USIT
By creating linked information spaces on the Internet, opportunities exist to create local, regional and national information highways, spanning across communities interacting within themselves, or with other regions. By linking together citizens, schools, libraries, newspapers and other information sources, local authorities and institutions, and with outside connections, it is possible to create powerful regional electronic infrastructures.
