Paste any scholarly identifier - DOI, PubMed ID, PMCID, arXiv ID, ADS bibcode, or paper URL. We resolve it to the right form and check for retractions, corrections, and expressions of concern via Crossref + Retraction Watch.

We’ll check for retractions, corrections, and expressions of concern via CrossRef + Retraction Watch. Nothing is stored.
Each result shows a status badge, the paper title, and any retraction or correction notices on file.
Cortical oscillation patterns during sustained attention in early development
No retractions, corrections, or expressions of concern found for this DOI.
Reproducibility of amyloid-beta aggregation kinetics under variable pH conditions
Stimulus-triggered acquisition of pluripotency in mammalian cells
A retraction is a formal withdrawal of a published paper by the journal or the authors. It means the findings are no longer considered reliable - usually because of errors, data fabrication, plagiarism, or ethical violations. Retracted papers remain in the database but are marked so that readers and citers know the work has been disavowed.
Retractions are distinct from corrections (errata or corrigenda), which fix specific errors without withdrawing the paper, and expressions of concern, which signal that an investigation is underway but no final determination has been made.
See the retraction entry in our glossary.
You can enter any scholarly identifier. If you enter a DOI, the tool checks CrossRef directly. If you enter a PMID, PMCID, arXiv ID, or ADS bibcode, the tool first resolves it to a DOI, then checks CrossRef. If no DOI can be found, the tool will let you know.
This tool uses retraction data from the Retraction Watch database, which is integrated into CrossRef. When a paper is retracted, corrected, or flagged with an expression of concern, CrossRef adds the notice to the paper’s metadata. This tool reads that metadata and presents it in a clear format.
Retraction and citation authenticity are two different signals. A retraction check asks has this real paper been withdrawn? A citation authenticity check asks does this citation actually refer to a real paper at all? Both matter, and a citation can fail either test.
If you suspect an AI assistant invented a citation - a real-looking DOI paired with a title that does not appear when you search for it - use the citation verifier. It resolves the identifier and compares the resolved title to the claimed title, flagging the dominant fabrication pattern documented by Topaz et al. (Lancet 2026). See citation integrity in the age of AI for the broader context.
The retraction notice may not yet be indexed in CrossRef, or the paper’s publisher may not have registered the retraction with CrossRef. Retraction Watch data is integrated into CrossRef on a rolling basis; very recent retractions may take some time to appear.
Generally yes - corrections fix specific errors without invalidating the paper. But read the correction notice to understand what changed. If the correction affects a finding you are relying on, note it in your citation.
Yes. No account required. Nothing you enter is stored. The underlying data comes from CrossRef and Retraction Watch, both of which are freely accessible.
If no retractions are found, format and export the citation using the citation formatter, BibTeX, or RIS.
