The Oxford English Reference Dictionary extends the aims of conventional dictionaries to be more useful, more practical, and more informative. It combines the coverage of an authoritative Oxford dictionary containing spellings, grammar information, pronunciations, and word origins, with in-depth encyclopedic entries. A 16-page full-colour map section, including the latest border and name changes, is accompanied by a large section of reference appendices including countries of the world, prime ministers and presidents, the body, the solar system and a chronology of world events.
