Controlling page numbers
If your chapters have sections (Page > Section) when you add them to a book, the sections and page numbers are maintained. For example, each chapter in a book might be a new section. If your chapters do not have sections, QuarkXPress assigns sequential page numbers to the chapters in a book. For example, if the first chapter in a book is 10 pages long, the second chapter starts on page 11.
You can add and remove sections to change the page numbering of a book. If a document page has an automatic page number character on it, that page will display the appropriate page number.
