The Number of the Day: 200,000
Author and professor Philip M. Parker has written more than 200,000 books - aided in large part by a knowledge-gathering computer program he created himself. Parker refers to himself as “the most published author in the history of the planet.”
Related Fact: Many of Parker’s books are medical reference books. However, he is also the author of a book titled The 2007-2012 Outlook for Tufted Washable Scatter Rugs, Bathmats and Sets That Measure 6-Feet by 9-Feet or Smaller in India, which can currently be purchased on Amazon for $495.
