"Above all, the translation of books into digital formats means the destruction of boundaries. Bound, printed texts are discrete objects: immutable, individual, lendable, cut off from the world. Once the words of a book appear onscreen, they are no longer simply themselves; they have become a part of something else. They now occupy the same space not only as every other digital text, but as every other medium too. Music, film, newspapers, blogs, videogames—it’s the nature of a digital society that all these come at us in parallel, through the same channels, consumed simultaneously or in seamless sequence."
