For the new millenium comes a new edition of Macmillan's one-volume encyclopedia. Every single one of ever 25,000 entries has been reviewed and updated and hundreds more added to cover the greatest possible width of topics - countries of the world, science and technology, space, natural history, medicine, politics, sport, people, literature, art and history. Other new features include design, photographs, diagrams and illustrations and a colour plate section with updated maps and flags of the world. There is also an easy reference section at the back of the book which includes conversion tables, statistical information and chronologies.
