Authors, Writers, Publishers, and Book Readers

On my blog, Davenportwrites.com if you search publish or self publish in the search you'll find a lot of topics regarding this same debate. In the end, I'm a firm believer that neither needs to exclude the other. I currently run a Booking and Promotional agency for Iowa Local Authors, and most of my authors have a combination of self-published and traditional titles. The confusion is that people seem to think that the author has to be self-published or traditional, those are conditions for books, not authors, and should be considered on a book by book basis. I've normally gone self-publishing on each of my books just because it's quicker, but that's still something I evaluate regularly.
On that subject, I have spoken at length, including in my most recent title: Self-Publish Without Spending Money. It focuses on the path from finished first draft to cover creation, edits, and marketing/selling your work, while also spending time on the pros and cons of traditional vs. self-publishing. I encourage you to check it out.
