You can control the structure of your book with the Numberless Chapter, Invisible Part, and Section Label settings. Read on for more information on each.
In the chapter editor, you can select “Numberless Chapter” under “Chapter Types” on the right-hand menu. You would do this when:
- You have enabled Display Chapter Numbers (which automatically numbers your chapters).
- You have a handful of chapters to which you do not want to apply numbers.
This will result in a Table of Contents something like this:
2. Another Great Chapter
A Numberless Chapter
3. A Wonderful Chapter
… and applies to the TOC as well as the chapter heading.
Using a similar approach, we’ve implemented Invisible Parts.
Once you go to edit your part, you can select “Invisible Part” as a Part type in the Edit Part admin. You would do this when:
- You have a book made of parts.
- You have some chapters that you want to sit outside of one of a part (e.g. chapters that are not front-matter, but also are not contained in a main body part).
So your TOC might look like this:
1. A First Chapter
2. Another Chapter
PART I: A PART!
3. A Third Chapter
4. Yet One More Chapter
PART II: A SECOND PART!!
5. A Fifth Chapter
Customizable Section Labels
By default, all books in Pressbooks are organized with Parts and Chapters. This is how you’ll organize your book in the backend of Pressbooks. However, you can change how these terms display in your published book. Note that this setting is only available when Part and Chapter Numbers have been set to display in your Global Theme Options.
To customize the Part and Chapter labels for a book:
- Go to Appearance > Theme Options from the left sidebar menu in Pressbooks
- Under Global Options, enable the “Part and Chapter Number” setting. The “Part Label” and “Chapter Label” settings will appear
- Fill in the terms you desire in the field for each label
- Click Save Changes at the bottom of the page
The labels will change wherever they are used in the given format of your book. This includes the table of contents in some formats and the part and chapter title wraps for all formats.
Note that only some themes use section labels in the design; changing the section titles may not be necessary on themes in which those terms don’t appear.
