Number of pages
I understand the maximum number of pages for a 6x9 hardcover book is 800 pages. Now is that just the book itself, or does it also include the small title page, large title page and author's name, the copyright page, and the dedication page? My novel is currently 799 pages, and that is just the novel without all the preliminary material.
