When a site makes use of the Drupal core Book module, one of the features of this module is the automatic display of navigational items that appear on the bottom of the book page.

For all book pages a "Previous, Next, and Up" navigation feature is included, which allows the audience to easily navigate through pages and sections of the book.

From this point on, the automated book navigation at the bottom of the book page content will not display.
