The notion of real publishing as opposed to self-publishing and the stigma surrounding it is obsolete. I have no objections to traditional publishers but every one of them started off as a “self-publisher” with a first book. I have pretty much stopped referring to myself as a “self-publisher.” I produce and market books like anyone else in the business.
Real Publishing vs. Vanity Publishing: Self-publishing is often confused with so-called “vanity publishing.” If you pay someone like XLibris or iUniverse to publish you, you are not a publisher—and neither is the company that claims to be your publisher. Vanity presses take zero risk on your book. They make money producing it and they take a piece of the cover price as a royalty, double-dipping at your expense. If your so-called publisher has not made an investment in your work, they are not a real publisher. Real publishers invest in books, pay royalties when there are profits and incur losses when sales don’t match projections.
