The book explores the nature of Web communication in terms of hypertextuality, hypermodality and hypersemiotics. It starts by investigating the net-shaped and multi-coded architecture of information translated into English Web discourse practices. It shows how linking mechanisms, embedded in a hypermodal domain, become both cognitive potential and rhetorical devices, and participate in the meaning-making process. The hypertext dimension of the Internet and the technologies involved have thus given origin to other forms of textuality that require a different framework of analysis. The study focuses on the nature of these new genres present on the Web.
