ARC vs galley: what is the difference?
- Both are pre-publication copies of a book.
- A galley is an early typeset proof, often unproofed.
- An ARC is a near-final advance copy for reviewers.
- The terms overlap and are sometimes used interchangeably.
- Both go out before the finished book to generate early reviews.
A galley and an ARC are both pre-publication copies, with a subtle distinction. A galley (or galley proof) traditionally refers to an early typeset version used for proofreading and early review, often still containing errors. An ARC (advance reader copy) is a more polished, near-final copy distributed to reviewers, booksellers, and influencers to generate early buzz and reviews. The terms overlap and are often used interchangeably today, but both serve the same core purpose: getting the book to early readers before publication.
Chapter i·Why it matters
Authors and publishers encounter both terms in the pre-publication and review process, and understanding them clarifies how early-review distribution works. Knowing that galleys and ARCs are pre-publication copies sent to generate reviews and buzz — and the subtle difference in their typical stage of polish — helps authors navigate ARC campaigns and reviewer outreach. It is basic publishing vocabulary for the crucial pre-launch period when early reviews are built.
Chapter ii·What to include
- Both as pre-publication copies.
- A galley as an early typeset proof.
- An ARC as a near-final reviewer copy.
- The overlapping, interchangeable usage.
- Their shared purpose: early reviews.
- Their role in the pre-launch process.
Chapter iii·Example
A publisher sends out galley proofs early for trade review and proofreading, then distributes polished ARCs to its reviewer list and booksellers closer to publication. Both are advance copies generating early reviews and buzz; the galley is the rougher, earlier proof, the ARC the near-final reader copy. The author understands both as pre-launch review tools.
