The findings of the CLR-OPAC studies and the major OPAC user studies are analyzed and sythesized. They are described, dividing into three categories: characteristics of users, user instruction, and user interface. Data gathering methods, and their strengths and weaknesses are also discussed.

As the OPAC has been changed by the automation of library catalog, AACR2 recognized as internationally standardized Cataloging Rules, and MARC transforming to automation program have some partial irrationality. In this study, I presented the methodology improving practically and specifically Cataloging Rules adjusted to Online environment, especially centering on AACR2R, after I reviewed the literature asserting a criticism and a renewal of AACR2 and MARC.

In this study in order to verify the overall information seeking behavior of the Web-based OPAC users, it was analyzed transaction log file for 7 years. Regarding Web-based OPAC information seeking behavior, it was studied from the perspective of information seeking strategy and information seeking failure. In search strategy, it was analyzed search type, search options, Boolean operator, length of search text, number of uses of word, number of use Web-based OPAC, number of use by time, by week day. Also, in search failure, search failure ratio, search failure ratio by search options, search failure ratio by Boolean operator were analyzed. The result of this study is expected to be utilized for OPAC system and service improvement in the future.

The purpose of this study is to evaluate the characteristics of user interface that affect the searching behavior of OPAC users. and then to propose how to design user-friendly interfaces of OPACS. An experiment was conducted on two systems with different interfaces to grasp the effect of user interface to search process and search outcome. A $2\times2$ cross-over design was used for the experiment. Sixty five searchers participated in the experiment. Several statistical techniques such as carry-over effect and system effect of a $2\times2$ cross-over design, $\chi^2$ test, t- test, McNemar test, test of marginal homogeneity through maximum likelihood method, factor analysis, regression analysis, and analysis of variance were applied according to the hypotheses tested and the data analyzed.

This study examined the main concepts of SOA and Web Services, and conducted technical analysis of major Web Services protocols such as SOAP, REST, SRW/U, and OAI-PMH that realize SOA, and suggested examples of SOAP and REST based Web Services establishments in foreign and domestic libraries respectively. In addition, it introduced application examples of Library 2.0 using Web 2.0 technology in foreign and domestic libraries and suggested how to apply SOA based Web Services protocol in Library 2.0. Finally, it proposed how to put Library 2.0 into practice applying meta-searching system integrating library OPAC, online bookstores, web portal sites and library union catalogs using REST based Open API.

This study is to develop a hierarchic clustering model fur document classification and browsing in OPAC systems. Two automatic indexing techniques (with and without controlled terms), two term weighting methods (based on term frequency and binary weight), five similarity coefficients (Dice, Jaccard, Pearson, Cosine, and Squared Euclidean). and three hierarchic clustering algorithms (Between Average Linkage, Within Average Linkage, and Complete Linkage method) were tested on the document collection of 175 books and theses on library and information science. The best document clusters resulted from the Between Average Linkage or Complete Linkage method with Jaccard or Dice coefficient on the automatic indexing with controlled terms in binary vector. The clusters from Between Average Linkage with Jaccard has more likely decimal classification structure.

The aim of this study is to propose a development plan of public library OPAC interface. For this purpose, the study analyzed cases of OPAC interface of domestic and overseas public libraries, and took a questionnaire survey on use types, level of functional demand and improvement matters of OPAC in order to examine the user requirements on OPAC interface. Public library OPAC interface must comply with interface design principle and reflect requirements of users. Accordingly, it must supply foundation to realize various OPAC functions by inputting perfect bibliographic records on resources. The research result could be used as basic resources for the public library OPAC interface design.

Currently, most academic libraries provide OPAC 2.0 service which applies Web 2.0 based-internet search engine to OPAC. The new service is for the users' convenience and so the considerations for the users' opinions are of great importance for each of services. The objectives of the study were to investigate perceptions of the students as the main user for academic library on the importance for the main services of OPAC 2.0 and analyzed information sources and the reasons for book search by the virtue of this service. The study showed that there were the users' high expectations on accuracy and satisfaction for OPAC 2.0, and the main searching information source was the OPAC of the universities to which the users belong due to familiar screen as well as convenient reading and book loan through it. The OPAC 2.0 service needs to be improved with the consideration of the users' opinions.

To understand and analyze the variety of the subject access methods of OPACs, telephone interviews were administered to the computerized libraries in Seoul. Data was collected during 4 days in Feb. 1997, and 155 libraries were responded. It was found that 105 libraries are operating OPACs. Among the 105 libraries, almost of all provide classification number and title keyword access, however, only half of them provide subject name access. 18 libraries allow linking/browsing facility between classification number and subject name/keyword. The language of the subject name to oriental books is mainly Korean and that to the Western books is mainly English. LCSH is the major authority list used. 36 libraries, 2/3 of them are special libraries, subject name is assigned by librarian without control. Based on the results, problems and suggestions to enhance subject access capability are presented.
