This study surveyed the online catalog retrieval systems of the university libraries in Busan, Ulsan, Gyeongnam districts. The types of library materials, and the kinds of access points and retrieval conditions(Boolean logic, methods of index term Identification, and particularities of the retrieval) of these systems are various and different to each other Upon the result of this survey a suggestion for the standardization of online catalog retrieval systems is offered.

The purpose of this study is aimed to clarify the usefulness of meta search system using Open API of library online catalog by constructing OPAC-based search system using Open API of library online catalog and meta search system using Open API of library online catalog, and comparing the usability of the two experimental search systems. As for usability, on the whole, it was higher in meta search system using Open API of library online catalog than OPAC-based search system using Open API of library online catalog, and there was statistically significant difference. Therefore, if libraries share and use enriched content which is provided through Open API for book search, which is opened by Internet bookstores, search engines and Web portals, it is expected that it will be helpful in enhancing bibliographic data, expanding subject access point, empowering subject search ability, extending meta search service, improving book availability, and reducing catalog cost.

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 was to analyze and evaluate the characteristics of online catalogs' interface of children's libraries, and to propose how to design user-friendly interfaces. The online catalogs of 77 children's libraries which are registered on the National Library Statistics System as of December 2011 were analyzed. They are categorized into 7 types based on interface's characteristics. Such topics as the features of search methods, the record display formats, the terminology usage, and the special features of the 7 types were examined and discussed. Some shortcomings were examined and how to improve them was suggested.

This article proposed a new online union catalog of children's material owned by children's libraries and public libraries in Korea. In order to meet users' information needs about children's material the existing access points in the online catalogs should be expanded including such information as children's age, type of publication, genre, subject, theme, book review, awarded books, and location. Since location information about a particular material is essential to users, a national online union catalog of children's material should be constructed.

The purpose of this study is to identify users behavioral characteristics for using the online catalog opened in May 1996 at Duksung Women's University Library. 278 student users were surveyed from October 4th to 8th in 1996. Major findings are as follows. 1. Most users$(87.4\%)$ prefer the online catalog to the card catalog and regard the online catalog easy to use$(89.6\%)$ 2. $(65.8\%)$ of users are active users who frequently use the online catalog at least 10 times or more per semester. 3. $10.4\%$ of users feel the online catalog difficult because they do not know how to use it. 4. Most users prefer the menu search mode among menu, command and fill-in-blank search modes offered by DISCOVER. The most preferred access points are the title for known-item search and subject headings for subject search. 5. User's attitude toward the online catalog is very favorable$(83.5\%)$, however, the search success rate is rather low $(77.0\%)$ compared to that of the card catalog $(87.0\%)$ 6. The title and author are regarded easy to use among access points offered by DISCOVER. Classification numbers and call numbers are the least easy access points to use. 7. Since users show lack of knowledge of how to use the online catalog, education and training programs on the online catalog use for users are needed. 8. Users showed different search patterns for pursuing different search goals. The most preferred access points are the title for known-item search and subject headings for subject search. These search behaviors are different from those in using the card for both the known-item search and subject search was the title.

The primary questions addressed by this research are the followings: Has the interface of a Web-based OPAC been improved more user-friendly; How about its searching abilities; What difficulties have Web-based OPAC searchers experienced in using a Web OPAC; How do they perceive the system after use of it. Finding the answers of those questions the problems of a Web OPAC as a searching tool have been grasped and recommendations have been suggested in order to improve the system. An experiment was conducted and 30 university students performed 8 searching tasks. The searching behavior of Web OPAC searchers has been analyzed thoroughly. The data of their perceptions about the system was collected through a questionnaire after completing the tasks.

this study is to determine whether color, icon, sorting methods of brief description about materials, and postioning methods of final records affect the usability of the OPAC(Online Public Access Catalog) screen designs in terms of success rate, search time, and users' preferences. The findings suggest that OPAC systems can be optimized to enhance user's performances conflict with each other, designers should give more weight to performance because of the library's mission of meeting users' information needs.

As the rapid develoment of internet and information technology, the traditional library has been altered to the digital content service based on the world wide web. This paper proposes a design and implementation of an Artcle Union Catalog System(AUCS) based on metadata. The metadata set for the AUCS consists of twelve Dublin Core elements and one holdings element. The qualifiers of the proposed metadata elements are also represented. The AUCS system has an online cooperated cataloging system using the web interface or the 239.50 protocol, an union cataloging management system, and an integrated information retrieved system service. The integrated search and retrieval service of the AUCS displays not only the summary and detailed bibliographic information, but also the abstract, the table of contents, the digital content, and the copylfax service.
