Quidditch Through the Ages is a spin-off from the books in Rowling's Harry Potter series and is intended to be one of the books Harry and his friends use themselves. This book is a history of the magical sport, Quidditch, played by witches and wizards and enjoyed by Harry Potter and his friends in Rowling's books. This book is purportedly borrowed from the library of Harry's school, the Hogwarts School of Witchcraft and Wizardry, and is intended to be comprehensive in scope, beginning with the history of broomsticks, covering the changes in the game over the centuries, and ending with an overview of Quidditch today. Quidditch Through the Ages serves as an actual sports handbook written in the same style as any sports handbook, and it provides detailed information about Quidditch teams, players, and past matches.
