21 Facts You Might Not Have Known About The Harry Potter Series

I was ten when I read the first Harry Potter book, and though I can’t say that was what kickstarted my love of reading (I was always quite the bookworm), it was the first book I became completely obsessed with. I devoured it in two days and spent the next several weeks daydreaming and play-pretending that I was a wizard. As you might guess, when my 11th birthday rolled around, I was gravely disappointed that my Hogwarts acceptance letter hadn’t arrived.

I read and reread that first book so many times that the binding started unraveling. It is my most battered copy of any book I own, as well as my favorite.

I think some of my very best childhood memories involve Harry Potter in some way – whether it’s reading the books, or watching the reruns of the movies on TV every holiday season. Which is why the fact that it’s the 21st anniversary of the year Harry Potter and the Philosopher’s Stone came out is making me very emotional.

So, to celebrate it, here are 21 facts about the Harry Potter series that you might not have known.
