Well, he is right and he is wrong. Most of small publishers these days don't do promotoion, although they consider themselves 'publishers'. They edit the author's text (slightly), format it for Kindle and other e-readers, and set it up on their websites, Amazon, and other online booksellers. Then the autor has to promote and sell her book herself, and they just reap the percentage stipulated by their contract. I signed up with a small publisher lately for my first book and now I think maybe I've made a mistake. Maybe I should've self-published. Whatever I sell, I wouldn't have to share the income with them.
