The title and name you enter on the front cover of your book will automatically appear on the spine of your hardcover book. And if you have more than 80 pages in your book, this applies to softcover spines as well.
If you would like to change the text on your spine, navigate to your cover layouts and click on the spine’s text container. Type inside the text containers to update any text on the spine.
If you change the spine’s text so that it no longer matches the title or author name on your front cover, you’ll be asked to unlock the text area of the book spine to make that change.
Modifications to the book’s spine will not affect the text on the front cover.
