Book excerpt: This compact but complete guide shows that less is more—with fewer extraneous details getting in the way of students trying to learn on the run, it allows them to focus on the most important principles of effective technical communication. The Concise Guide takes a rhetorical approach to technical communication; instead of setting up a list of rules that should be applied uniformly to all writing situations, it introduces students to the bigger picture of how the words they write can affect the people intended to read them. Assignments and exercises are integrated throughout to reinforce and test knowledge.
