e.exploreprovides complete and visually arresting reference at a new level. Topics are presented thematically, on double-page spreads, in a clear and logical progression - ending with a comprehensive glossary and index. Reference pages provide a clear and compelling overview of each topic. On every page, a range of ready-reference tools deliver information at a glance: data boxes; timelines; annotated and step-by-step photography; digital images and artworks. E-links lead you to online information you can t get in a book: live and archive footage; sound buttons; interactive polls, quizzes, and games; links to organizations and the latest research. Each e-link tells you which keyword to key in - then Google and DK take you straight to the safe, appropriate, and authoritative online information, and ensure that all web links are regularly monitored and updated.
