Abstract

The extraordinary capacity of computers to hold text is familiar to anyone who uses a word processor: an average book will fit comfortably onto a 3.5" floppy disc. With the growth of easy means of communication between computers an immense quantity of information has become available on a world-wide basis. The links may not yet amount to a "superhighway", but they are fast, efficient and increasingly user-friendly. Moreover, like the roads, the system is free to users (though the Clinton administration has made some ominous noises about introducing charges). It is open to anyone with access to a computer connected to JANET (the Joint Academic Network in Britain), INTERNET, or one of the other electronic communications networks that now span the globe. That means almost everyone teaching at an institution of Higher Education in this country, often including postgraduate students, and sometimes undergraduates as well. The material available on-line falls into three broad categories.
