    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
