The purpose of this study is to examine the utilization of university libraries Web OPACs. As a sample group, 51 university libraries are selected and classified to 9 common types. The nine types of Web OPACs are analyzed； operational characteristics, access points, search types, output formats and help functions. The results of this study can be used towards the interface designs of Web OPACS.

The purpose of this study is to examine the service of Web OPACs in public libraries. Thirty-eight public libraries are grouped into eight class by the type of system and user interface. The Libraries in the eight class of them are analyzed by five characteristics. The result of this study shows that both functions and interface design of the Web OPACs in public library need to be improved for them.

The aim of this study was to discover the correlation between users cognitive style and their attitude towards evaluating the system. Postgraduate students cognitive styles were defined as Verbaliser/Imager and Wholist/Analytic, and the functionality and ease of learning features of a Web-based OPAC(Online Public Access Catalogue) system were evaluated using a combined evaluation methods: interviews for the preliminary survey, a questionnaire far the central data collection, and a psychometric approach for the judgement of students cognitive style using Ridings CSA(Cognitive Style Assessment) tool. Forty-four postgraduate student volunteers responded and data was analysed using SPSS(Statistical Package for Social Science) for Windows. The statistical analysis of each feature of the evaluation, the correlation between the variables, and the features were explored using Pearsons correlation coefficients(r). In exploring the effects of the cognitive styles of individuals, this study has failed to reveal a significant (P < 0.05) correlations in the interactive Web-based OPACs evaluation. It could be said that the contribution of cognitive styles to evaluating Web-based OPACs is likely to be weaker than that of non-cognitive (or demographic) variables.

This paper examines the correlations between user characteristics and their perferences for two selected features of Web-based OPAC systems. User characteristics identified in this study were age, gender, educational status, computer skills and OPAC experience. Usability features included interaction styles, character and image on screen, browsing and navigating style, screen layout, and ease of learning, whereas availability features attended to availability of information, quality of information and up-to-date information. Individual variables and features are described, and the correlation between the variables and the features are explored using Pearson's correlation coefficient(r). Although based on a small-scale sample survey, a considerably large number of statistically significant correlations were found between the users' characteristics and the selected evaluation features of interactive Web-based OPACs. From these observations, it seems to be suitable to recommend that system designers should make a more considered appraisal of the users' demographic characteristics in the design of the new generation of OPAC such as in user-tailored interactive Web-based OPAC systems.

The purpose of this study is to investigate the correlation between users' preferences of Personality types and their attitude towards patterns of Web OPAC use mainly focus on their search behaviour and their preferences for the interface. Data res collected through the MBTI test and self-designed online questionnaire. The original MBTI personality types were re-coded into 4 categories of preferences of personality types, that is, E(Extraversion), I(Introversion), S(Sensing), N(iNtuition), T(Thinking)-F(Feeling), and J(Judging)-P(Perception) and then analysed their correlation with patterns of Web OPAC use by Person's correlation coefficient (r) in SPSS Windows Ver. 11.0. It is noteworthy that 9 out of 28 factors of Web OPAC search behaviour and preferences for interfaces show statistically significant correlation with users' MBTI preferences of personality types.

The purpose of this study is to examine how the titles and corporate names of Japanese scholarly journals are treated, and how well the authority control is implemented to assist the access with various names and forms of names to the OPACS. Without the help of either references or internal links among those names and forms of names in the DBs, users are likely to fail in getting the right results. In this study, the cataloging records for serials from the National Assembly Library, KISTI, Yonsei University and the KERIS were examined, and the comparison was made with the records from the NACIS-WebCat of the National Institute of Informatics in Japan. Major findings include (1) the lack of consistency in applying cataloging rules, (2) the lack of proper authority control in treating corporate names, and (3) the lack of references or links among names and variant forms of names. The overall improvement of cataloging practices and application of authority control is strongly recommended for enabling users to access better to those DBs of interest.
