I've sometimes thought how poorly off we quizzers are for books specifically about our pastime of choice. Not quiz books, I hasten to add, of which there are more than you can shake a stick at, nor even self-help books about how to become a better quizzer (may I recommend Be A Quiz Winner!, currently available on Amazon? Too late, I already did.) No, actual books about quizzing, as a hobby, a phenomenon, call it what you will. I've read and enjoyed Marcus Berkman's "Brain Men" and Ken Jennings "Brainiac", also Mark Mason's "The Importance of Being Trivial".
Adding to that list, then, may I point you in the direction of Alan Connor's "The Joy of Quiz"? Alan Connor is the Question Editor on "Only Connect" - or he was last time I watched. So he definitely knows his subject. He's a very entertaining writer, and I thoroughly enjoyed this book which I read in the matter of a couple of evenings. Of course, it maybe helped that I did get a namecheck, even if it was just in reference to my appearance on the Antiques Roadshow (nobody wanted to look at my Queen Anne legs or my walnut kneehole).
The book is about quizzing in general, but particularly about broadcast quizzes. As you may have gathered, I look on myself as at least a student of the genre, if not actually a connoisseur, so this was right up my street, for all the fact that it's been a pretty long time since I've written much other than reviews on LAM.
Cutting to the chase, if you love quizzes, I think you'll really enjoy it. Just google it, or go to Amazon and search for either The Joy of Quiz, or Alan Connor.
