When a book is in scrolling view, readers can scroll continuously through it instead of swiping to turn each page. Scrolling view is always available in EPUB templates, and you can enable or disable it in a landscape template.
To allow readers to switch to scrolling view in a book created with a landscape template, click the Inspector button
in the toolbar, click the Document inspector button
at the top of the inspector, then make sure “Disable scrolling view” isn’t selected.
To switch to or from scrolling view in the completed book, readers tap or click the Fonts button in the top-right corner of the Apple Books window, then tap or click Scrolling View.

To switch to or from scrolling view while working on a book in a landscape template, click the Scroll button
in the toolbar. (EPUB templates always appear in scrolling view as you work.)
Note: In books created with a portrait template, the view is always paginated—you can’t scroll through the content.
