Children's book preparation before submitting to any publisher begins with a final draft of the book and a clear understanding of the age category your story is intended to appeal to, because there are particular requirements for picture books, early readers, and middle-grade stories. The pictures accompanying the text are just as important as the text itself, and many authors usually collaborate with illustrators beforehand, or submit the manuscript only and have the publisher provide illustrations. At the research stage, it is necessary to identify suitable publishers, examine their submission guidelines, and create a short synopsis along with some sample pages. Authors in Canada should find online children’s book publishing services in Canada to do so more easily.
