    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 Political Sciences Library of the University of Padua completed in 1994 a pilot project to add all its book material purchased since 1970 (some 20.000 monographs) to its public online catalogue. The library decided against creating a parallel database, and to work instead directly thorugh its existing SBN base, thus avoiding duplication of authors and titles and saving time. Library of Congress tapes were acquired and a special rapid cataloguing software (RAP) was developed, written in natural-Adabas. Describes the project's methodology, problems and results
