Scholastic is the name of the publishing company that published the Harry Potter books and its complementary novels in the United States. It is the only company to have published J. K. Rowling's novels in English besides Bloomsbury, the original publisher.
Singularity of Scholastic Harry Potter books
The main difference between Scholastic and Bloomsbury editions of the books is the covers and the spelling (Scholastic uses American spelling for words such as symbolise, which is spelt as symbolize). Also, the title of the first novel differs between the two publishers. Bloombsbury published the first novel as Harry Potter and the Philosopher's Stone, whereas in America the novel was published as Harry Potter and the Sorcerer's Stone. Other, very minor, differences in wording occur throughout the Scholastic editions, preferring American nomenclature over British, such as the word "soccer" instead of "football" or "sweater" instead of "jumper." Also, the text is a bit bigger and, unlike Bloomsbury, at the beginning of every chapter there is a small picture illustrated by Mary GrandPré.
Scholastic covers of the Harry Potter series also have a characteristic stylized logo of the franchise name, notable for the lightning-shaped P. It later became the logo of the film series.
