First Networked Book?

Via Rachel Cunliffe of crea8d: Publishing’s first “networked book”–PULSE–came out today. Admirable concept and site design by Names@Work.

The book is simultaneously being published in book form and being serialized in its entirety on the site and via RSS.

Hypertext books have been around for a while, but this is the first instance I know of where a mainstream print publisher is taking this kind of plunge.
