With over 13,000 A-Z entries, more than 1500 images, 150 special box features and a 32-page world atlas the Philip's Encyclopedia 2003 provides information on all areas of knowledge and is fully revised and updated for 2003. The chronology and ready reference sections have been revised and updated to include contemporary events and figures such as Osama bin Laden and the war in Afghanistan and recent achievements in sports, arts, and science and technology. Significant attention has been paid to articles on current affairs and international politics, nations of the world, technological innovations, and major figures in popular culture, literature and science. It also features a colour-illustrated 64-page identification guide to astronomy, the human body, mammals, birds, butterflies and trees. This should enable readers to know a kestrel from a harrier, spot the constellation of Cassiopeia, find the deltoid muscle, distinguish between a cypress tree and a yew, and discern a fallow deer from a roe deer.
