Preface
Since you are taking the time to read this preface， you are probably standing in a
bookstore， surrounded by shelves of computer books， trying to decide which one to
buy. The function of this preface is to explain the concept of this book to help you
make that decision.
There are three ideas that sum up the approach used in teach yourself...Harvard
Graphics， which I believe make it different from most books about software
applications.
Education. The purpose of this book is to help you learn to use Harvard Graphics.
All learning takes place through a structured experience that guides you through a
working session with the program where you will discover for yourself the concepts
behind the command structure of the program.
In.Context Examples. The examples given in the book are complete keystroke-for-
keystroke lessons. This means the features and techniques are explained within the
context of an actual project. This is very important when you are trying to learn to
use a program well， because it reveals not just how the features work， but how they
work with each other.
Visual Reinforcement. This book contains more than 150 illustrations. The
illustrations are an important part of learning. They show how charts and drawings
are constructed， step-by-step， and serve as a point of reference for comparing your
results to those in the book.
From my experience of writing 28 computer books since 1983， I have found that the
detailed， step-by-step method used in this book is the best way to learn and
understand a new software application. This method not only allows you to get
started with the program， but also encourages you to continue learning after you have
finished the material in the book，
