The study was undertaken to explore the extent of Utilization of Internet among library and information science academics in the provision of library services and for educating prospective librarians in academic departments in Nigerian universities. Investigation was carried out in respect of the type of Internet services available, the various uses, preferences in the use of Internet, satisfaction with the use and provision of Internet facilities and the factors influencing use. The paucity of studies on Internet use in general necessitated this study. Using six research questions and three research hypotheses, data was collected from 198 academic librarians and library and information science lecturers in 7 universities with Internet in their library science department and/or their libraries. The data was treated using frequency distribution tables, percentages and mean scores while the hypotheses were tested using t-test statistics. The results show among others that Internet use by the studied academics is useful for their information needs and that Internet search services are preferred above Information retrieval services, communication services and multimedia services. It also shows that there are some barriers to adequate use of Internet resources. Suggestions are made for increased use of the Internet to benefit the nation as a whole.
