Author Jim C. Hines has an entry entitled Self Publishing "Success" Stories and they talk about some of the claims of self-publishers:
1. John Grisham self-published A TIME TO KILL. Actually, Grisham sold A TIME TO KILL to a small publisher, Wynwood Press, who did a 5000-copy print run. Grisham bought the remaindered copies, which he sold himself. While this is the sort of hard work self-publishing often involves, A TIME TO KILL was certainly not a self-published book.
