Discovery is an emerging concept to enhance the search capabilities of library resources with the Next Generation Library Catalog. This paper defined the Discovery feature based on the information search behavior, and then derived the elements that make up its function. After that, the 11 regional representatives libraries' OPACs and 3 Internet bookstores are evaluated and compared against Search & Discovery capabilities. As a result, the Internet bookstores were superior to the libraries' OPACs for all the elements that make up the Discovery functions. This study verified that the public libraries OPACs are still concentrating on known item search, and it is hard for the users to meet a serendipity which is gained through the Discovery functions.

정보검색과정에서 온라인 시소러스는 이용자가 생각하고 있는 개념어를 시스템의 색인어로 보다 정확하게 표현하는 동시에, 관련구조를 통해 탐색의 범위를 확장ㆍ축소할 수 있게 한다. 온라인 시소러스를 충분히 활용하기 위해서는 이용자가 시소러스의 구조에 쉽게 접근하여 계층ㆍ관련구조를 충분히 살피고, 용어 사이를 자유롭게 탐험할 수 있는 장치가 필요하다. 본 연구에서는 기존의 시소러스 표시방법의 장단점 등에 근거하여 정보검색과정에서 이용할 수 있는 시소러스 브라우저를 사전탐색 기능, 시소러스 구조의 표시 기능, 탐색문 형성 기능으로 나누어 설계하였다.

This study identified types of information source, and explored a path model for consumer information search by shopping attributes in the context of online decision making. Participants completed self-administered questionnaires during regularly scheduled classes. A total of 219 usable questionnaires were obtained from respondents who enroll at universities in the southwestern region of the United States. For data analysis, factor analysis and path model estimation were used. Consumer information source was classified into three types for online clothing purchases: Online source, Offline retail source, and Mass media. Consumers were more likely to rely on offline retail source for online clothing purchases, than other sources. In consumer information search by shopping attributes, online sources were more likely to be related to transaction-related attributes(e.g., incentive service), whereas offline retail source(e.g., displays in stores, manufacturer's catalogs and pamphlets) were more likely to be related to product and market related attributes(e.g., aesthetics, price) when purchasing clothing online. Also, the path model emphasizes the effect of shopping attributes on traditional retailer search behavior, leading to online purchase intention for clothing. This study supports consumer information search by attributes, and discusses a managerial implication of multi-channel retailing for apparel.

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.

The study aims at understanding that the precedent information search Patterns of on-line database users compared to non-users have an effect on user satisfaction. The research team analyzed S college students' library system use patterns to evaluate the efficiency of library information services and systems and therefore to diverse factors to improve user satisfaction. The research showed higher satisfaction from on-line system users than non-users. To satisfy user needs the research recommends more devices access methods to information.

The purpose of this study is to verify the difference of behavioral characteristics between the primary and secondary search, the influence of the primary search results on Online databases. Data is collected by surveying the professional and end-user searchers in 33 online information service centers. 262 valid responses out of 308 questionaire are analyzed by the t-test, ANOVA, $\chi^2-test$ using SAS program. The major findings are as follows : (1) Preparatory searches(the levels of expectation, the degree of question comprehension), search results(the number of output documents, precision ratio, recall ratio, degree of satisfaction) are significantly different between the primary and secondary searches on Online Databases. But the number of search terms, Boolean logics, files, systems, relevant documents are not significantly different between the primary and secondary searches. (2) The results of the primary search affect the secondary searches. The number of output documents in the primary search affect the modification of search strategies and objects in the secondary searches. The number of relevant documents affect the variation of search scopes in the secondary searches. The precision ratio affect the change of search strategies and scopes in the secondary searches.

The purpose of the study is to identify what search options are used to decide how to search on the online catalog system, and to suggest a format of the initial screen NOTIS and Dynix systems were used. Data collection was conducted in accordance with a $'2\times2'$ design. The study shows the effect on user choices of the initial men formal especially where the arrangement and breadth of search options are concerned. The availability of search options provides various users' search option selection The results of the study suggest that users can input only search term(s) on the initial screen without choice of search option Then, users may select search fields depending upon the results of searching. This method can reduce the search fail when users select wrong search option on the online catalog.
