Say the words "reference book" and most people think of something boring. But DK Eyewitness Books proves that doesn't have to be the case by showing readers in pictures what other books only tell them in words. What makes DK Eyewitness Books so compelling is a "lexigraphic" design style developed by Peter Kindersley. He created a design approach that integrated words to give meaning to the pictures. Rich with content, Eyewitness Books use a lively mix of full-color photographs and illustrations, cutaway and cross-section views, 3-D models, and maps to help the reader visualize the subject. Parents and educators quickly embraced the lexigraphic approach. The rest, as they say, is history.
