The American English adaptations have by far received the most attention. A comprehensive list of differences between the American and British editions of the books is collected at the Harry Potter Lexicon website. The changes are mostly simple lexical switches to reflect the different dialects and prevent American readers from stumbling over unfamiliar Briticisms. Although it is common to adapt "any" text from British to American editions, in the case of the "Harry Potter" books, this standard practice has drawn criticism from readers who feel that the British English adds flavour to the series. Rowling herself expressed regret over changing the first book's title, as the Philosopher's stone is a legendary alchemical substance.
