How to Use Book Parts

Book parts let you categorize your book into subsections. They’re perfect for multi-part novels, anthologies, or any book that benefits from grouping chapters together.

What Are Book Parts?

A book part is a divider that groups related sections together. When you create a book part, all sections below it belong to that part until the next book part begins.

Table of Contents

When you use book parts, all sections within a part are indented in your table of contents. You can customize how book parts appear in your TOC, including typography and spacing, in the book part settings.

Creating a Book Part

1. Select the sections you want in the book part from the sidebar menu
2. Right-click the selected sections
3. Click “Create part from selected sections”

Book Part Rendering Options

When you create a book part, you can choose from four rendering styles:

Lacuna Default

A styled part page similar to the title page. You can control:

• Part number typography — Font, size, and styling for “Part One”
• Part name typography — Font, size, and styling for your part title
• Spacing — Control the layout and positioning

Full Page Image

Use an image as your part divider. This works exactly like a full page image section with the same settings and options.

Custom Content

A fully editable section where you can add any content you want. This works like a normal section, giving you complete control over what appears on your part page.

No Page

A grouping-only option that doesn’t render a visible page. This allows you to organize sections in your table of contents without adding a physical part page to your book.

When to Use No Page

Choose this option when you want table of contents subsections without changing the actual flow of your book. Your readers will see the grouping in the TOC, but won’t encounter a part divider page while reading.
