Two new Harry Potter books will launch in October to coincide with an exhibition celebrating the 20th anniversary of the series' first book.
To be clear, neither releases will be new stories about the original characters, but rather will add further insight into the Potter world. The first book, entitled Harry Potter: A History of Magic, The Book of the Exhibition, will explore the subjects that the Hogwarts pupils studied and will serve as an in-depth guide to the British Museum exhibition.
"Each chapter showcases a treasure trove of artefacts from the British Library and other collections around the world, beside exclusive manuscripts, sketches and illustrations from the Harry Potter archive," said a statement from the book's publisher, Bloomsbury.
"Readers will be able to pore over ancient spell books, amazing illuminated scrolls that reveal the secret of the Elixir of Life, vials of dragon's blood, mandrake roots, painted centaurs and a genuine witch's broomstick, in a book that shows JK Rowling's magical inventions alongside their cultural and historical forebears."
The second Harry Potter, A Journey Through a History of Magic will look at the stories behind the witches, wizards, spells and magic creatures. Bloomsbury says "this spellbinding book takes readers on a journey through the Hogwarts curriculum, including Herbology, Defence Against the Dark Arts, Astronomy, Divination and more. Discover the truth behind making the Philosopher's Stone, create your very own potion and uncover the secret of invisible ink."
The British Museum's dedicated exhibition opens on 20 October 2017, and runs until 28 February 2018.
