Which Harry Potter book did J.K. Rowling write as a charity fund-raiser in 2008?

J.K. Rowling wrote The Tales of Beedle the Bard as a charity fund-raiser in 2008.

The book is a collection of five fictional wizarding fairy tales mentioned in Harry Potter and the Deathly Hallows. It includes “The Tale of the Three Brothers,” which explains the origin of the Deathly Hallows and is central to the final novel’s plot.

Limited handwritten copies were originally produced for charity, and the commercial edition was published in December 2008. Proceeds supported The Children’s High Level Group, later renamed Lumos. The book is therefore both a companion text and a charitable publishing project.

It is often confused with Quidditch Through the Ages and Fantastic Beasts and Where to Find Them, two earlier companion books presented as Hogwarts-related library texts. Those titles are different works and do not contain Beedle’s fairy tales.
