    Abstract
    The theory of fuzzy sets is used to provide a rogorous formulation of the problem of associative retrieval. This formulation suggests the idea of using fuzzy clustering to organize data for retrieval

    Abstract
    We have investigated the relative merits of searching on titles, subject headings, abstracts, free-language terms, and combinations of these elements. The COMPENDEX data base was used for this study since it combined all of these data elements of interest. In general, the results obtained from the experiments indicate that, as expected, titles alone are not satisfactory for efficient retrieval. The combination of titles and abstracts came the closest to 100% retrieval, with searching of abstracts alone doing almost as well. Indexer input, although necessary for 100% retrieval in almost all cases, was found to be relatively unimportant

    Abstract
    Seeking to document the extent to which libraries of four-year colleges and universities have adopted the LCC system, this study surveys the classification systems used by the libraries of 1.160 accredited four-year-colleges and universities. The LC system is presently being used by more than half of these libraries; however, throughout 1968-71 the "trend to LC" clearly lost momentum. Data are provided on the extent to which the Library of Congress and The DDC systems were used in 1967 and 1971 by libraries of various sizes and categories

    Abstract
    The inverted file structure is often used to organize data in the information retrieval system. When the hierarchy relation on the set descriptors and weights of descriptors in document description would be taken into account, the conventional concept of the inverted file may be extended. Properties and operations on inverted files, which are used in systems based on thesaurus with weights, are studied in this paper

    Abstract
    Introductory paper in an issue devoted to theory and foundation of information retrieval. There are too many records to be handled rationally and comfortably. Too much is badly written or repeats what has been adequately stated before. Automated retrieval systems may help society to cope with some information problems, but truly effective systems could help much more. This issue deals (through an examination of the theory and foundations of information retrieval) with how effective information retrieval systems could be designed and discusses important issues of data retrieval

    Abstract
    Results in the literature concerning the probability that an author publishes r articles in time t are reexamined, and it is found that a negative binomial distribution bits scientific productivity data (by the chi-squared goodness-of-fit-test) better than many other distribution such as geometric, logarithmic, zeta, cumulative advantage, etc. It is shown analytically that the nagative binomial distribution describes a pattern of scientific productivity under the 'success-breeds-success' condition in a wide variety of social circumstances

    Abstract
    Salient node notation is a technique for decreasing the average length of notation in a classification scheme without sacrficing expressiveness or disturbing the succession of chracteristics of the filing order. Assignment of notation begins at a node of the classification tree other than the root. This salient node may be determined algorithmically, given data on the bias of the collection to be classified, even if only part of the tree has been developed. A dummy value is reserved to indicate upward movement in the tree. The technique is especially applicable to classification schemes for spevialized collections and to facets such as space in which the biases of human existence are especially prominent

    Abstract
    Interdisciplinary associations laed to the emergence of hybrid disciplines. Interdisciplinary association may be of two types - multi-disciplinary associations and interdisciplinary borrowing. Multi-disciplinary association may be juxtaposition studies or convergence of view points. Interdisciplinary borrowing involves borrowing of techniques and tools, or borrowing of data, or use of principles and theories. The emergence of hybrid discipline pose problems in classification. Some of these problems are highlighted by taking the newly emerging discipline of cycle research as a case study. Cycle research is a general theoretical study of cycle phenomena. It can be deemed to be formed by either of the two modes of formation namely distillation and clustering. In Colon Classification, ed.7, cycle research may be accomodated in the schedule of personality isolates in the basic subject BTM time series analysis
