Reading Images: Multimodality, representation and new media

In this paper I wish to point to what I see as the central issues in the linked shifts in representation and dissemination: that is, from the constellation of mode of writing and medium of book/page, to the constellation of mode of image and medium of screen. In particular I will draw attention to consequent shifts in authority, in changes in forms of reading, shifts in shapes of knowledge and in forms of human engagement with the social and natural world.
