    Abstract
    This book seeks to complement two major works on the subject published in the U.S.A.by devoting it self tochronological book numbers. It is mostly an ignored rival line to alphabetical book numbers, indeed an ignored subject. The first four chapters dwell on the theoretical and general problems of book numbers, indeed an ignored subject. the first four chapters dwell on the tehoretical and general problem of book numbers: their definition, nature , usefulness and history. The chapter on the debate over the usefulness of book numbers tries to give the readersa taste of the debate that followed their conceptionand immediate development. Chapter four catalogues advantages of chronological book numbers. The remaining four chapters dwell upon the four specific chronollgical book numbering system. The desription of each system is prefaced by a brief life sketch of the inventor. Ranganathan's system has been fully but concsely explained. The other systems are by W.S.Biscoe, J. D. Brown, Fremont Rider and W.S. Rider and W.S. Merrill. There are twoappendices: one onthe chronology of book numbers (1873-1992), and another an almost exhaustive bibliography on the subject. Its aim is to invite the attention of scholars to a neglected part of our heritage.

    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
    W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users
