A great nonfiction book proposal is the key to convincing an acquisition editor you deserve a substantial advance and getting your book published.

What should be included in a book proposal?

Concept:

A brief, no more than one page description about why your book is unique.

Market:
Who will buy your book and why. Include the demographics of your potential readers and how many of them there are. If you can, quote statistics, such as baseball is the most often viewed sport on TV with x million people watching. Or x number of people attend arts and crafts shows a year. Or $xxx dollars of revenues are generated by customers buying garden tools. Whatever is relevant to your books topic.

Competition:
Similar books that have been published in the last year or that will be coming out soon. You can get an idea of soon-to-be published books by going to amazon.com, and searching under key words. When you get a listing of books that you think are similar to yours, then rank by publication date.

Include the title, author, ISBN, and a brief description. Then state why your book is better or what your book addresses that the competition doesnt.

Go to the library and read currently available books you feel are competitive to yours. Again include the title, author, ISBN, and a brief description. Then state why your book is better or what your book addresses that the competition doesnt.

All books have competitors.

Promotion:
What you will do for promotion. How will you market your book? Be specific. If you are willing to give seminars or speak at events, try to line up a few. Publishers want authors that actively market their own books. This doesnt mean that you have to spend money, but it does mean you have to expend effort.

About The Author:
Pretty self explanatory. What makes you the best author to write this book. This is not a resume; include what is relevant to the topic of the book. If you have previous books published list them, with a short description.

Media Placement:
Any newspaper or magazine articles youve been featured in. Include articles that youve written and have published. Offline, hard copy publications are better than online. Online is better than nothing. Plan ahead and in the months while youre working on your book proposal see if you can get a few articles placed. If you have just a few, include clippings. If you have more than a few, list the publication, date, title of the article. Writing a book makes you an expert in the eyes of the media, but you have to let them know youre available.

Endorsements:
If you can get a well known authority figure, expert, celebrity or author to give you an endorsement, or to commit to an endorsement, it puts you ahead in the game.

Chapter Outline or Synopsis:
Two to four pages. Each chapter is listed and the subheadings with a brief description, a paragraph or two explaining what will be included in the chapter.

Sample Chapter:
It doesnt have to be the first chapter. Pick the chapter youre most excited to write, or that you are the most knowledgeable about. The editor will judge the quality of your writing by this chapter.

The proposal not including the sample chapter can run from 10 to 20 pages.
