BTW, for those of you who like QI and are fascinated by the errata of cartography, may I suggest The Phantom Atlas by Edward Brooke-Hitching? Seriously, this book is a real eye-opener about some of the cartography of yesteryear, with all the myths, the frauds, and the just plain wishful thinking. And you'd be surprised at how recently some were debunked: at least two were only debunked in the 21st Century...
