    Abstract
    Althogh the library literature contains numerous papers on the functional and performance evaluation of OPACs, as well as on the evaluation of many facets of reference service, it presents little assistance for the evaluation of OPACs as the central facet of reference service. In order to alleviate this lack, evaluates OPACs as if they were any other reference tool, judging them against Norman D. Stevens' classic 18 criteria for the evaluation of reference books. Includes a selective bibliography of works on both OPAC and reference book evaluation
