Moby-Dick is a classic of technical literature as well as a classic of American literature. But for the technical writing teacher, its relevance goes beyond this: Moby-Dick can also be a valuable teaching resource. It provides pertinent examples for teaching students the concepts of audience, purpose, research and sources, use of background experience, and thoroughness in compiling data. It also supplies ample models of technical definitions, descriptions, processes, and theories. Finally, Moby-Dick demonstrates the kind of energetic technical writing that is so needed today.
