foreword

n. preface, introduction, prologue

Not to be confused with the relative direction of "forward."A foreword is a short (or long) piece of writing often found at the beginning of a book or other piece of literature, before the introduction, and written by someone other than the author of the book. A preface, by contrast, is written by the author of the book, although sometimes the two terms are used interchangeably. A preface generally covers the story of how the book came into being, or how the idea for the book was developed; this is often followed by thanks and acknowledgments to people who were helpful to the author during the time of writing. Often, a foreword will tell of some interaction between the writer of the foreword and the story or the writer of the story. A foreword to later editions of a work often explains in what respects that edition differs from previous ones.
