Anybody who is interested in print-on-demand publishing needs to check out this article on the Foner Books website. I hear from a lot of people who are interested in publishing their masterpieces and print-on-demand publishing can be a cost effective method to do that. This article takes an actual publication the authors released and explains the entire process for those interested. They give complete cost comparisons for all the alternatives and explain in detail why they went the route they chose. They show a year of sales in the life of their publication as they tracked the different sales channels. Very informative look at self-publication.
