A saved paper can outlive the version of the record it represents. Corrections, retractions and other editorial notices may be issued after download, and their implications differ. A useful source check locates the current article record, follows its notices and reads what changed before repeating a finding.
Start with the exact publication record
Use the DOI, PMID or full bibliographic details to locate the intended article. A similarly titled paper, a review that cites it or a duplicate search result can otherwise lead the check away from the actual source.
Open the publisher’s current article page and inspect visible update links or notices. Compare it with the version saved locally rather than assuming the PDF contains events that occurred after it was downloaded.
Crossref describes Crossmark as a way to inspect a record’s current status, including linked corrections, retractions and updates. It also explicitly cautions that the presence of Crossmark is not a guarantee.Crossref — Crossmark (opens in a new tab)
Read what the notice actually says
| Question | What to establish |
|---|---|
| Which article is affected? | Match identifiers and bibliographic details |
| What type of update is it? | Correction, retraction, concern or another change |
| Which content is affected? | Specific data, figure, method, text or whole report |
| What interpretation changes? | Whether the claim being cited still has support |
| What replacement exists? | Revised file, corrected figure or linked record |
In an original hypothetical case, one correction fixes an author affiliation while another replaces a figure legend that had reversed group labels. Those notices have different consequences for interpreting the experimental result.
Do not assume that a correction invalidates every finding. Conversely, a notice described briefly as minor on another website should not substitute for reading the actual affected content.
A retraction should remain visible in any discussion of the withdrawn record. Its data should not continue to be presented as ordinary supporting evidence without explaining the status and the purpose of discussing it.
Use another source when the status remains unclear
Crossref’s Retraction Watch documentation describes a database of retractions drawn from publisher records and other discovery routes. It notes that included corrections and expressions of concern are less comprehensive than retractions.Crossref — Retraction Watch (opens in a new tab)
A missing correction in that database therefore does not establish that no correction exists. Check the publisher record and any linked bibliographic notices, especially when a saved source conflicts with a current summary.
Search the exact title or identifier with the relevant notice term if the article page is unclear. Preserve mismatched identifiers or broken links as unresolved observations rather than guessing which paper a notice refers to.
Comments, public allegations and formal editorial notices are different records. They may warrant investigation, but label each accurately and do not infer misconduct or an editorial verdict from an unsupported claim.
Revise the evidence note transparently
Record the article version, status-check date, notice identifier and the content affected. If the correction changes a number used in your summary, update the number and its interpretation together.
In the hypothetical reversed-label case, changing a figure caption without reconsidering which group had the higher response would leave the central interpretation wrong. The task is to follow the scientific consequence, not merely add a link.
If the available notice does not resolve the issue, state what remains uncertain. An expression of concern should not be rewritten as either a completed exoneration or a completed retraction unless the later record supports that description.
Keep a traceable record of the change for future updates. A source check describes the status available at that time; it is not a promise that the publication record will never change again.
