This paper focuses on the changes taking place in the behavior of those engaged in research and teaching as a result of the increasing availability of source material on the Internet. It first discusses who customers are and what they are using information sources for. It then looks at the range of new services that are on offer, and reviews a number of pieces of research which provide evidence for the way users are adapting to the Internet as an information resource. The report discusses "ingentaJournals," a database with over 1000 journal titles mounted and available to subscribers. The paper concludes that there is an increasing need for ongoing research into how user behavior is changing as new services and new opportunities for changed methods of research and working evolve.
