This paper shows how often the traditional publishing is useless for scientific research because scholastic materials should be available for the scientific community as soon as possible. In fact, we must consider that many documents, such as pre-print, grey-literature, reports, meeting papers, documents pre- or post- edition, are useful materials for growing of any subjects. Nowadays, for scientific studying the immediately available of these kinds of documents is a main need. Moreover, with the WWW and specific software for managing of e-prints is possible building an Open Archive of electronic documents. Consequently, it will be possible that research workers all over the world may read and obtain the most recent result of research realized, as a free format.
