The agent will let you know what they want to see. Even with an affirmative response, they don’t always ask for a full manuscript. A nonfiction a course in miracles hasn’t been written yet in most cases, so there isn’t a manuscript to send. What publishers and agents will ask for is a proposal for your nonfiction book.
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 book’s topic.
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 doesn’t.
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 doesn’t.
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 doesn’t mean that you have to spend money, but it does mean you have to expend effort.
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.
