    Abstract
    The problem addressed by this two-part study is to evaluate the quality of Chinese records in the OCLC database and to determine the potential of a set of production rules for a rule-based data validation system lo support quality control of the Chinese records. The second part of the study emphasizes establishing production rules for such a system. Based on the results of error analysis, a set of production rules were developed and tested, focusing on improving completeness, consistency, and correctness of a record. The rules covered 11 of the total 19 types of errors. At least 65% , of the errors occurring in the investigated sample records could be detected automatically by applying the production rules.

    Abstract
    The study consisted of two interrelated parts: (1) a quality analysis of the Chinese-language records in the OCLC database, with emphasis on identifying errors in member-contributed records; and (2) the development of a rule-based data validation system for quality control of Chinese-language records in the OCLC database, with emphasis on establishing a set of production rules for such a system. One thousand three hundred six member-contributed Chinese records were randomly selected from the OCLC database and were examined by the researcher. Commonly occurring errors were identified and were categorized into three classes: format errors, content deficiency and inconsistency errors, and typographical errors of editing and inputting. The relationship between the number of times a record had been enhanced and errors still occurring in it was also studied.

    Abstract
    Compares and evaluates the functional capabilities and interface characteristics of OPACs from the user oriented perspective, using a systematic framework. OPACs of OhioLINK and its 16 member libraries are the object of the investigation. The interfaces used 6 system software but showed a variety of features in access to OPACs, operational control, access points, search formulation control, and user assistance. Interface design alternatives are identified and qualitatively analyzed
