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.

This study aims to explore the status of next generation OPAC functionalities adopted by Korean academic libraries, and factors affecting their functionalities adoption. So 181 OPACs among 191 Korean academic libraries' OPACs are surveyed using a checklist consisting of 27 next generation OPAC functionalities. The relationships between the next generation OPAC functionalities adopted by academic libraries' OPAC and 6 factors of library, i.e., establishment, region of universities, volumes in library collection, total library expenditures, total target users, and automation solutions are analyzed by using SPSS Statistics 21. It is found that all factors except establishment of universities significantly affected the adoption of the next generation OPAC functionalities, and further detailed analysis for each factors is provided.

The purpose of this study is to provide an actual basic data and helps for arranging the next generation OPAC's interface and function through improving the existing OPAC's interface and improvement in the domestic library. In this study, factors to be importantly considered for improving the OPAC's interface and function were examined based on the preceding studies on OPAC concept & development process, user's library use style, user use style of OPAC, and recognition on library's crisis, and actual condition investigation result. Also, the case analysis on the existing OPAC's interface and function was focused on the search window, search item, search method, alignment function, search result display and search result feedback. Also, the search interface and search function of the next generation OPAC which is provided by the recently-developed domestic and foreign library utilization, and the detailed case were analyzed in the aspect of Library 2.0 service. Finally, the measures for improving the existing OPAC's interface and function in domestic library were suggested.

The purpose of this study is to analyze the characteristics of OPAC displays and search interfaces for children. The OPACS of Cheongju Miracle Library, Nowon Children's Library in Seoul. Los Angeles Public Library in the U.S.A. and HelMet Library System in Finland are examined on the basis of 'OPAC Display Guidelines(Draft)' published by IFLA and Nielsen's 'User Interface Design Heuristics'. Discussed are such topics as the features of basic and detailed search screens. the brief display of search results. the arrangement and full display of bibliographic records, and the displays for zero-results and large retrieval sets. The OPAC displays of Cheongju Miracle Library and Nowon Children' Library are not particularly designed to serve children which are their primary users. The OPAC displays for children of LAPL and HelMet Library System are rather simplified and customized to represent specifically the needs and information seeking behavior of children.

University library users prefer the internet to OPAC, when they search for information. It is necessary to develop interface of OPAC that is nearly as convenient as the internet. This study provides users with University Library Toolbar which is one of the ways to implement Web 2.0, and proved that OPAC is also a convenient and useful searching tool by offering the toolbar. In addition, the causes of the preferences of the internet sites surveyed for this study and the point shown in the comparison between the internet and OPAC are going to be essential materials to implement more convenient OPAC and Library 2.0.

This study aims to explore the status and adoption pattern of next generation OPAC functionalities employed in Korean academic libraries. The paper is useful for future planning of next generation OPAC in academic libraries. This study firstly extracted major functionalities of next generation OPAC by reviewing literature and then the pilot test was conducted to validate them. The websites of 191 academic libraries in Korea were surveyed. For the accuracy of the data, the two researchers examined in redundant. The collected data were analyzed using PASW Statistics 18. 'Simple search box' was found to be the most popular function. The second popular function was 'search within results'. A few libraries used the 'clustering', 'open search plug-in', 'sort by relevance', and 'correct spelling error'.

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.
