I am more of a computer science student/scholar but got started with books on Internet studies in the 76.9 range and the social impact of computers books. So I am recommending a textbook from computer ethics. I would also recommend giving students technical internet publishing skills by having a secondary book on HTML or CSS or other technical writing. This is so that students can be productive with the Internet as I imagine much future communications your students do will involve web publishing. Ian Graham has written for Wiley on HTML writing. His tutorials on HTML at the University of Toronto's web space could be used by those students who can not buy the second book. Here is a book from the 76.9 range Author Rosenberg, Richard S. Title The social impact of computers / Richard S. Rosenberg. Publisher Amsterdam ; Boston : Elsevier Academic Press, c2004. Edition 3rd ed.
