We all went crazy for a second there and started digging through history for proof of the Doctor.
But have you guys ever studied Doctor Who history? It's my kind of a history book.
I got the book Doctor Who: A History last week and managed to read it all. It was a-mazing. It was rather nice seeing the origin behind the show and the history of each Doctor. The only thing I didn't like about it was its shortness on detail to Nine, Ten and Eleven.
I'd recommend a read to any Whovian wanting to know the history of both the Doctor, the show and even the comics. And if you want to learn about Gallifrey I'd say you give a listen to the catchy song
