From Digital Book World:
Hybrid authors who self-published their last book did so because of the amount of creative control they retained, the ease of the publishing process and the amount of money they can make, according to a new report from Digital Book World and Writer’s Digest about the habits and preferences of hybrid authors. This early data from the report was presented by Phil Sexton, Writer’s Digest community leader, at the IDPF Digital Book 2013 conference in New York.
When hybrid authors who chose to self-publish their last book were asked why they chose to do so, nearly two-thirds said one of their reasons was that self-publishing helped them exert more creative control on the final product. Some 40% said one of their reasons was because the ease of the self-publishing process, and nearly 40% said it was because they could make more money self-publishing.
Hybrid authors who published their last book with a traditional publisher said they did so for completely different reasons: amount of help received along the way (half); total reach of distribution (nearly half); and the prestige of working with a large publisher and seeing their books on major bookstore shelves (about a third).
. . . .
For authors who would prefer to self-publish their next book, the top three reasons why are:
1. Amount of creative control retained (three-quarters)2. Amount of money that can be made (nearly 60%)
3. Ease with which the publishing process is completed (about a third)
