The economics of digital books will likely change the conventions of reading and writing as well. Digital distribution makes it a simple matter to offer prospective buyers a "free sample" to entice them to purchase the whole thing. Many books offered for the Kindle, for instance, allow readers to download the first chapter free of charge. The "free sample" component of a book will become as conventional as jacket-flap copy and blurbs; authors will devise a host of stylistic and commercial techniques in crafting these giveaway sections, just as Dickens mastered the cliffhanger device almost two centuries before.
It's not hard to imagine, for instance, how introductions will be transformed in this new world. Right now, introductions are written with the assumption that people have already bought the book. That won't be the case in the future, when the introduction is given away. It will, no doubt, be written more to entice readers to buy the whole book.
Clearly, we are in store for the return of the cliffhanger.
For nonfiction and short-story collections, a la carte pricing will emerge, as it has in the marketplace for digital music. Readers will have the option to purchase a chapter for 99 cents, the same way they now buy an individual song on iTunes. The marketplace will start to reward modular books that can be intelligibly split into standalone chapters.
This fragmentation sounds unnerving -- yet another blow to the deep-focus linearity of the print-book tradition. Breaking the book into detachable parts may sell more books, but there are certain kinds of experiences and arguments that can only be conveyed by the steady, directed immersion that a 400-page book gives you. A playlist of the best chapters from "Middlemarch," "Gravity's Rainbow" and "Beloved" will never work the way a playlist of songs culled from different albums does today.
