THE seventh and final Harry Potter book sold more than 11.3 million copies during its first 24 hours on sale in Britain, Germany and the United States, according to figures compiled overnight.
A total of 11,350,927 copies were sold in the three countries on the first day, according to figures released by its publishers.
A total of 2,652,656 copies of Harry Potter And The Deathly Hallows were sold in Britain 9.01am AEST Saturday, making it the fastest-selling work in British history, publishers Bloomsbury said.
Although they had predicted it would sell three million, the figure still beat the previous record set by its series predecessor, Harry Potter And The Half-Blood Prince, which sold just over two million.
Bloomsbury said it sold 398,271 copies of the English language edition in the same period in Germany.
But these figures were dwarfed by sales in the United States, where the book shifted around 8.3 million copies in its first 24 hours.
These would be staggering figures over a lifetime of sales. But look back over those few paragraphs again, and register the time frame.
TWENTY FOUR HOURS.
