What is the name of the Hogwarts textbook credited to Kennilworthy Whisp in J.K. Rowling’s wizarding world?

Quidditch Through the Ages is the Hogwarts textbook credited to Kennilworthy Whisp.

Rowling created the book as a companion work to the Harry Potter novels. In the story, it is held in the Hogwarts library and is presented as a reference history of the wizarding sport of Quidditch. The fictional author, Kennilworthy Whisp, writes about the sport’s development, rules, equipment, teams, and historical controversies.

The real-world edition was published in 2001 under the pseudonym Newt Scamander, with Rowling named as the person who made the library copy available. It was packaged as a charity book, alongside Fantastic Beasts and Where to Find Them, and proceeds supported Comic Relief.

The book helps make the wizarding world feel like it has its own literature and school culture beyond Harry’s main adventure. Its playful annotations, including notes attributed to Harry Potter and Ron Weasley, are part of the fictional presentation. The title refers to the sport’s imagined history, not to a real academic textbook.
