Intended to improve the quality of public documents by making them clearer to the people who use them, this book contains document design principles concerned with writing documents that are visually distinct, attractive, and easily understood. Following an introduction, the major portion of the book presents the 25 principles, each of which includes a guideline that explains the principle, provides examples, and offers common sense advice. The principles are divided as follows: (1) text organization, (2) sentence writing, (3) typography, and (4) graphic design. The final portion of the book summarizes some of the research that has been done on each of the principles. (HTH)
