What is the title of the first Harry Potter book published in the United Kingdom?

The first Harry Potter book published in the United Kingdom is Harry Potter and the Philosopher’s Stone.

Bloomsbury published the novel in Britain on 26 June 1997. It introduces Harry Potter, Hogwarts School of Witchcraft and Wizardry, and the central friendship of Harry, Ron Weasley, and Hermione Granger.

The book was published in the United States under a different title: Harry Potter and the Sorcerer’s Stone. “Sorcerer’s Stone” replaced “Philosopher’s Stone” for the American edition, so readers sometimes treat the two titles as separate books. They are editions of the same first novel.

The story’s title refers to the mythical substance that grants long life and can transform metals into gold. The novel began a seven-book series that became one of the most commercially successful publishing franchises in modern history.
