An interesting post on "The Right Way to Build a Book" from Theodore Savas of small historical press Savas Beatie:The fundamentals for selling any book are essentially the same. Here is the secret: talk about your book as often as you can, with as many people as you can, for as long as you can, wherever you can, even if you don't sell a single copy when you do. Oh, and there is a follow up: REPEAT--REPEAT--REPEAT.
...Do you have copies with you all the time? Have you sent a letter to everyone you know telling them about your book? Are you talking about your book as often as you can, with as many people as you can, for as long as you can, wherever you can, even if you don't sell a single copy when you do? Are you asking people who they know in the media that can help you?
The honest answer to that question will explain a lot the next time you open a royalty statement or read in the news about some author who has a bestseller that is no more interesting than the book you spent years working on. What does he know that you do not? What is he willing to do that you are not?
