I know that everybody is doing something like this in today's market, however it seems frivolous to do that unless you have some outlet that helps you gain visibility, because if you're not visible you can print all of the books in the world and still remain unknown. So with that in mind I wrote many short horror stories for print anthologies and articles for the newsletter where I work. I may not be as visible as some of the more prolific writers that are out there, but I am not invisible either. So today I approved a proof of some of my art work in an 8.5 X 11 format, just to test the waters. I did this through CreateSpace which is very easy to use and you can choose to market just through them and Amazon for free.
