A foreword, according to the Chicago Manual of Style, is usually written by someone other than the author. A foreword is like a stamp of approval on the book, and it helps publishers to market the book, particularly if an already-established author writes it. A foreword ranges from one to two pages. By the way, people often misspell “foreword” as “foreward” or “forward.” To remember the correct spelling, think of a foreword as the “word” that comes be“fore” the book.
A preface, which the author writes, is about the book itself. A preface often explains how the author wrote the book or why. A preface can also establish the author’s credibility to write about a topic. The goal of the preface is to draw in the audience and persuade them to read the book.
An introduction does exactly what the name implies: the author introduces the audience to the book’s content. An introduction may explain the book’s organization or its overall themes. If the author researched a topic, then the introduction may define terms or describe the methodology.
What comes first? If a book has all three opening sections, then the foreword is first, the preface follows, and third comes the introduction.
Oh, and my project? All that content ended up in an introduction, not a preface or foreword.
