How to write a nonfiction book proposal: A step by step guide

Instead of writing the entire book, then trying to interest an agent who then pitches an editor (which is how it works with novels)--you write a proposal first if you’re a nonfiction author. The proposal convinces agents and publishers why your book should exist.

A proposal is usually 15-20 pages double spaced, exclusive of any sample chapters. It begins with a simple cover page with title, author, and contact information followed by a table of contents page for the proposal, not the book.

Start with a 3 page overview of the book. Focus on the problem; then propose your suggested fix or view. Show how your book explores a unique idea or point of view.

Write a 2 page narrative biography. Don't go into your personal details overmuch. The biography should explain why you are the person best suited to write the book, your professional credentials, and any awards or achievements.

Demonstrate your target audience. Your audience cannot and should not be 'everyone.' Think critically and be honest with yourself. Who is most likely to buy your book. And secondly who may buy your book.

Find 5-10 similar titles and explain how your book fits in or stands out from them. Give the title, author, publisher, publication year, page count, price, and the ISBN. Give a 150 word summary for each book that includes how your book will be different.

Discuss how you will help get the word out. Authors are expected to assist with social media, television, podcast appearances and more these days. Don't just note your stats; explain why certain platforms will help for your particular topic.

In a few sentences, specify how long you think the book will be, how long it will take you to write it, if you need any special reviews or permissions to include certain material, and if there are any costs you'll incur in the process of writing.

Finish up with a chapter by chapter synopsis, 250 words per chapter. Then include one complete sample chapter.

Bottom Line: Nonfiction can be a less daunting prospect to publish since you aren't expected to write an entire book before knowing someone will publish it. However, authors should take care and time to make a great business case for why their book should exist.
