 How Many Books?

I got an email from someone who wanted to know the total number of books that I've sold.

Answer: I have no idea. I suppose I could dig out all my old royalty statements (which are on paper), spend a day doing data entry, and come up with a total. But that's way too much work.

Then I remembered that Amazon provides data from BookScan for authors. The only data available is for the past eight weeks:

 

bookchart

That's 7,367 books sold in 56 days, which works out to an average of 131.6 per day. I've been writing books for about 18 years, but sales weren't always as good as they currently are -- although they have also been much better. So let's assume 100 books per day for 18 years. That's 675,000 books.
