What is a nonfiction book proposal?
- Nonfiction is usually sold on proposal, not a finished manuscript.
- A proposal argues the book's concept, market, and the author's platform.
- Core sections: overview, audience, comps, author bio/platform, outline, sample chapters.
- Platform — your reach and authority — carries heavy weight.
- It is a business case as much as a writing sample.
A nonfiction book proposal is the document used to sell a nonfiction book to agents and publishers before the book is written. It makes the case for the book across standard sections: an overview of the concept, the target audience and market, comparable titles, the author's bio and platform, a chapter-by-chapter outline, and one or two sample chapters. Unlike fiction, nonfiction sells on this proposal rather than a completed manuscript.
Chapter i·Why it matters
The proposal is the central document of nonfiction publishing, and understanding it reframes the whole path: you are selling an argument and a plan, not a finished book. It is a business case — proving there is an audience, that you can reach them, and that you can deliver. Knowing what a proposal contains, and that platform often matters as much as prose, is foundational to pitching nonfiction successfully.
Chapter ii·What to include
- An overview making the case for the book.
- The target audience and market size.
- Comparable titles and how yours differs.
- Your bio and platform — reach and authority.
- A chapter-by-chapter outline.
- One or two polished sample chapters.
Chapter iii·Example
A journalist pitching a book on urban farming writes a proposal: an overview of the concept, the size and reach of the audience, three comps, her platform (a popular newsletter and speaking history), a full chapter outline, and two sample chapters. An agent acquires the book on the proposal — months before the manuscript exists.
