Today we are preparing to accept the ubiquitous library age. This article will serve to define the concepts of the hybrid library, the gateway library and the ubiquitous library which hold the advanced concepts of the digital library. It will review the main projects about them in order to portray what the future libraries will be like and how they can be developed. In particular, the eLib program of the hybrid library, the gateway projects by Harvard University and Penn State University, and the ubiquitous library projects in Carnegie Melon University and Maryland University will be surveyed, through which the characteristics of the information services being operated by the ubiquitous libraries will be scanned.

A hybrid information environment can be described as one where an appropriate range of heterogeneous information services is presented to the user in a consistent and integrated way via a single interface. The purpose of this study is to suggest a need of hybrid information services through understanding of the hybrid information environment and hybrid library. Additionally, this study deal with basic concepts of design for a hybrid information service model and address a number of hybrid library projects based on these concepts, such as Agora, BUILDER, HealdLine, HyLife, and MALIBU. Finally, this study survey generic a model of hybrid library and suggest basic principles for building of hybrid information service model, such as integration, seamlessness, authentication, interconnectivity, and personalization of information seeking process environment.

National Union Catalog presupposes an information infrastructure which permits users to identify and locate materials of all the domestic libraries and to share materials among libraries. Recently, there have been developed national union catalog projects in many countries using Z39.50 protocol implementation. In Korea, multi-union catalogs based on the types of libraries, i.e., public, academic, and special libraries, have been constructed separately. The virtual national union catalog which is a decentralized electronically accessible catalog unified by linking the databases of several institutions using Z39.50 is preferable to a union catalog implemented by a single centralized database. In this paper, hybrid union catalog is suggested with mixtures of centralized union catalogs and Z39.50-based distributed search systems for the development of a national union catalog. It is also suggested that the roles of a national library and centers for union catalog, and relationships between two types of institution for making sound ground for implementing the virtual Korean union catalog.
