No, hybrid publishing is not self-publishing. Hybrid publishing is a new model of publishing that combines the best aspects of traditional publishing with the best aspects of self-publishing.
In traditional publishing, authors give up some control over their work in order to have it edited, designed, and marketed by professionals. This model often requires an author to find an agent, who then finds a publisher willing to invest in the book. In return for this investment, the publisher takes the vast majority of the profits from book sales.
In self-publishing, authors retain complete control over their work, but must invest their own time and money into editing, design, and marketing. Because they are investing their own resources, self-published authors keep a larger portion of the proceeds from book sales.
Hybrid publishing offers authors the best of both worlds: the professional editing, design, and marketing of traditional publishing, combined with the higher royalties and greater control of self-publishing. In hybrid publishing, authors work with a professional publisher to produce their book. The publisher invests in the book, and in return takes a smaller portion of the proceeds from sales. This arrangement allows authors to retain control over their work while still getting the benefit of professional help in making their book the best it can be.
