This mind-boggling book consists of three types of trivia: a) trivia in the colloquial definition of the word (inessential, obscure, limitedly-useful facts), b) significa for 'little-known facts that have too much importance to qualify as mere trivia' as defined by almanac writers Irving Wallace, his daughter Amy and his son David Wallechinsky and c) schoolbook knowledge and general information that constitutes 'cultural literacy' as defined by E.D. Hirsch Jr. These quizzes require patience in making sense of and unravelling the clues. The time-consuming and demanding 'Mini-Biographies' and 'A Date with History', have been divided into four levels -- easy, moderate, hard and stumper so that one can get used to the material in a graduated manner and tailor efforts according to the level of difficulty. All in all, this book refuses to let readers put it down once opened.
