    Abstract
    Suggests a user based approach to system design and evaluation, of computerized library systems (e.g. OPACs), which is application specific. Data was collected on 93 end user interactions with a newly implemented OPAC in a large US university library. Concludes that researchers need to explore questions relating directly to problems, faced by users and to present findings in ways which provide action oriented recommendations

    Abstract
    Suggests that an appropriate method for evaluating information retrieval systems is to focus on the individual actions users attempts to perform on a system. The evaluation criterion 'degree of match' between attempted actions and actual system commands is one of a series of evaluation measures including perceived measures and summary measures that were investigated. Results indicate that there is the potential for significant improvement of the OPAC's interface, particularly those parts of the interface which concern searching and revision activities
