    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
    Examines a simpler cataloguing format offered by PCs, without disturbing compatibility, using A-Z cataloguing rules for data input, category codes for tagging and computer-supported data input through windows. Gives numerous examples of catalogue entries, basing techniques on certain category schemes set out by Klaus Haller and Hans Popst. Examines catalogue entries in respect of categories of data bases for authors and corporate names, titles, single volume works, serial issues of collected works, and limited editions of works in several volumes.

    Abstract
    This short guide describes the process for creating a CD-ROM based üublic access catalog. The authors admit that the material will be outdated by the time of publication, because product specifics change so rapidly. The report is useful, but not completely thorough. Disadvantages to using CD-ROM for public access catalog are listed, but existing methods to overcome these hindrances are not mentioned. The paper also touches on the possibility that CD-ROM-based catalogs may be more than simply an extra service, that they may become full-service catalogs in themselves

    Abstract
    The authors conducted a six-week queueing study of public catalogs in the Iowa State University library system. Data gathered are analyzed primarily to determine if routinely gathered library statistics can validly be used to predict catalog usage, to discover the ratio between the usage of the card catalog and the serials catalog, and to pinpoint the time of peak card catalog usage in order to measure more closely the rate of use. This measurement, then, provides one factor in a simulation model that can be constructed to predict accurately the number of devices needed for an alternative catalog format

    Abstract
    Definition and Scope For the purpose of this reader, subject analysis is understood to encompass vocabulary structuring and subject indexing. Vocabulary structuring refers to the constructing of tools, such as classifications, subject heading lists, and thesauri, designed to facilitate the organization and retrieval of information. These tools, though called by different names, are similar in that they structure or control the basic vocabulary of a subject index language by 1) stipulating terms that may be used in the classing or indexing of documents and 2) displaying semantic relationships, such as hierarchy and synonymy, that obtain between these terms. They differ in the kinds of terms and relationships they recognize and in the manner in which these are displayed. Subject indexing refers to the application of a vocabulary, which may be more or less well structured, to indicate the content or aboutness of documents. Traditionally subject indexing limits its domain to only certain types of documents, such as passages within books (back-of-book indexing) or periodical articles, and the expression it uses to only certain types of strings, for example, descriptors or index terms as opposed to subject headings or class numbers. However, in a generalized and more modern sense, subject indexing refers to the indication of the theme or topic of any document, indeed any retrieval artifact, by any meaningful string of alphanumeric characters. The value of construing the meaning of subject analysis broadly is threefold: it permits comparing a variety of approaches to subject analysis; it permits generalizing about these approaches at a relatively high descriptive level, so that principles and objectives are shown in relief; and, most importantly perhaps, it permits a unified view of the traditional and information scientific approaches to subject analysis.
    Criteria for Selection In selecting the writings to be included in this reader, we have followed the criteria listed below: 1. Theoretical emphasis. Our focus is an theoretical and philosophical aspects rather than practical or technical considerations. In a number of cases, where several authors have written an the same subject or idea or expressed similar thoughts, the originator of the idea, if this could be determined, was selected. 2. Significance and impact. Our most important criterion is the significance of a particular piece or the contribution that it has made in the field of subject analysis. The impact of the ideas or concepts an subsequent practice in subject analysis has also been considered. 3. Perspicuity. Where multiple choices were available an a particular topic or area, our tendency was to exclude the writings that are obscure or highly technical and would require a high degree of tech nical sophistication an the part of the reader. Comprehensibility and clarity of style were often our guide. Based an the criteria stated above, the following types of writings have generally been excluded: review articles, the how-to-do-it type of writings, and textbook materials. In a way, it would probably be easier to defend the writings that have been included than to justify the exclusions. In a small volume containing writings chosen from a vast amount of available material, it is virtually impossible to arrive at a collection that will satisfy every reader. Each person has his or her own preferences or criteria. Inevitably, personal bias comes into play in assembling such a reader. At least, we hope that in this case the collective bias of three individuals rather than one has helped to provide a certain degree of balance. A number of writings originally selected for inclusion were omitted because of space limitation or failure to secure permission to reprint.
