Umberto Eco recently argued that The book is like the spoon, the hammer, the wheel. Once invented, it cannot be improved. But dictionaries are different from other books. Like maps and encyclopedias – but unlike novels or newspapers – dictionaries are things you consult (while you’re doing something else) rather than things you read. For any kind of reference enquiry, the book really can be improved upon, and at Macmillan, we’ve taken the decision to phase out printed dictionaries and focus on our rich and expanding collection of digital resources.
