Abstract:

The elements of technical writing includes a basic definition of technical writing--'writing about subjects in technical disciplines'--as well as a high-level outline of the book. Few prefaces contain as thorough a summary of changes as Pearsall offers. The summary of changes in this second edition acknowledges the necessity for current information in the changing technical writing arena, listing several specific changes from the first edition.
