Back matter is the stuff at the end of your book, after the main sections of the book are finished. Some common items in Back matter include: Epilogue, Index, Bibliography. Back matter items are essentially chapters within a part, with one additional option to customize. The Back Matter Types menu lets you indicate an item's type.
Pressbooks lets you specify 24 types of back matter, including Miscellaneous. These types are:
- About the Author

Pressbooks organizes your back matter according to the Chicago Manual of Style as long as a back matter type has been specified from the type menu on the right side of the chapter editor.
