Dan Lewis of the popular fact-filled daily email newsletter Now I Know has authored Now I Know: The Revealing Stories Behind the World’s Most Interesting Facts, a book that’s the printed extension of the newsletter. He just announced the book on his blog and says, “It’s about 250 pages long and contains 100 stories, just like the ones you’d expect in the newsletter — bonus facts and al. Fifty of the entires are brand new, and there are about 53 or so never-before-seen bonus facts — I kind of lost count along the way. Regardless, it’s more of what you’re used to, bound together on paper with a side order of ink.” The book will be released October 18, 2013 and is available to pre-order now at Amazon.
