How to Write and Sell Your First Nonfiction Book by Oscar Collier, Frances Spatz Leighton is an excellent how-to book on writing. Note: I have written and published over two dozen magazine and trade journal articles in over a dozen different publications. This gives me insight on how the free-lance business works. Most want to be authors know little to nothing on how to write and sell their first book. This book tells you how the process works. It covers the various types of books. It gives step by step guidance. It shows you how to pitch an idea instead writing a book on speculation. If you are even thinking of being an author, it is worth reading. My advice is to get and read this book.
