“It is essential…to understand the differences between the foreword, preface, and introduction of a book. Each section plays a vital role in the critical and financial success of the book. Without these three sections, a non-fiction book is incomplete, and not giving the readers their money’s worth…
1. The Foreword (Why the reader should read the book)
The foreword is the place for a guest author to show the reader why they should be reading this book.
2. The Preface (How the book came about)
The preface is a place for the book’s author to tell the reader how this book came into being, and why.
3. The Introduction (About the content of the book)
The introduction introduces the material that is covered in the book.”
