Which J.K. Rowling book was written as a charity fundraiser and published in 2008?

The Tales of Beedle the Bard was written as a charity fundraiser and published in 2008.

The book is a collection of five wizarding fairy tales mentioned in Harry Potter and the Deathly Hallows. In the story, Hermione Granger receives a copy translated from ancient runes, and one tale—“The Tale of the Three Brothers”—helps explain the Deathly Hallows.

Rowling produced seven handwritten copies before publication. One was auctioned for charity, while the published edition raised money for the Children’s High Level Group, the organization that later became Lumos. The work therefore functions both as a fictional book from the wizarding world and as a real-world charitable publication.

It is often confused with Fantastic Beasts and Where to Find Them or Quidditch Through the Ages. Those are also Hogwarts-related companion works, but The Tales of Beedle the Bard is the one built around fairy tales and released in 2008 for charity.
