A reader writes to ask:

I'm preparing a manuscript for a children's book. Should I use the same format [as for adult fiction]? Or is there a different format for this type of book?

Yes, when submitting a picture book, chapter book, or other work of children's literature, you should use the same format you would when submitting any other book manuscript. If the book is to be illustrated, your publisher will most likely recruit the illustrator for you.

For much more detail about the kinds of children's books out there and how to sell them, consult a book like The Complete Idiot's Guide to Publishing Children's Books. It will have far more useful information on this segment of the publishing business than I can provide.
