Citation Verification
Check citations for retracted or corrected records, reachable links, and required metadata fields, and see whether each source can be found in the scholarly indexes we search. Results are prompts for review, not proof that a citation is correct.
What We Check
Retracted Papers
When a DOI is available, we query supported scholarly metadata sources for retraction or correction records. A check may be skipped when a source cannot be identified or a provider is unavailable.
Broken Links
When a URL is available, we test whether it can be reached. A reachable link does not confirm the source metadata or content is correct.
Missing Fields
We check for metadata fields required by the selected citation style, such as authors, dates, or titles. This check does not evaluate punctuation, capitalization, or complete formatting.
Source Records
We look for each source in Crossref, DataCite, Open Library and OpenAlex, and compare its title, year and authors with the record. A source that is not found is not marked as wrong: many real books and reports are listed nowhere.
How It Works

We Analyze
The system runs the applicable retraction/correction, link, required-field, and source-record checks. Some checks may be skipped when they cannot run.
Review Results
Review detected issues, skipped checks, and available suggestions before deciding whether to edit the citation.
