The British Library has partnered with Google Arts & Culture to bring online their physical exhibition Harry Potter: A History of Magic.
Apart from various aspects of the story and the movie series, the exhibition covers for example illustrations, the history of real-world magic, and early sketches and notes by J.K. Rowling. In addition, on display are a number of items from the Museum of Witchcraft and Magic.
My favorite feature is perhaps the section covering the real-world history of various Hogwarts classes, closely followed by the animals and fantastical beasts section.
