Like a search engine, the cyberspace is seen as new semiotic machine, which brings about new writing agencies and knowledge organization. In this sense, the new theoretical and practical aspects of the knowledge organization in cyberspace are discussed. This process, made by indexing services and search engines, confirms that there is no general syntax, neither any universal or dichotomy system of knowledge classification/cataloguing. This is because the virtual environment operates the multiplicity and the "deterritorialization" of signs, making impossible the physic and semantic closing of works.
