The "Guinness Book of World Records" has reached a milestone of its own: sales of 100 million.
"The Guinness World Records book has and continues to inspire generations of record-breakers," Alistair Richards, chief operating officer of Guinness World Records, said Monday.
Guinness will mark the occasion today with events around the world, including a gathering of 500 children in New York City for an attempted record-breaking "simultaneous balloon pop."
The Guinness book was first published in 1955 and has been sold in more than 100 countries and 23 languages. The 2004 edition was released Aug. 28.
According to a well-established source -- Guinness -- other books to reach the 100-million mark include the Bible, the Koran, "Quotations from the Works of Mao Tse-tung," "The Lord of the Rings" and the Harry Potter series.
