    Abstract
    Proposes a new experimental methodology for evaluating the results of library research from the user's viewpoint. Illustrates the theory by comparing the efficacy of information retrieved from 2 document catalogues, identical except that one is alphabetical and the other numerical/verbal. The methodology utilises the concept of 3 dependent variables: 'promising references retrieved' by the researcher; 'documents read'; and 'documents cited'. Claims that the retrieval effectiveness of the techniques outlined compares favourably with that of W.S. Cooper's methodology

    Abstract
    The history of book numbers starts only with Melvil Dewey, as before hom books were shelved in fixed location systems. The article traces the early attempts by Dewey himself to combine class numbers with author numbers and shows the development in the individualization of book numbers by a great number of classificationists and classifiers, among which J. Schwartz, W.S. Biscoe, Ch.A. Cutter, K.E. Sanborn, J.D. Brown, A.F. Rider and finally S.R. Ranganathan whose faceted structure and ease of application of book numbers seems still to be the optimal solution. Two rival systems of book numbers are alphabetical by author and chronological by the year of publication of a books. The concluding chapter is devoted to the existing literatur on book numbers and laments its vanishing quality. The study of book numbers is not getting due attention.

    Abstract
    Describes S.R. Ranganathan's contribution to library and information science in general, mentioning his library education at London and influence of W.C. Berwick Sayers. Describes the seeds of Colon Classification, ed.1 (CC-1) and discusses the salient features of the scheme. Brings out the indebtedness of Ranganathan to Melvil Dewey and describes the influence of UDC on CC-1. Discusses the growth and development of the concept of 'categories', mentioning the influence of W. Hulme, W.S. Biscoe and others. Concludes that Ranganathan possessed an amazing degree of ingenuity to apply established ideas in such a way in a distinctive and original way
