The article will lead you to the British Library Exhibition found here. As you scroll through, there is an immense amount of articles and videos to see ranging from a closer look at the courses taught at Hogwarts to an interview with Jim Kay, the illustrator who drew the scenes for the illustrated Harry Potter books.
I immediately went to the Ripley Scroll and started reading through it. It's pretty cool how the paper is really small and then it zooms in to certain parts as you scroll down with facts about it.

Have you seen the exhibition already? What's your favorite part of it?
