This text is designed to bridge the gap between research and practice, by emphasizing practice from a conceptual viewpoint. The authors discuss and review the literature on online help and they provide a cognitive perspective on the design and evaluation issues. The goal is to provide a review and analysis of the issues in the design and evolution of online help systems. The book should be of interest to those conducting research on document design and technical writing in English and psychology and in the college of engineering; interface design in computer science, psychology, and human factors; and human factors issues in government and industry labs, the defence industry, the communications industry, and the computer industry.
