From The Telegraph:
The book sales have been counted and verified and the results are in: James Patterson, author of tomes such as Mistress and Private Berlin, is the world’s best-selling author since 2001.
To call Patterson prolific would be an understatement. The ad man-turned-author has put his name to 130 novels, 15 of which have publish dates in 2014 alone. But even when you divide his estimated 300 million booksales by that number, it still results with a healthy 2.3 million copies sold per title. His website claims that in 2011, a quarter of all hardback thriller novels sold were written by Patterson, and since 2006 one in every 17 novels bought in America boasted his name.
. . . .
The 130 Patterson-branded novels have approximately 45,651 pages between them. It has been 38 years since his first publication, which is 14,185 days. Bearing in mind that Patterson takes the weekends off to relax in his palatial $17.4 million Palm Beach home, and presumably celebrates Thanksgiving and other bank holidays by not putting pen to paper (he writes only in longhand), then that’s still 4.7 published pages he has consistently written every working day since 1976.
The truth of the matter is that he has help. Although Patterson only became a full-time writer in 1996, since 2002 just 20 per cent of his novels have been entirely written by him.
