LONDON (AP) -- It has been almost two decades since Harry Potter emerged from his cupboard under the stairs and the British Library plans to mark the occasion with an exhibition.

The library announced Monday that it will mount an exhibition dedicated to the boy wizard next year, the 20th anniversary of “Harry Potter and the Philosopher's Stone.”

The novel -- titled “Harry Potter and the Sorcerer’s Stone” in the U.S. -- was the first in J.K. Rowling’s seven-book series, which spawned a film franchise, a theme park and a hit play that recently opened in London’s West End.

The exhibition will include material from the archives of Rowling and publisher Bloomsbury, alongside centuries-old treasures from the British Library’s collection.

It is due to run from Oct 20, 2017, to Feb. 28, 2018.
