303030, what kind of nonfiction title do you want to do? Will it be regional-interest, or appeal nationally?
I have two regional history books published now, and both of these appeal largely to Cincinnati readers, but their themes appeal to people interested in mass transit all over the country. So, my topics are more narrow-focused, but the first one,
The Cincinnati Subway is still selling very well and is entering its 5th printing after being out for a year and a half. The subway book is regional to be sure, but it has a lot of information and photographs that appeal to railroad/street railway fans across the nation.
The second book is
Cincinnati on the Go came out a couple of weeks ago, and so far readers I've spoken to really like it. This second title is a pictorial history of mass transit in Cincinnati, so it's not text heavy like the first book.
Now from this perspective, to answer your questions:
How did I decide to write the book? Simply put, it hadn't been done, and I wanted to write a whole book. I was interested in the story of the subway, but there wasn't any information on it, except for a few newspaper or magazine articles. No book. The subway was built in the 1920s and was never finished or ever used. Many people around Cincinnati have always wondered about the subway, and my book was the first--and only--book about it. The publisher is thrilled with it and it sells very well. I decided to do Cincinnati on the Go so I could expand on the mass transit pictures in the subway book.
I was working a full time job and writing articles on the side for a radio trade magazine that paid fairly decently. I knew I wouldn't make a fortune writing the articles, but did it anyway because it was fun and I knew the subject matter. With royalties coming in from the book, that could also supplement my income, so why not write the book?
How do you estimate how much your title will sell? Again, it depends on your subject matter. If you're writing a book on the history of agriculture in the Northwest, then it will probably sell OK, but not put you on the best seller list. If you're doing a comprehensive book on the Civil War, then you will probably do well, but you'll have to outdo Shelby Foote and the other many titles on the Civil War. How well you'll do depends on the subject matter, what else has been written about it, what kind of distribution the publisher has, how the book is marketed (which you'll be doing largely yourself), and many other factors, including if book buyers are familiar with your name. If your name is Tom Clancy, and you're coming out with a nonfiction book on submarine warfare, then you're going to do really well. If your name is Joe Nobody, then you'll have to really work at your marketing.
How much time to research and write? Figure at least six months to a year, maybe more, depending on the subject matter. You'll be working every evening and weekend. If you're married and/or with kids, you'll have to work out some compromises with them. After working on the subway book for several months, my wife allowed me just one hour a night to do that so I could spend time with her and build a happy marriage.
How much time for promotion? I don't know, several hours a week? Maybe more, maybe less. Get the book on your website, contact bookstores and arrange signings, while you're at work, think of additional offbeat ways to promote your book. Once it's out, don't let it die on the shelves. People have to know about it to buy it. Try to get on local radio and or TV morning shows. (I never was able to do this, and I tried tried tried). Send out press releases to any paper you can think of. Alert the columnists in your local papers who might be interested in the subject matter. That worked getting the word out about the subway book.
So far I've received more in royalties for the subway book than I've gotten for writing recent articles, but I haven't really been writing all that much. It's easy to write a 1500 word article--takes me about five hours of actual writing. It's hard to write a 50,000 word nonfiction manuscript--took me over six months.
And yes, my book credits are very important to my writing career. A published book shows that my words are not only publishable--by a real publisher, but they can make money, too.
Hope that answers your questions.
