Atheist Books Are Bestsellers

 
Publishers Weekly has an article on books about atheism [Believe It or Not]. They report on the number of copies of these books that have been sold. Here's the summary complied by Friendly Atheist [How Well Are the Atheist Books Selling?].

• The God Delusion by Richard Dawkins: 282,000 copies sold
• The End of Faith by Sam Harris: 250,000 copies sold (says this article)
• Letter to a Christian Nation by Sam Harris: 123,000 copies sold
• God is Not Great by Christopher Hitchens: 58,000 copies sold
• Breaking the Spell by Daniel Dennett: 52,000 copies sold
• God: The Failed Hypothesis by Victor Stenger: 60,000 copies shipped

These are impressive numbers, especially since the soft cover editions aren't out yet.

In case you're thinking about trying to make a living writing books like these, consider that the author gets about $2 per book. There are considerable expenses that need to be covered by that royalty payment so, in most cases, the net income isn't enough to induce you to quit your day job.
