This paper traces the growth of the Internet and knowledge networks in the world, with an explanation of the implications of the Internet for the developing world. Starting with a brief history of the development of the Internet, the paper describes the phenomenal growth of Internet networks and how the uses made of the Internet have evolved tremendously in the last fifteen years. The potential of the Internet has not been fully realized in many developing countries due to a variety of factors. Therefore there is a unique opportunity for libraries and librarians to lead the movement to increase access to information for citizens of developing countries, through using the powers of the Internet adapted to the conditions in each country.
