Printings, editions and ISBN: does a second printing need a new number?
Reprint or new edition? The distinction decides the ISBN, and it is the one publishers get wrong most often. A decision table, the imprint page, and how the hierarchy should sit in a system.
One of the most common technical questions in a press: “Does the second printing need a new ISBN?” It cannot be answered in a word, because the question rests on a vocabulary problem that most languages share.
The imprint line “2nd edition” sometimes means the same book printed again and sometimes a version whose content has changed. English has separate words for these — impression (or printing) and edition — but they are used loosely enough in practice that the ISBN decision gets muddled with them. In Turkish the two share a single word entirely, which makes the confusion structural rather than careless.
This piece separates three concepts and gives the decision table.
Three separate concepts
Printing (impression). The same book, same content, same format, printed again. Stock ran out; another thousand were run. The product has not changed.
Edition. A version whose content has substantially changed: a chapter added, text updated, a preface written, legislation revised. From the reader’s point of view this is now a different product.
Format. The same content in a different physical or digital shape: paperback, hardback, ebook, audiobook. Same content, different product.
The key to the rule sits here: an ISBN identifies a product, not a work. When a reader or a library orders an ISBN they must know exactly what will arrive. So the question is never “did the content change” but “did the product the buyer receives change”.
The decision table
| Situation | New ISBN? |
|---|---|
| Same content, new print run | No |
| A few typographical corrections | No |
| Price change | No |
| New cover design, same binding | No (general rule) |
| New chapter, appendix, preface or updated text | Yes |
| Paperback to hardback | Yes |
| Print to ebook | Yes |
| EPUB and PDF sold separately | Yes — one each |
| Audiobook version | Yes |
| Reissued by a different publisher | Yes |
| Translation into another language | Yes |
The logic of international ISBN practice fits in one sentence: different formats take different numbers, because a reader who wants the hardback must not receive the paperback; substantially changed content takes a different number, because a reader who does not get what they expected will complain.
The “revised and expanded second edition” trap
This is where the mistake is made most often. The imprint says “2nd printing”, the same ISBN is reused — but two new chapters went into the content. By definition that is a new edition and it needs a new ISBN.
The consequences are invisible and real: two different books collapse into one record in library catalogues, the sales channel cannot tell which version is in stock, academic citation loses track of which printing was cited, and royalty accounting rolls the sales of two distinct products into one line.
A practical test: if you are putting a word like “revised”, “expanded” or “updated” on the imprint page, you are almost certainly publishing a new edition. If none of those words apply and genuinely nothing changed, what you have is a straight reprint.
What belongs on the imprint page
An imprint page should carry all three concepts without mixing them:
- Printing number and date — “3rd printing, March 2026” (for a reprint, the edition statement does not change).
- Edition statement — where content changed, stated plainly: “2nd edition (revised), January 2026”.
- An ISBN per format — print and ebook versions listed separately, so a reader can see which number belongs to which version.
Getting these three right keeps the book correctly represented in catalogues and sales channels for its whole life. Getting them wrong cannot be undone later: once a number is out in the distribution channels, it cannot be recalled.
One note for Türkiye: the bandrol (the state-issued banderole affixed to copies) is separate from the ISBN and runs on a different rhythm — the ISBN stays constant while the product is unchanged, but banderoles are obtained again for each new print run. We collected both formal processes in ISBN, banderole and publisher certificate.
How it should sit in a system
Modelled correctly, a book’s record carries this hierarchy:
Work (one identity: title, contributors, royalty contract) → Edition (content version: first edition, revised second edition) → Format (paperback, hardback, EPUB — each with its own ISBN and price) → Printing (run records: quantity, date, printer, banderoles)
The practical consequences are clear. Inventory is held at format level — the hardback can be sold out while the paperback is in stock. Price is a format-level attribute. Royalties live at work level and are fed by sales across every format; where the contract sets different rates per format, that distinction is drawn here too (contracts and payouts).
This structure cannot live in one table. In a spreadsheet built as a “book list”, work, edition, format and print run are all squeezed onto one row; when the second edition arrives you either open a new row (and split the royalty in two) or overwrite (and lose the first edition’s sales history). We covered the anatomy of a book record separately; this hierarchy is its spine.
The short answer
The short answer: if content and format are unchanged, a second printing keeps the same ISBN; if content changed substantially or the format changed, it needs a new one. When in doubt, ask yourself one question — would the reader who ordered this product look at what arrived and say “this is not what I expected”? If yes, take a new number.
What happens to a new print run in the warehouse and on consignment is in the inventory piece; print-run and cost decisions are in the printing piece. To set up the work–edition–format relationship in your own catalogue, book a demo.
