"A ready reference aid and an inspiration to designers . All in all the best book now available on symbols." --Library Journal This unparalleled reference represents a major achievement in the field of graphic design. Famed industrial designer Henry Dreyfuss recognized the importance of symbols in communicating more quickly and effectively; for many years he and his staff collected and codified graphic symbols as they are used in all walks of life throughout the world. The result is this "dictionary" of universally used graphic symbols. Henry Dreyfuss designed this sourcebook to be as practical and easy to use as possible by arranging the symbol information within ingeniously devised sections: Basic Symbols represents a concise and highly selective grouping of symbols common to all disciplines (on-off, up-down, etc.). Disciplines provides symbols used in accommodations and travel, agriculture, architecture, business, communications, engineering, photography, sports, safety, traffic controls, and many other areas. Color lists the meanings of each of the colors in various worldwide applications and cultures. Graphic Form displays symbols from all disciplines grouped according to form (squares, circles, arrows, human figures, etc.) creating a unique way to identify a symbol out of context, as well as giving designers a frame of reference for developing new symbols. To make the sourcebook truly universal, the Table of Contents contains translations of each of the section titles and discipline areas into 17 languages in addition to English.
