- dragon book — (publication) The classic text "Compilers: Principles, Techniques and Tools", by Alfred V. Aho, Ravi Sethi, and Jeffrey D. Ullman (Addison-Wesley 1986; ISBN 0-201-10088-6). So called because of the cover design featuring a dragon labelled "complexity of compiler design" and a knight bearing the lance "LALR parser generator" among his other trappings. This one is more specifically known as the "Red Dragon Book" (1986); an earlier edition, sans Sethi and titled "Principles Of Compiler Design" (Alfred V. Aho and Jeffrey D. Ullman; Addison-Wesley, 1977; ISBN 0-201-00022-9), was the "Green Dragon Book" (1977). (Also "New Dragon Book", "Old Dragon Book".) The horsed knight and the Green Dragon were warily eying each other at a distance; now the knight is typing (wearing gauntlets!) at a terminal showing a video-game representation of the Red Dragon's head while the rest of the beast extends back in normal space.
