Uncorrected Proof Copies and Advance Reading Copies

An uncorrected proof copy is a printing of a book made before publication so that reviewers, booksellers and the trade can read it early. It usually comes in plain or simply printed paper wrappers with a statement such as "Uncorrected Proof Copy" on the front. Proofs and advance reading copies (ARCs) are not first editions, but they come before them, and for the right title that makes them some of the most sought-after copies of all.

What proofs and advance copies are

Before a book is published, the publisher needs people to read it: reviewers, so that reviews appear on publication day; booksellers, so they order in quantity; and other writers, for quotations on the jacket. Proofs are how it does that. They are printed in small numbers, often a few hundred, and sent out weeks or months ahead.

The main kinds you will meet:

• Galley proofs: long sheets or loose pages of typeset text, used by the author and editor for corrections. Rarely seen outside archives.
• Uncorrected proofs (bound proofs): the text bound in plain or lightly printed wrappers, taken from type that has not yet had its final corrections. Often marked "Uncorrected proof" and "Not for sale".
• Advance reading copies (ARCs): often a later and glossier promotional printing, with the finished cover art, sometimes with a letter from the editor or marketing details on the back.
• Review copies: finished copies of the published book sent to reviewers, often with a printed slip giving the publication date and price. These are first editions with a slip loosely inserted, not proofs.

Publishers use these terms differently from one another, and even between imprints, so trust what is printed on the copy rather than a seller's label.

How a proof differs from the first edition

A proof was printed to be read, not sold, and it shows. Check these points:

Feature	Uncorrected proof or ARC	First edition
Binding	Paper wrappers, sometimes plain	The publisher's finished binding, hardback or paperback
Cover	Plain, a draft design or the final art	The final jacket or cover
Wording	"Uncorrected proof", "Advance reading copy" or "Not for sale"	The published price and barcode
Text	May contain errors, cuts or passages later revised	The corrected text
Preliminary pages	May differ: different author credit, missing dedication, provisional dates	Final title and copyright pages
Number printed	Usually a few hundred	The first print run, often thousands

Because the text was not final, a proof can preserve readings that never appeared in print. Collectors and scholars compare proofs with the published text to see how a book changed in its last weeks. That makes the points of issue of a proof different from those of the first edition: you are checking it against itself, not against later printings.

A review copy, by contrast, is the first edition. If you have a published hardback with a review slip, use our guide to identifying a first edition and check the number line as usual; the slip is a pleasant extra that some collectors pay a little more for.

When proofs become collectable

Most proofs are worth very little. Publishers send out proofs for every book they hope will sell, and most books never become collectable. A proof follows the fortunes of its title: if the book becomes a classic, the few hundred proofs printed before anyone knew become scarce, early and textually interesting all at once.

The proofs collectors chase tend to share some features:

• A debut or early book by an author who became important, when the publisher printed few proofs because nobody yet knew.
• Textual or design differences from the published book that make the proof a distinct object.
• Scarcity, with fewer proofs printed than first editions, and many thrown away by reviewers.
• Condition, since paper wrappers crease, fade and tear easily.

Print runs matter too. The bookseller Ken Lopez, who has handled proofs for decades, notes that plain proofs were typically printed in runs of around 200, while glossier promotional copies could run to 500 or more. A plain early proof is therefore usually scarcer than a later illustrated ARC of the same book, and collectors tend to prefer it.

Condition is judged on the same scale as any other book, but expectations are lower: a proof was a working copy, passed between readers and rarely looked after. A clean, unmarked proof with bright wrappers is the exception, and it is priced as one. Reviewers' notes inside can add interest if the reviewer is known, but anonymous scribbles count as faults.

The most famous British example is the proof of Harry Potter and the Philosopher's Stone. Bloomsbury has suggested about 200 copies were printed in 1997 for reviewers and booksellers. They are bound in plain wrappers and credit the author on the title page as "J.A. Rowling", an error corrected before publication; the copyright page reads "Joanne Rowling". Recorded sales show how prices vary with the details:

• Bonhams, 1 December 2021: a proof with the separate proof sheet of the early cover design sold for £35,250 including premium.
• Bonhams, 14 November 2023: a proof with some foxing sold for £14,080 including premium.
• Bonhams, 2024: a proof signed and inscribed by J.K. Rowling to an early supporter sold for £35,840, and her matching proof of Prisoner of Azkaban, one of 50 reported, made £23,040.

Compare those with the 1997 Bloomsbury hardback first edition and you see why proofs are now collected as a category of their own. Our Harry Potter hub covers the published editions.

How to identify a proof or ARC

Work through the copy from the outside in:

1. Front wrapper: look for "Uncorrected proof", "Proof copy", "Advance reading copy" or "Not for sale".
2. Back wrapper: ARCs often carry a publication date, price, print run or marketing plan. Proofs may be blank.
3. Title and copyright pages: note any differences from the published book, such as a variant author credit, provisional dates or a missing dedication.
4. Text: if you know the published book, spot-check passages known to have changed.
5. Inserts: a publisher's letter or review slip is part of the copy's story; keep it with the book.

A valuable proof is worth faking, and plain wrappers are easy to imitate, so compare a copy with a described example before paying a serious price. Buy significant proofs from dealers who describe them precisely and guarantee what they sell.

Can you sell a proof marked "Not for sale"?

Many proofs and ARCs carry "Not for sale" on the cover. That wording records the publisher's intention that the copy is promotional, and some reviewers and booksellers receive copies under terms that ask them not to resell.

In practice, proofs of collectable books are openly sold by established rare book dealers and by major auction houses, including Bonhams and Sotheby's in London. In the United States, an appeals court ruled in 2011, in UMG Recordings v. Augusto, that promotional music CDs labelled for promotional use and sent out unsolicited had been transferred to the recipients, who could therefore resell them. That case concerned music, not books, and is not UK law.

The general position is that the answer can depend on how the copy was supplied and on the law where you are. If you received proofs directly from a publisher under an agreement, check its terms before selling. This guide is general information, not legal advice.

Check your copy

Find the published book on Browse, then compare your copy's wrappers, title page and copyright page with the first edition listed there. If you think you have an early proof of a collectable title, keep it flat, out of the light and in a protective sleeve, and record any inserts with it before you look at selling. Our guide to signed and inscribed books covers proofs that the author has also written in.
