Publishing: A whole new chapter? - Chicago Tribune: "A futurist author could help direct the publishing future. David Houle, author of “Entering the Shift Age,” is participating with Naperville-based Sourcebooks Inc. in an initiative that could redefine the definition of a book and how books are published. Sourcebooks refers to it as its “agile publishing model,” which seeks to hasten the publishing process, to shape a book's content as it's being written through feedback from an interactive community of readers and to nurture branding by releasing advance segments of the book in progress. Houle's book will be the first published under the Sourcebooks initiative — among at least a few innovative and interactive approaches that writers and publishers are attempting to further bring the market into the 21st century."
