Everything about the book seems to have changed because of the web. The new book is the ebook, the new book shop is Amazon, the new form of the book is the iPad or the Kindle. These already appear to be big changes but there is much more to it than that.
Marshall McLuhan puts it like this "We're just trying to fit the old things into the new form instead of asking what is the new form going to do to all the assumptions we had before."1
To understand the new world of the book we must challenge our assumptions about the book. We must understand that web changes not only the format of the media and the available distribution channels, but the cultural context, economic and social processes surrounding the book. Most importantly, the web changes the reasons why books exist and your relationship to the production of knowledge and culture.
These seismic changes are occurring because a webpage is a book or rather, a book is just a webpage.
