Archive Panic: The Guinness organization currently catalogs over 40,000 records. Only about 4,000 of them are printed annually in the book; about 15,000 are on their website, but if you need an official verification of a record you need to write directly to the organization.
Author Existence Failure: Sadly one of the twin brothers who founded the Guinness Book Of Records, Ross McWhirter note He was also an extreme conservative and right-wing commentator was murdered on his own doorstep by Irish terrorists for his trenchant comments on how The Troubles should be dealt with. His brother carried on the series after his untimely death.
From 1991 to 2007, records related to "gluttony" (most food or drink consumed in the fastest time) were dropped as potentially dangerous. When they were reintroduced, they were moved from the "Human Achievements" section to the "Modern Society" one, which might be seen as less of an endorsement.
Sword-swallowing records were included but frozen from 1990 to 2006, due again to fears that the maximum safe limit of human physiology had been reached.
You will look in vain for World's Youngest-Ever Mother, for instance: as the record-holder was only five, this category was discreetly dropped partly because of the paedophilia connotation and partly because there was a well-grounded fear that somebody out there would seek to '''beat''' this record, with legal implications for any publication seen to be implicitly encouraging the attempt. note The "youngest mother" record was also dropped because the unfortunate holder, from a Third World South American nation, had eaten a diet of meat packed with fertility hormones which had brought about a VERY early puberty. As she was indeed also a victim of paedophilia - a male relative was later imprisoned - the Guinness Book deleted all reference to her, out of respect for all the misfortunes she had suffered.
