You are responsible for professional editing and proofreading. This means you have to use a professional proofreader/editor. We can put you in touch with good and inexpensive professionals.


The author and Bridges of Knowledge share all revenues from sales of books, royalties and other rights 50:50. That means you get 50 cents form each Dollar your book earns.
