The average number of copies sold per title of a POD company that printed 10,000 different titles: 75 books. Damn, that's low. However, the number does not include e-books, which is the bulk of my sales nowadays. Fiction outsells non-fiction 2 to 1. Yet more fiction is published than non-fiction.Fiction is successful if it sells 5,000 copies. Non-fiction is successful when it hits 7500 copies sold. - Piaw Na
