The new Guinness World Record for most books toppled in a domino fashion was set on 28 January 2015.
During a sales conference in Old Windsor, Berkshire (UK), United Biscuits employees set up a domino of well over 5,000 books, out of which 5,318 had successfully toppled and were counted for a new record.
The previous Guinness World Record of 4,988 books toppled was set in March 2014 in Częstochowa, Poland.
