Several world records that were once included in the book have been removed for ethical reasons. By publishing world records in a category, the book may encourage others to try to beat that record, even at the expense of their own health and safety. For example, following publication of a "heaviest fish" record, many fish owners overfed their pets beyond the bounds of what was healthy, so entries such as these were removed. The Guinness Book also dropped records within their "eating and drinking records" section of Human Achievements in 1991 over concerns that potential competitors could do harm to themselves and expose the publisher to potential litigation. These changes included the removal of all liquor, wine, and beer drinking records, along with other unusual records for consuming such unlikely things as bicycles and trees. Other records, such as sword swallowing and rally driving (on public roads), were closed from further entry as the current holders had performed beyond what are considered safe human tolerance levels. Earlier editions also made reference to former King Zog of Albania holding the world record for amount of cigarettes consumed being c.150 per day.
There have been instances of closed records being reopened. For example, the sword swallowing record was listed as closed in 1990 Guinness Book of World Records, but the Guinness World Records Primetime TV show, which started in 1998, accepted three sword swallowing challenges (and so did the 2007 edition of the Guinness World Records onwards). Similarly, the speed beer drinking records which were dropped from the book in 1991, reappeared 17 years later in the 2008 edition, but were moved from the "Human Achievements" section of the older bookto the "Modern Society" section of the newer edition.
As of 2010, it is required in the guidelines of all "large food" type records that the item be fully edible, and distributed to the public for consumption, in order to prevent food wastage. Chain letters are also not allowed. "Guinness World Records does not accept any records relating to chain letters, sent by post or e-mail. If you receive a letter or an e-mail, which may promise to publish the names of all those who send it on, please destroy it, it is a hoax. No matter if it says that Guinness World Records and the postal service are involved, they are not."
On 10 December 2010 The Guinness World Records rested its new "dreadlock" category after investigation of its first and only female title holder, Asha Mandela, with this official statement:
"Following a review of our guidelines for the longest dreadlock, we have taken expert advice and made the decision to rest this category. The reason for this is that it is difficult, and in many cases impossible, to measure the authenticity of the locks due to expert methods employed in the attachment of hair extensions/ re-attachment of broken off dreadlocks. Effectively the dreadlock can become an extension and therefore impossible to adjudicate accurately. It is for this reason Guinness World Records has decided to rest the category and will no longer be monitoring the category for longest dreadlock."
In 1976, a Guinness Book of World Records museum opened in the Empire State Building. Speed shooter Bob Munden then went on tour promoting the Guinness Book of World Records by performing his record fast draws with a standard weight single-action revolver from a western movie type holster. His fastest time for a draw was .02 of a second. Among exhibits were life-size statues of the world's tallest man (Robert Wadlow) and world's largest earth worm, an X-ray photo of a sword swallower, repeated lightning strike victim Roy Sullivan's hat complete with lightning holes and a pair of gem-studded golf shoes for sale for $6500.[ This museum has been closed since.
In more recent years the Guinness company has permitted the franchising of small museums with displays based on the book, all currently (as of 2010) located in towns popular with tourists: Tokyo, Copenhagen, San Antonio. There were once Guinness World Records museums and exhibitions at the Trocadero in London, Bangalore, San Francisco, Myrtle Beach, Orlando, Atlantic City, New Jersey, and Las Vegas, Nevada. The Orlando museum, which closed in 2002, was branded The Guinness Records Experience; the Hollywood, Niagara Falls, Copenhagen, and Gatlinburg, Tennessee museums also previously featured this branding.
While some displays are dramatic, like the statues of the world's tallest and shortest people, or videos of records being broken, much of the information is presented simply with text and photos.
The 55-year history of Guinness World Records began with a single question, the type that has been repeated millions of times at dinner parties, pubs, classrooms and work places across the globe.
During a shooting party in County Wexford, Ireland, in 1951, Sir Hugh Beaver – then Managing Director of the Guinness Brewery – asked a simple question: what was Europe’s fastest game bird? Despite a heated argument and an exhaustive search within the host’s reference library the answer could not be found.
Sir Hugh realized that similar questions were going unanswered all around the world, and that a definitive book containing superlative facts and answers would be of great use to the general public. With the help of the London-based fact-finding twins Norris and Ross McWhirter, he set about bringing this definitive collection of superlative facts to reality. On 27 August 1955, the first edition of “The Guinness Book of Records” was bound and, by Christmas that year, became Britain’s number one bestseller.
Over the intervening years, copies of The Guinness Book of Records – later renamed Guinness World Records – have continued to fly off bookshop shelves. During this time, it has become clear that, to our readers, a world record is more than a simple fact: it’s a means of understanding your position in the world… a yardstick for measuring how you and those around you fit in. Knowing the extremes – the biggest, the smallest, the fastest, the most and the least – offers a way of comprehending and digesting an increasingly complex world overloaded with information.
