Books are not just “tree flakes encased in dead cow”, as a scholar once wryly put it. They are a technology in their own right, one developed and used for the refinement and advancement of thought. And this technology is a powerful, long-lived and adaptable one.
Books will likely continue to become more interactive, so authors need to develop some new media skillsets. When publishers develop apps so readers can do things like post selfies with authors within the author’s e-book, there will be more ways to generate interest and sales.
