J.K. Rowling’s Harry Potter publisher, Bloomsbury, is based in London.
Bloomsbury Publishing is an independent British publishing house founded in 1986 by Nigel Newton. It became internationally prominent after acquiring the United Kingdom publishing rights to Harry Potter and the Philosopher’s Stone, which it released in 1997.
The company’s name comes from Bloomsbury, an area of central London known for publishing, universities, museums, and literary associations. Its headquarters are in London, although the company operates internationally and has offices in other countries.
The publisher is sometimes confused with Hogwarts locations because “Bloomsbury” sounds like a place from the wizarding world, but it is a real London district and the name of a real publishing company. Scholastic handled the American editions of the Harry Potter novels.
