This textbook is designed for students majoring in technical and scientific fields, but would be useful to students in any major and would also serve as a resource guide for professional and technical writers. The text includes writing samples illustrating the writing demands in a cross-section of career fields. Major changes to the fifth edition include coverage of the expanded role of the technical writer, with extensive coverage of the ethical and legal concerns in communication; expanded discussion of collaborative writing; additional material on the international/multicultural aspects in technical communications; a new chapter on website design and management; and the addition of 38 new illustrative graphics and page design options.
