The software giant Microsoft surprised commentators this week when it announced plans to produce a somewhat traditional publication - a dictionary. The corporation is collaborating with British publisher Bloomsbury, the US-based St Martin's Press and Pan Macmillan Australia to produce the Encarta World English Dictionary, to be available next year in electronic and print formats. The companies have been working together for three years on the dictionary, which will include more than three million words. Microsoft is billing the publication as: "the first World English Dictionary" because editions in American and British English are being produced from a single database.
