For best results, be sure to do the following before creating a table of contents for a book:

• Before you create a table of contents, verify that the book list is complete, that all documents are listed in the correct order, and that all headings have been formatted with the appropriate paragraph styles.

• Be sure to use paragraph styles consistently throughout the book. Avoid creating documents with styles that have identical names but different definitions. If multiple styles have the same name but different style definitions, InDesign uses the style definition in the current document (if a definition exists there), or the first occurrence of the style in the book.

• If the necessary styles do not appear in the pop‑up menus in the Table of Contents dialog box, you may need to synchronize the book so that the styles are copied to the document containing the table of contents.
