I would like to know how to publicize a self-published book.

I would go with non-fiction and informational/educational. EBooks are the way to go. Write in EZines that are similar to your topic of interests. Close in the "About the Author" section, a link to your blog or places that people can get more information on your topics. Use an URL to a web site or blog that holds links to your EBooks in your Email signature. Also in your signature on Social Networking sites such as Yuwie, MySpace and or ZenZuu. Lastly, create some You Tube Videos with a small blurb about your topics of interest and leave the URL to your blog or web site for more information that your viewers can go to for your EBooks. You could do an informational video for each of your EBooks. Best to you in 2009! Keep on writing.

I don't know how Createspace's revenues work but on Lulu, you don't lose anything by experimenting with eBooks. They are nearly free to produce so, other than Lulu's percentage cut, you make almost total profit. Plus they don't charge you anything to publish, only take a cut when something sells. As far as publicizing.... Talk to local booksellers about keeping five or six copies on hand to sell on consignment. I know that the Hastings chain and Borders both have sections for local authors. Another thing I have done is print up postcards with information about the book and where to buy it then go to various bookstores and slip the cards into similar books. If you write romances, slip your cards into romance novels. If you write self-help books, slip the cards into other self-help books. And so on. That way, when someone who enjoys that type of book buys the one with your card in it, they find a fun toy surprise!
