Foreword vs preface vs introduction: what goes where

A foreword is the only part of a book written by someone other than the author. Its job is borrowed credibility: an expert, a well-known name or someone with standing in the subject introduces the author and vouches for the work. It is signed, usually with the writer's name and sometimes place and date, and it always ends before the author's own voice begins. In non-fiction, a strong foreword from the right name genuinely moves sales; in fiction it is rare outside anniversary editions and classics.

And the spelling matters more than it should: it is foreword — the word before — not 'forward'. Misspelling it on a contents page is one of the quiet tells of a hastily produced book, worth catching before your files reach the printer.

A preface is the author speaking about the book rather than in it: why you wrote it, how it came to be, what changed in the second edition, what the reader should know before starting. It is the book's backstory told in your voice, it is signed by you (often with place and year), and it is far more at home in non-fiction and memoir than in novels — fiction readers want the story, not the story of the story.

The test for whether material belongs in a preface is simple: could the reader skip it and still fully understand the book? If yes, it is preface material. If no, it belongs in the introduction — or in chapter one.

An introduction is part of the book proper: it sets up the subject, defines terms, explains the structure and tells the reader how to use what follows. Skip it and you miss content — that is what distinguishes it from a preface. In many non-fiction books the introduction is effectively chapter zero, and unlike forewords and prefaces, which sit on roman-numeral pages, an introduction often starts the arabic page numbering because it belongs to the text itself.

Most non-fiction books need an introduction and nothing else. The full stack — foreword, preface and introduction — is for books that have genuinely earned all three: a name lending authority, an origin story worth telling, and a subject that needs framing. Piling all three onto a first book mostly delays chapter one.

A prologue is fiction's opening gambit — a scene from before the main story, another point of view, a glimpse of the crime or the war to come. It is story, written in the book's own voice, which is why it sits after the front matter and on page one's side of the divide. Its mirror, the epilogue, closes the frame after the final chapter. The honest test of a prologue is whether it would survive being renamed 'chapter one'; if it is only throat-clearing, cut it.

An epigraph is the short quotation — a line of poetry, scripture or borrowed wisdom — set alone on a page or under a chapter heading to tune the reader before the text begins. It needs no label and no explanation, though quoting living writers' work (and any song lyric) can require permission, which is worth checking before it is printed in every copy.

The conventional running order: half-title (title alone), title page, copyright page on its reverse, dedication, epigraph if you have one, table of contents, foreword, preface, acknowledgements (which can equally live in the back), and then introduction — with the story or subject beginning on a fresh right-hand page. Front matter traditionally takes roman numerals, switching to arabic 1 where the book proper starts. No book uses every slot; most self-published books need only title, copyright, dedication and contents.

Each of those pages has its own conventions, covered across our front-matter guides: what goes on the copyright page, how to write a dedication, and the author bio that usually closes the book. Get the order right in your interior file before typesetting — reshuffling front matter after layout renumbers everything behind it.
