Crossref: checking scholarly metadata

Crossref is a useful first stop when a citation needs a DOI, publisher record, or update trail. Its REST API serves JSON metadata deposited by members and trusted sources, with search, filters, and single-DOI lookup. The documentation states that sign-up is unnecessary.

A practical lookup starts with the DOI, then checks title, authors, dates, and update relations against the publisher record. A successful metadata match identifies a work; evaluating its conclusion still means reading the work. Crossref metadata can include abstracts, whose reuse conditions may differ from the surrounding metadata.

Documentation reviewed; no API request was tested for this page. Add a dated example if you find an ambiguous citation or a correction worth keeping.
