Twenty years ago today, Harry Potter and the Philosopher's Stone was published in the UK! You read that right, 20 years ago! In the US, it was published the following year with the title Harry Potter and the Sorcerer's Stone [J ROW, YA ROW, also in audiobook and eBook].
Of course there's no need to repeat J. K. Rowling's success story, we've all heard it before. But, here are a few statistics you may not have seen: the first printing of hardcover Harry Potter and the Philosopher's Stone was 500 copies. Five hundred! Since the first Harry Potter book was published, more than 450 million copies of the Harry Potter series books have been sold. Holy smokes!
