In 1992, three years after the commercial restrictions were lifted on what then became the Internet, and just a year after the development of the World Wide Web, I published the book Contexts of Computer-Mediated Communication, which introduced a new approach, based on the concept of social identity, to studying people's online communication, relationships and behaviour in interpersonal, group and organizational contexts. The book challenged the orthodoxy of opinion regarding the new forms of communication that had emerged, and since publication has been cited in over two thousand articles and books. I have also contributed to more than 20 other books in the field. You can read and download my contributions to some of these titles below.
