5 Steps to Mastering Book Mapping for Your Non-Fiction Book

If you're dreaming about writing a nonfiction book but feel overwhelmed by where to begin, I have one word for you: book mapping. As a non-fiction publisher, I've worked with hundreds of authors who started with nothing more than an idea and a desire to make an impact. What made the difference? A book map.

Whether you want to share your life story, teach your expertise, or elevate your brand, book mapping gives you the structure to move from scattered thoughts to a solid manuscript. Let me walk you through the five steps I use at O'Leary Publishing to help authors confidently map their books.

What Is Book Mapping?

Book mapping is the process of creating a high-level outline of your nonfiction book from the beginning before you start writing. It organizes your ideas into a logical structure so that you always know what you’re writing, why you’re writing it, and who it’s for.

Understanding Book Mapping

Book mapping is a powerful tool used by writers and editors to visually represent the structure and content of a book. It involves creating a map of the book’s chapters, scenes, and plot points to gain a deeper understanding of the story and its elements. The book mapping process can be applied to various stages of the creative process, including manuscript development, editing, and revision.

A book map is a visual representation of a book’s contents, which can reveal gaps in the content of a nonfiction book or the storyline of a novel. It can be used to analyze elements of a book, such as chapters, characters, and themes. Book maps can be referred to as story grids, plot charts, or simply outlines. There are many different ways to map a book, and writers may find book maps by accident, out of necessity, while working on a complex project.

The book mapping process involves creating a visual map of the book’s structure, including chapters, scenes, and plot points. This can be done using index cards, a spreadsheet, or other tools. The process of creating a book map is called “mind mapping.” Book mapping helps writers identify areas where the story may be bogging down readers or exhausting them. It provides a way to visualize the story and identify areas that need improvement.

Book mapping can be used to track character development, themes, and other aspects of the story. It helps writers identify areas where the story may be lacking depth or clarity. Book mapping can be used to track the development of main characters, villains, and other story elements. It provides a way to visualize the story and identify areas that need improvement.

The book mapping process can be applied to both fiction and non-fiction writing. It is a valuable tool for writers to develop their skills and improve their craft. Book mapping can help writers create a cohesive and engaging story that resonates with readers. It provides a clear direction for revisions and improvements.

In the context of nonfiction books, book mapping can be used to create a transformation tale. A transformation tale is a table that outlines the reader’s transformation. It helps authors put boundaries around their book and decide what belongs and what doesn’t. The book mapping process can help authors create a clear plan for writing a book and stay on track.

Overall, book mapping is a powerful tool for writers to gain a deeper understanding of their story and its elements. It provides a way to visualize the story and identify areas that need improvement. By using book mapping, writers can create a cohesive and engaging story that resonates with readers.

Why It Matters

Without a book map, it’s easy to waste time writing chapters that don’t serve your message or confuse your audience. A solid map keeps your manuscript focused, saves you from future editing headaches, and helps you finish your book faster as a writer.

5 Steps to Mapping Out Your Non-Fiction Book

1. Clarify Your Core Message

Ask yourself: What is the ONE thing I want my reader to walk away with? This will be your book's North Star. Everything you write should support this core idea.

Pro Tip: Try writing your back cover copy before you write your chapters. It helps you frame your big idea and how it helps the reader.

2. Define Your Audience

Your book isn’t for everyone, and that’s a good thing. The more specific you can get about who you're writing for, the easier it is to tailor your message.

Think about your ideal reader's:

• Pain points

• Desires

• Level of knowledge on your topic

When you write with one person in mind, your words resonate more deeply.

3. Outline Your Chapters

Now it’s time to zoom out and look at the big picture by outlining your chapters. Start with 8–12 working chapter titles. Under each, write 3–5 bullet points describing the key concepts, stories, or data you want to include.

This outline becomes your writing roadmap.

Bonus: This is also helpful when pitching to publishers or agents who want to see a clear structure and flow.

4. Identify Your Signature Stories or Frameworks

Nonfiction readers love relatable stories, case studies, and clear frameworks. These elements bring your expertise to life.

Think about:

• Personal stories that illustrate your points

• Client examples

• Models or step-by-step methods you've created

These become your book's anchor points.

5. Get Feedback Before You Write

Before you write your first draft, share your book map with a coach, editor, or trusted peer. A second set of eyes can point out gaps, redundancies, or opportunities to go deeper.

At O'Leary Publishing, this is where our developmental editors shine. We help authors refine their maps so they can write with clarity and confidence.
