Book review: Gerbault, Jeannine (eds.). 2007. La langue du cyberespace : de la diversite aux normes. Paris : L’Harmattan. ISBN : 978-2-296-04622-1. Today, communication through language takes place in a place, cyberspace. New communication tools are emerging, language practices are appearing and covering multiple realities. Email, forums, blogs or sms become common modes of communication. Communication mediated by information and communication (CMT) includes, in addition to the computer, other tools, especially those that rely on the mobile phone. The changes brought about by these new technologies have transformed the panorama for all the actors of the communication. Indeed, the content continues to be conveyed by the language beyond the tools and devices deployed, and the cmt gives rise to linguistic and social changes that can not escape us, raising questions; these changes have changed the areas of research of language specialists as well as those of communication specialists.
