concepts brings theories to the forefront in analyzing concepts and KOSs. The study of theories should therefore be given a high priority within KO concerning the construction and evaluation of KOSs.

    Abstract
    Evidence-based practice (EBP) is an influential interdisciplinary movement that originated in medicine as evidence-based medicine (EBM) about 1992. EBP is of considerable interest to library and information science (LIS) because it focuses on a thorough documentation of the basis for the decision making that is established in research as well as an optimization of every link in documentation and search processes. EBP is based on the philosophical doctrine of empiricism and, therefore, it is subject to the criticism that has been raised against empiricism. The main criticism of EBP is that practitioners lose their autonomy, that the understanding of theory and of underlying mechanisms is weakened, and that the concept of evidence is too narrow in the empiricist tradition. In this article, it is suggested that we should speak of "research-based practice" rather than EBP, because this term is open to more fruitful epistemologies and provides a broader understanding of evidence. The focus on scientific argumentation in EBP is an important contribution from EBP to LIS, which is long overdue, but parts of the underlying epistemological assumptions should be replaced: EBP is too narrow, too formalist, and too mechanical an approach on which to base scientific and scholarly documentation.

    Abstract
    The introduction (1.0) of this article considers the status of the thesaurus within LIS and asks about the future prospect for thesauri. The main following points are: (2.0) Any knowledge organization system (KOS) is today threatened by Google-like systems, and it is therefore important to consider if there still is a need for knowledge organization (KO) in the traditional sense. (3.0) A thesaurus is a somewhat reduced form of KOS compared to, for example, an ontology, and its "bundling" and restricted number of semantic relations has never been justified theoretically or empirically. Which semantic relations are most fruitful for a given task is thus an open question, and different domains may need different kinds of KOS including different sets of relations between terms. (4.0) A KOS is a controlled vocabulary (CV) and should not be considered a "perfect language" (Eco 1995) that is simply able to remove the ambiguity of natural language; rather much ambiguity in language represents a battle between many "voices" (Bakhtin 1981) or "paradigms" (Kuhn 1962). In this perspective, a specific KOS, e.g. a specific thesaurus, is just one "voice" among many voices, and that voice has to demonstrate its authority and utility. It is concluded (5.0) that the traditional thesaurus does not have a place in modern information retrieval, but that more flexible semantic tools based on proper studies of domains will always be important.
