John Locke made history (again) yesterday when he was announced as the first indie writer to sell 1 million Kindle Books. In case you are wondering about Amanda Hocking – who broke a million a while back – that was for e-books in all formats through all retailers. On the same day, John Locke released his how-to book, How I Sold 1 Million eBooks in 5 Months! which broke into the Top 100 items in the Kindle Store at some point yesterday evening. It’s now at #54. Pretty impressive for a self-published non-fiction book, and pretty impressive for a self-help book, or for any book on writing/publishing/marketing.
