This paper describes recent developments and trends of digital reference services. A brief overview of selected research on issues surrounding digital reference service is provided. It also discusses how technological developments in libraries have led to the emergence of new service paradigms. This paper briefly reviews reference and information services provided by libraries, those from publishers, those provided by experts, and those where users need to conduct a search and find information through the web. The current trend shows that the cooperative model is increasingly popular. Some projects on collaborative digital reference services(CDRS) are introduced. Librarians will need to continue analyzing the need for cooperative work in the reference service in a digital environment.

The purpose of this study is to develop a practical model for enhancing cooperative virtual reference services of public libraries in the nation. The research methods include an examination of model cases from Europe and the V.S. and also an electronic questionnaire survey of 375 public librarians (73% response rate). The study results suggest the need for 'a collaborative virtual reference room' which consists of the collaborative reference database, virtual reference desk, guidance and instruction designed by age groups and/or subjects.

This paper aims to seek ways of optimizing the operations of Collaborative Digital Reference Service(CDRS) in Korea. CDRS tries to specialize the reference service through world-wide collaborative service. In this study seven international CDRS services including "QuestionPoint" operated by ALA and one national service, "Ask a Librarian" by the National Library of Korea were surveyed. A focused analysis of CDRS in Korea shows not only a sharp increase in use by the public, but also much application in research and academic activities by university students and workers.

This study was conducted to investigate the materials deposit policies and service policies of overseas collaborative repositories and provide practical data that can be referred to the management of the collaborative repository in Korea. For this purpose, this study tried to analyzed websites of 7 collaborative repositories and related data. Materials deposit policies were focused on duplicate materials, criteria of materials to be accepted, ownership and withdrawal and service policies were focused on on-site services and off-site services including circulation and document delivery service(electronic copy and photocopy). The results of this study can be used as practical data for the establishment of guidelines for collaborative repository in Korea.

The purposes of this article are to raise the quality issues of Collaborative Digital Reference Services(CDRS) in Korean libraries and to suggest the feasible solutions to resolve the quality problems of CDRS. To the end, a thorough examination on the development process and present condition of main Korean CDRS such as 'Question포인트' and' '사서에게 물어보세요'. This article investigates the causes of 'low quality' in Korean CDRS with emphasizing both technical problems and managerial limitations. Finally suggested are the solutions to improve the low quality of CDRS with special concerns on Korean library situation. Discussions on this article are based on literature review, statistical analysis, and usability tests on the targeted Korean CDRS, '사서에게 물어보세요'(Ask a Librarian in Korean version).

Although it is about a decade since public libraries started to provide digital information services, lack of expertise for efficient service operation and restrictions related to copyrights have led to failure to obtain remarkable performances in uses. This study intends to analyze operation cases of domestic and overseas collaborative digital information services, as well as the current status of digital information services of libraries in Gyeonggido, thereby developing a collaborative digital information service model among public libraries on the level of local governments. This research then analyzed collaborative digital information service Web sites and surveys. Based on the analysis result, this study presented support of integrated search of possessed electronic information, Web database (DB), DB on original texts of regional records, online reference services, and mobile platforms as functional factors to embody a successful service model. As a system management road map, an eclectic model combining the merits of centralized and decentralized models was found to be more effective than a centralized or decentralized model in consideration of the characteristics of participating organizations.

Most of the university libraries in Korea provide digital reference service(DRS), but the use of DRS is very low. The low usage of DRS seems to result from the lack of subject librarians, of staff, of public relations, and of managers' enthusiastic attitude and understanding of DRS. It is difficult to solve these problems because of the poor circumstances in universities. The collaborative digital reference service(CDRS) is a solution to these problems. Not only CDRS costs little but also can provide reference services in many different subject areas. Though subject specialist librarian, user-friendly system interface, system programs and administrative supports are necessary to implement CDRS, the education and training of the subject specialist librarians is the most important work to be done in the university library situation in Korea.

Recommendation is to offer information which fits user's interests and tastes to provide better services and to reduce information overload. It recently draws attention upon Internet users and information providers. The collaborative filtering is one of the widely used methods for recommendation. It recommends an item to a user based on the reference users' preferences for the target item or the target user's preferences for the reference items. In this paper, we propose a neural network based collaborative filtering method. Our method builds a model by learning correlation between users or items using a multi-layer perceptron. We also investigate integration of diverse information to solve the sparsity problem and selecting the reference users or items based on similarity to improve performance. We finally demonstrate that our method outperforms the existing methods through experiments using the EachMovie data.

Because of the increased interest in health, medical care, and wellness, the utilization of health-related information resources, especially those found on the Internet, has been rapidly increasing. In addition, despite encountering an increasing number of health and medical-related reference questions in public libraries, public librarians feel limitations in their ability to perform these types of reference services. Therefore, this study proposed the cooperative network system model for vitalizing CHI Services, meaning that all the related agencies, including public libraries, medical libraries, medical institutions, and the health and medical community collaboratively provide consumer health information service. This study presented in detail the key elements of the cooperation model, the subject of cooperation, target sources for cooperation, the content of cooperation, operations of CHI-providing sites, operations and roles of Cooperation Centers, and directions for cooperating with commercial institutions.

The author analyses the challenging activities of Japanese libraries in this decade by launching two keywords; "product-sharing" and "outcome generation." "Product-sharing" means that libraries share knowledge, skills, and records which are produced as the result of the services or in the process of activities. And "outcome generation" means that libraries generate any efficiency or effectiveness through their services to users. Using these concepts, reported are the current situation and aspects of Japanese libraries which try to make various contributions to the society; research and learning of the people, and education and training for professional librarians, and so on. In the analysis, the author shows some examples of "product-sharing" at first, including the records of reference transaction and the multi-functioned online public access catalogue. Especially, focused is on the various possibility and adoptability of the Collaborative Reference Database System of the National Diet Library of Japan. This system is one of digital reference service in Japan, and the database of reference transaction records is expected to be useful for research and academic studyies as knowledge-base of professional librarians. And the system is also expected to be a platform for LIS education and professional development in the e-learning environment. Secondly, as the examples of "outcome generation", explained are the problem-solving-type activities, and provision of the collection about books on struggling against disease and illness. A few examples of outcome in the problem-solving-type activities are these; increase of sales in the services for shop managers, business persons, and entrepreneurs, contribution to affluent daily life by providing the local information services to residents and neighbourhoods, and etc. And for both the patients with serious cases and their family or those who nurse them, books about other persons' notes or memorandum are the greatest support, and sometime healing. The author discuss the 'raison d'etre' of these activities focusing on public libraries in Japan.
