Information Networks 

Information networks in the broadest sense can be any formalised system of information exchange. But, in modern information networks, technology is utilised to link libraries, specialised data resources, or individuals to the persons or institutions in need of information. It was not until 1960s, however, that libraries could be linked by telecommunication to central computer facilities built around a bibliographic data base. From this developed a network structure that made new technology available to libraries across the country (Penniman, 1976).
