"Whether online, in an email inbox or in the print version, Now I Know is a consistent delight and well worth seeking out for fans of factoids. The book flies by and readers will struggle to resist the urge to read just one more before bed." - Daily Texan

"A mind-tickling encyclopedia.... Now I Know is a treat in its oasis of learning about what you don't yet know...but are glad you found." --Brain Pickings

"Promises to serve those who are frequently surrounded by know-it-alls--or aspire to become one themselves. One of the most compelling aspects of Now I Know is that it shows how seemingly obscure facts can tell a bigger story.... So now you know." --Jewish Daily Forward

"Every story in the book is interesting, and Lewis includes a 'bonus fact' at the end of each story which is a mini mind bender on its own." - BoingBoing
