Writer provides a fast and convenient way to add one or more title pages to a document and optionally to restart the page number at 1 for the body of the document.
To begin, choose Format > Title Page from the Menu bar. On the Title Page dialog, you can make the following choices:
• Convert existing pages to title pages, or insert new title pages.
• How many pages to convert or insert.
• Where those pages are located.
• If and where to restart page numbering, and what number to start with.
• What page style to use for the title page.
Using this technique, you can insert several “title pages” at different points in your document, for example to add decorative pages between chapters as well as title, copyright, and other pages at the beginning of a book.
