"Bits of destruction" is a phrase Fred Wilson uses to describe the destructive part of "creative destruction" brought on by digitization. We hear a lot about the destruction wrought on the newspaper business. A more interesting and nuanced wave is now hitting the book publishing business. Actually, it is three waves: the digitization of back catalogs, e-books, and print on demand. However this plays out, a lot of people will be affected, but the way in which it will play out is not at all obvious. This is too big a subject for one post, so read this as an introduction to a multi-post investigation.
