The group-0 ISBN publisher codes refer to the United States publisher codes within the International Standard Book Number (ISBN) system. Each ISBN is divided into several parts, including a prefix element (which is currently only '978' or '979'), a registration group element (indicating a particular country or language area), a publisher element (identifying a specific publisher), and an item number (representing a specific edition or format of a book).
