Navigare necesse est, vivere non est necesse - suggested the portuguese poet Fernando Pessoa. In the beginning of the 21st century to navigate is a powerful verb, since we all navigate on the internet. At a click - sites come and go in our screens. This dissertation intends to investigate how autorship develops in contemporary times, in the face of the birth of new media. We intend to analyze two phenomena: the first one would be a decentralisation of authorship through the publishing of shared writing in blogs and the interference of the publishing market in the process of writing, with suggestions of themes, formats or procedures that used to be in authors hands in the past. This phenomenon demonstrates the progressive profissionalization of the author. The second one - apparently opposed to the first one - refers to what we might call the strenght of the author s image, especially in cyberspace, that has lead to a kind of resurrection of the author. This phenomena contributes towards the creation of an author s persona in cyberspace, where everything seems to be imprecise, since a single arena - the computer screen - is the place where both fictional and non-fictional communication takes place. Therefore, we intend to investigate the author s presence in two fields: cyberspace, through their participation and work on internet, and in real life, through their participation in literary events and interviews. What is an author? Michel Foucault asked back in the 60s, and his question remains relevant in the volatility of our cyber times.
