As the top-selling copyrighted book in publishing history, The Guinness Book of World Records has achieved a spectacular feat. From edition to edition, it has surveyed the world's most extraordinary, authenticated facts and figures measuring all strata of human achievement and endurance, as well as natural phenomena. While it continues to entertain millions with superlatives ranging from the trivial to the sublime, it's clear that this one mammoth volume may be the best superlative of them all!
