How do Copyediting, Proofreading compare side by side?

The table below compares Copyediting, Proofreading across 9 procurement-relevant dimensions, from what it checks through what follows it.

Side-by-side comparison

DimensionCopyeditingProofreading
What it checksGrammar, spelling, punctuation, house-style/citation-format compliance, and internal consistency (terminology, abbreviations, units, figure/table numbering).Typographical errors, missing or duplicated text, misplaced figures/tables, incorrect running heads or page numbers, and whether copyediting corrections were correctly inserted into the typeset proof.
When it happensAfter peer review and the editorial acceptance decision, on the accepted manuscript — before typesetting/layout.After typesetting/layout, on the page proofs (PDF galleys or HTML/XML output) — the final step before publication.
Performed onThe manuscript text itself (the author-accepted manuscript).The typeset proof — final pagination, fonts, and figure placement already applied.
Depth of change permittedCan correct and standardize text, and query the author about unclear passages, but does not restructure the argument or content.Surface-level only — corrects errors; not the place to introduce new substantive edits or rewrite text.
Style-guide roleApplies and enforces the journal/publisher house style (e.g., AMA, APA, or Chicago) throughout the manuscript.Confirms the applied style survived typesetting correctly; does not apply new style rules.
Who performs itA copyeditor on the journal or publisher’s production team (in-house or a contracted vendor).A proofreader (sometimes the same person as the copyeditor, sometimes a separate specialist), plus the author’s own proof review.
Relationship to peer reviewHappens strictly after peer review and acceptance; never applied to a manuscript still under review.Happens well after peer review has concluded, at the very end of production.
Author’s roleResponds to copyeditor queries about ambiguous or unclear passages.Reviews the page proof and reports remaining errors within a short turnaround window (often 48–72 hours).
What follows itTypesetting/layout.Publication as the version of record (VoR).

Common questions

Common questions about Copyediting vs Proofreading

Is copyediting the same as proofreading?

+

No. Although the two terms are sometimes used loosely and interchangeably outside of publishing, in a journal production workflow they are distinct stages with different scope and timing: copyediting is the earlier, deeper edit for grammar, style, and consistency on the manuscript; proofreading is the later, lighter check for remaining errors on the typeset proof.

Does copyediting happen before or after peer review?

+

Production copyediting happens after peer review and after the editorial acceptance decision — it is applied to the accepted manuscript, not the version still under review. Some authors separately pay for author-side language editing before submission, but that is a different, pre-submission service.

Can proofreading catch a factual or scientific error?

+

A proofreader can notice one, but fixing it is not what proofreading is for. Substantive errors identified at the proof stage are typically handled through an author query and editorial sign-off, or after publication through a formal correction/erratum process, rather than a free rewrite of the proof.

Who pays for copyediting and proofreading in academic publishing?

+

Production copyediting and proofreading are normally performed by the journal or publisher’s own production team as a standard part of the publication process, at no separate cost to the author. That is distinct from author-side, pre-submission language-editing services, which authors who choose to use them pay for separately before submission.
