Publishers Marketplace had an interesting article about the average number of books sold by most POD publsihers like AuthorHouse or Iuniverse. The number is around 200 or less--with most of these being books bought by friends, relatives, etc. Okay. I buy that. No arguements here.
But what's the average number of books bought by readers from a standard 'traditional' publisher? I know a lot of traditional paperback houses print roughly 2000 to 2,500 for a first printing run. But do the sell that many? Does an average sold run mean 2,000 books sold? Especially for fiction.
I suspect there are a hell of a lot of warehouses bursting at the seams with books lying around--books from traditional houses incapable of being sold.
