The award-winning Macmillan English Dictionary was first published in 2002 in both British English and American English. Crafted by teams of lexicographers in Great Britain and the United States, it had as its source a corpus, a database containing millions of examples of English as used around the world. Extensive analysis of this corpus of real spoken and written text, using state-of-the-art technology, allowed the dictionary writers to reveal fresh information about how and when words are used.

In 2007, the 2nd Edition of Macmillan English Dictionary was published with carefully researched content for learners of English around the world. An example of this content is the information provided in the so-called 'Get it right!' boxes

The Oxford English Dictionary (OED) is widely regarded as the accepted authority on the English language. It is an unsurpassed guide to the meaning, history, and pronunciation of 600,000 words— past and present—from across the English-speaking world.

As a historical dictionary, the OED is very different from dictionaries of current English, in which the focus is on present-day meanings. You’ll still find present-day meanings in the OED, but you’ll also find the history of individual words, and of the language—traced through 3 million quotations, from classic literature and specialist periodicals to film scripts and cookery books.

The OED started life more than 150 years ago. Today, the dictionary is in the process of its first major revision. Updates revise and extend the OED at regular intervals, each time subtly adjusting our image of the English language.
