Which fictional Hogwarts textbook did J.K. Rowling publish for charity in 2001?

J.K. Rowling published the fictional Hogwarts textbook Fantastic Beasts and Where to Find Them for charity in 2001.

The book is presented as a copy of the textbook used by Hogwarts students and attributed within the fiction to Newt Scamander. Its main text is a guide to magical creatures, but Rowling adds humorous annotations supposedly written by Harry Potter and Ron Weasley.

The book was published alongside Quidditch Through the Ages. Proceeds from the editions were donated to Comic Relief, supporting the charity’s fundraising work. These companion books are short fictional works connected to the Harry Potter world rather than additional novels in the main seven-book story.

The same title later became the basis for a film series and Rowling’s first published screenplay. The 2001 book and the 2016 film share a title and wizarding-world connection, but they are different works with different formats and stories.
