how to hit new york times list

The New York Times Bestseller List... and are print books dead?

I read recently that self-published books can't get onto the New York Times Bestseller List. That they weren't allowed.. or that the New York Times doesn't recognize self-published sales. I knew, when I read it, that it was false. Black Lies, my erotic romance, hit it three times last year. But it was still a welcome sight to see Hollywood Dirt, my newest baby, hit the list. Twice. Technically, three times, because it hit the eBook list AND the Combined Print/Ebook list.

What does that mean?
