On the whole, the virtual libraries have responded succesfully to users data search needs. 91.7 per cent of the respondents who had evaluated a virtual library close to their own field of science intended to use the library again. The project has plans e.g. to develop the essence of virtual libraries and the information services offered by them, to test various database solutions and to construct virtual libraries in new fields. The future role of libraries will include continuous evaluation of information resources on the net. A central task area is also to guide people in the use of networks and to make the use of networks as easy as possible.
Virtual libraries are one way the libraries can answer future challenges.
