    Abstract
    Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth
