A Houston Chronicle article talks about book promotion from the different perspectives of several successful authors including Rebecca Skloot, author of The Immortal Life of Henrietta Lacks and others.
The story of how Skloot's created buzz for her book (beginning years before its publication!) caught my attention because, by coincidence, I'd just finished reading The Immortal Life of Henrietta Lacks . Of course, I read the book because of all the media attention it had received (yes, successful book promotion campaigns work for book publicists, too). But I found it fascinating to see the extent to which Skloot's generated all that book publicity for herself. She didn't wait for her book publisher to do it for her.
In the article, you'll read about authors who used Facebook and Twitter to generate buzz for their book, and you'll read about at least one author who avoided social networking. Finally, you'll read about an author whose appearance on a national TV show -- "Good Morning America" -- was the making of his book and proved, to him, that traditional book promotion strategies still work best (when you're lucky enough to score the right mix of major book promotion opportunities, that is).
Ask half a dozen authors whose books have been successful how they created buzz for their books, and you'll get six vastly different responses. But the cool thing is that we can learn from all of them, and we can adapt their book promotion strategies to our own book publicity goals, needs, and preferences. There's something to be learned from all successful authors.
