A non-fiction proposal is a written document that outlines an idea for a book or other project based on factual information. It typically includes an overview of the proposed work, as well as detailed information about the intended audience, the author's qualifications and experience, and a chapter-by-chapter breakdown of the content. The proposal also usually contains a market analysis that demonstrates the potential demand for the book or project, as well as a description of how it will be published and promoted. A nonfiction proposal is typically submitted to publishers in hopes of securing a contract to write and publish the work.
