Viikki is one of the four campuses of the University of Helsinki. The Viikki Virtual Infocenter will be located on the Viikki Campus in Helsinki. It will be a modern learning environment that offers library and information services, study rooms and learning facilities, computer and network services, and administrative campus services to students and researchers. A good guiding system and a clear user interface are essential for the effective use of all these services. Clients will need guidance in the navigation, both in the physical building and in the huge information cyberspace. The Viikki Virtual Infocenter will consist of two interlinked parts: the guiding system of the building and the user interface to the library's networked resources providing users with easy access to a range of systems and services. The Virtual Infocenter integrates electronic information services into a broader electronic learning environment and functions as a facilitator in an information landscape. The Viikki Virtual Infocenter will be available in Finnish, English, and Swedish. This paper describes the electronic guiding system and discusses the challenges and rewards in the development of the virtual learning environment. (AEF)
