In this text, Herring brings together a variety of sociological and linguistic essays on computer-mediated communications.  In the first section, "Linguistics Perspectives", the authors seek to define the oral and written linguistics aspects of email, IRC chat, and computer conferencing while contrasting them with face-to-face interactions.  In the second section, "Social and Ethical Perspectives", the authors deal with social issues of interaction such as cooperation versus conflict and the role of radical feminism for internet discourse ("Cyberfeminism" by Kira Hall).  The third portion deals with "Cross Cultural Perspectives" in which CMC is analysed between North American, East Asian, and Mexican students and theories of classroom diversity are presented.  Finally, the last grouping "CMS and Group Interaction" explores how CMC can change people's lives - exploring the group dynamics of online forums (Korenman and Wyatt, "Group Dynamics in an Email Forum"), how e-mail has changed the work environment, and how groups conduct internet-based protests.
