O vazio da estante: o acesso ao livro digital sob a perspectiva das suas dimens es política e cultural

The purpose of this writing is to delineate a dissemblance of the digital book as an object of research in the field of media communication. To do so, it focuses, as a proposal of study, on the issue of supply and access to this media and also its circulation process. Thus, it arises with two dimensions, shown as complementary ones, when it is referring to the reach on digital books: political-communicative and culturalcommunicative dimensions. The first refers to aspects related to institutions involved in the formation of the universe of the commons and in the circumscription of intellectual property. The second concerns the cultural aspects implicated in the use of the digital book: symbolic values, changes in social practices, both informational and communicational, and cultural-historical mediation of the printed book.
