Guinness World Records, known from its inception in 1955 until 1999 as The Guinness Book of Records and in previous United States editions as The Guinness Book of World Records, is a British reference book published annually, listing world records both of human achievements and the extremes of the natural world. Sir Hugh Beaver created the concept in order to settle arguments debated in pubs, and twin brothers Norris and Ross McWhirter co-founded the book in London in late August 1955.
