In the 1955 edition the most expensive bottle of wine would have set you back GBP8; but the current record-holding bottle of plonk sold for a staggering GBP75,000. However, not everything's changed in the past six decades - did you know that Robert Wadlow, who towered 2.72 m (8 ft 11.1 in) in 1940, still holds the record for tallest man? At least for now - GWR in another dimension! As if the book weren't exciting enough, our "See It 3D" augmented reality app is back with new features that bring the book to life! Use your smart device to unlock interactive elements that literally jump off the page. See how you size up to Wadlow, meet deep-sea creatures up close, play our Splat-the-Maggot game and much more.
