You can write biographies, cookbooks, indices, how-to manuals, town histories, or travel books. It is a known fact in the publishing world that nonfiction sells better than fiction. The field is wide open. The list is as infinite as your imagination. Take these few steps towards filling bookstore shelves with your nonfiction books.
Everyone is an expert at something. Find your specialty and you can write many nonfiction books on that topic. Make a list of things you do well.
Create an outline for each item on your list. Choose one topic and write down all the key points about it. For instance, a book on nonfiction writing would include key points such as Choosing a Topic, Manuscript Layout, Selling and Marketing, Research Citations, to name just a few.
Flesh out each key point with detailed sentences. Ideally, each of your key points will become a chapter in your nonfiction book.
Readers of nonfiction love maps, photographs, charts, and other graphics that support your writing. Add photos, diagrams, and other graphics to enhance your book.
Always give credit to your sources. Add a reference page to indicate where you did the research for your book. A professional nonfiction book does not overlook the citation of sources.
Put a resource section at the back of the book. Buyers of nonfiction feel they have received an added bonus when they are provided additional resources to find out more information. Go easy on this page though; there is no need to make this more than three pages or so.
Stay organized. Start a file cabinet (or file on your computer) to keep track of your ideas and your work. Check your local community college for nonfiction writing workshops. They are usually very inexpensive and often free to senior citizens.
Don’t get bogged down in detail. You don’t want your nonfiction book to bore readers to death. Say what you need to say, and move on.
