By default, iBooks Author creates lists for you automatically, when you type text that appears to be a list. For example, if you type a bullet (Option-8), a space, and text, iBooks Author automatically formats the next paragraph as a list by adding a bullet for you.
You can also turn a paragraph into a list and vice versa. You can format lists using the List pane of the Text inspector:
Format a list
In the Text inspector, click List.
Select the text you want to format.
You can select text you want to turn into a list or text already formatted as a list.
Choose a list type from the Bullets & Numbering pop-up menu.
Text Bullets: Choose one of the provided symbols or type your own character in the field.
You can also choose a special character and drag it to the field.
Image Bullets: Choose one of the provided symbols.
Custom Image: Use your own image as a bullet. To choose an image, click Choose or drag a new image to the field.
Numbers: Create a numbered list.
Tiered Numbers: Create a legal-style list (1, 1.1., 1.1.1, and so on).
Do any of the following:
Promote or demote an item in a list: Click an Indent Level button (in the List pane of the Text inspector) or choose Format > Text > Option.
Change the number that begins a numbered list: Select “Start at” and type the number.
Automatically increase or decrease a bullet’s size when you change the size of its text: Select “Scale with text.”
Change the distance between the margin and the bullet (or number): Use the Bullet Indent field or the Number Indent field.
Change the distance between the bullet (or number) and its text: Use the Text Indent field.

Press Return twice.
Turn automatic list generation on or off
Choose iBooks Author > Preferences, and click Auto-Correction.
Select or deselect “Automatically detect lists.”

You can also create a list style and add the new style to the Styles drawer.
