    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

    Abstract
    The literature of psychology, library science, management, computer science, and systems engineering is reviewed and integrated into an overall perspective of human information seeking and the design of information systems. The nature of information seeking is considered in terms of its role in decision making and problem solving, the dynamics of the process, and the value of information. Discussions of human information seeking focus on basic psychological studies, effects of cognitive style, and models of human behavior. Design issues considered include attributes of information systems, analysis of information needs, aids for information seeking, and evaluation of information systems

    Abstract
    The argumetns of Pt.1-3 are applied to two main issues: (a) the separation of the physical and mental components of information phenomena, illustrated by a discussion of the aging of periodicals, (b) the role of the Bradford Law and ranking techniques as a means of exploiting all the information inherent in the raw data. The paper concludes with a brief discussion of a propsed new kind of data-base in which objective information is structured into objective knowledge

    Abstract
    It is first argued that a niche for information science, unclaimed by any other discipline, can be found by admitting the near-autonomy of Popper's World III - the world of objective knowledge. The task of information science can then be defined as the exploration of this world of objective knowledge which is an extension of, but is distinct from, the world of documentation and librarianship. The Popperian ontology then has to be extended to admit the concept of information and its relations to subjective and objective knowledge. The spaces of Popper's three worlds are then considered. It is argued that cognitive and physical spaces are not identical and that this lack of identity creates problems for the proper quantification of information phenomena

    Abstract
    An outline history describes how man has extended the process of objectivization from everyday practicalities to modern science. Modern techniques of quantification awaited the adoption of the Hindu-Arab numerals and the creation of a calculus for their use. It is argued that the use of these numerals has provided analytical instruments which, though ideally adapted to the exploration and exploitation of the physical world, fail to capture important aspects of the individuality of response within groups which humans display in their social behaviour. New quantitative techniques more sensitive to these aspects are therefore needed in the social sciences. A numerical example is used to illustrate how frequency-rank statistics make fuller use of empirical information in the social sciences than conventional statistics which, by using classes, discards information related to individuality

    Abstract
    This article clarifies the idea of information by dividing the whole range of its definitions into different parts and by identifying several points of misunderstanding. it explores the sciences relating to the concept to information by classifying sciences in terms of their relevance to different ranges of information definitions and by distinguishing the relationship among them. The nomenclatures of informatics, informatology, information science, and information sciences are discussed in particular. The multidimensional properties of the concept "information" and the multidimensional relationships of the relevant sciences are illustrated with diagrams

    Abstract
    Discusses the apparent need for a set of rigorous definitions of basic concepts and argues that though this is necessary for natural sciences it is not needed in behavioural schiences which have a prior description in natural language. Information science should be more interested in uncertainty than knowledge. Shows how the anomalous state of knowledge paradigm can be used to describe itself and thus also information science. Turning to problems of uncertainty can prevent information science from following the mistakes of psychology
