How to Write a
Children's Book and Get It Published
by Barbara Seuling
I wrote my first book using this as a guide, and I still keep it handy when I'm putting together a manuscript. Barbara does a great job of explaining every part of the process, and her tips on preparing a dummy book are especially helpful. When people ask me how to get started in the field, I usually send them here first.
