This is a style guide for making decisions about layout and typography. Drawing on a variety of sources, old and new, it presents an overview and analysis of two fundamentally different typographic approaches - the traditional style that evolved over centuries from the Renaissance book, and the modern style that reflects the German-Swiss philosophy of this century. Each style is a reflection of a particular philosophy; each has its own structure and its own set of procedures, priorities and rules. Each section of the book is a model of the style it presents and includes numerous examples, old and new. The book comes with two supplemental materials - a 48-page workbook provides exercises, samples, and specifications for reproducing page samples, grids, and layouts; an 800K disk contains layout templates for traditional and modern formats.
