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.
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. To bundle complete books inside one project (omnibus or box set), use book volumes instead.
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.
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:
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.
