A contents template allows you to specify information that is relevant to all sections (or most of the sections) when you register a new book (this is useful if, for example, the book contains multiple sections written by the same author). The information you specify is automatically used when you add new sections. You can also save a template to a file and reuse it later.

If you always want to use a contents template when you add new sections to a book, select the 'Use contents template' option under Tools->Options.

You can also use a contents template to register information after all sections are added to the book. For example, if you only specified titles when you originally registered the book, you can assign a contents template to the sections in the book at a later time. This allows you to register information for all sections in the book in one operation.
