Direct comparison
Preprint vs published article — what is the difference?
A preprint is a manuscript shared publicly before peer review; the published article is the peer-reviewed version of record. They are often the same underlying work at different stages, and most funders accept either as a route to open access.
Side-by-side comparison
| Dimension | Preprint | Published article |
|---|---|---|
| Peer-reviewed? | No — posted before formal peer review | Yes — peer-reviewed before publication |
| Where it lives | Preprint server (arXiv, bioRxiv, medRxiv, SSRN) | Journal — publisher's platform |
| Status | Early, citable, may still change | Version of record — canonical, fixed |
| Speed | Immediate — available within days | Slower — weeks to months of review |
| Identifier | Often a DOI (e.g. via DataCite or the server) | DOI via the publisher (usually Crossref) |
| Copy-editing / typeset | No — author's own formatting | Yes — copy-edited and typeset by the journal |
| Certification | None — readers judge the work themselves | Journal certifies via peer review |
| Open-access route | Counts as Green OA at many funders | Gold / Diamond / Hybrid depending on the journal |
| Versioning | May have several versions; can be superseded | Stable; corrections issued as errata |
Common questions
FAQ
Is a preprint the same as the published article?+
Usually it is the same underlying work at an earlier stage. The preprint is posted before peer review; the published article is the reviewed, copy-edited version of record. Content can differ where peer review prompted changes, so the published version is the one to cite as canonical.
Can I cite a preprint?+
Yes — preprints are citable and most carry a DOI. Make clear it is a preprint (not peer-reviewed) and, if a peer-reviewed version of record later exists, prefer citing that.
Do preprints satisfy open-access mandates?+
Often yes. Depositing the manuscript as a preprint or accepted manuscript is the "Green" open-access route and is accepted as one compliant pathway by many funders, including under Plan S, provided the licensing and timing conditions are met.
Does a preprint count against journal publication?+
For most journals, no — the majority allow prior preprinting. A minority have restrictions, so it is worth checking the journal's preprint policy before submitting.
