People who have written a book can have it published by choosing a self book publishing company. This is an easier way to get a first book published than trying to go through regular publishing companies. The company offering this service will allow the author to submit any images used inside the book as well as the image for the cover. The self publishing companies will need to look at the manuscript and accept it before the process can begin. Like regular publishing companies, these places also have certain requirements and specific categories for the books they publish. The company will provide the ISBN number so the book can be sold.
