What is the name of J.K. Rowling’s wizarding textbook spin-off published for Comic Relief?

J.K. Rowling’s wizarding textbook spin-off published for Comic Relief is Fantastic Beasts and Where to Find Them. Bloomsbury issued it in 2001 as a charity book presented as Harry Potter’s Hogwarts textbook by the fictional author Newt Scamander.

The book is designed as a facsimile of Harry’s school copy, complete with humorous marginal notes attributed to Harry and Ron. It catalogues magical creatures and explains the classification system used by wizarding authorities. Proceeds supported Comic Relief, a British charity that funds projects addressing poverty and social injustice.

Rowling later expanded the fictional textbook into a screenplay series beginning with the 2016 film Fantastic Beasts and Where to Find Them. The film continuity made Newt Scamander an on-screen protagonist, while the original charity book remains a short reference-style work.
