Kennilworthy Whisp is the fictional author credited within J.K. Rowling's Wizarding World for Quidditch Through the Ages. Presented as a Hogwarts library book, it explains the history, rules, equipment and development of Quidditch, including early broom games and notable teams, in the style of an in-universe sports reference work rather than a conventional novel. The real-world book was written by J.K. Rowling, with Whisp functioning as part of the fictional framing. This catalogue record should therefore be treated as fictional authorship, not as a separate real writer. The book fits Wizarding World companion material, fantasy reference and illustrated or encyclopaedic children's fantasy. Quidditch Through the Ages is the only meaningful real-world entry point for this fictional byline. Read more Less
