We gotta get back to Hogwarts in this episode, where we chat about MuggletNet's Ultimate Unofficial Harry Potter Hogwarts Handbook. Katy and Emily are joined by Potterversity producer Laurie Beckoff and Marissa Osman, two of the authors of the latest release in MuggleNet's Unofficial Reference Library. Following a spellbook, character compendium, and bestiary, this book branches out beyond lists to chronicle every known detail about the wizarding world's most famous school, from history to hallways to inhabitants. Hear about the research, writing, and editorial process that went into such a massive undertaking. Laurie and Marissa talk about their approach and how their academic backgrounds came in handy. We discuss the difficulty of determining what counts as canon and how to reconcile information from the books, films, video games, interviews, tweets, and Pottermore. Even within the seven novels, Hogwarts is full of contradictions and mysteries - mistakes or magic? Hogwarts feels like home to so many readers. We share our favorite spots in the castle, fun tidbits about the school, and what else we want to know. What secrets of Hogwarts are yet to be discovered?
