Identify a DOI for a Reference

Match a formatted reference and compare candidate metadata before choosing a work.

/oo Crossref: Match this reference in Crossref [reference]. Compare candidate titles, authors, publication dates, and DOI values, and explain which candidate fits or what remains ambiguous.

Prepare Citations from Known DOIs

Read work metadata and export citations for the chosen DOI and format.

/oo Crossref: Read Crossref works for DOIs [DOIs] and export each as [BibTeX, RIS, CSL JSON, or formatted citation]. For formatted output use style [style] and locale [locale]. Flag metadata that needs confirmation.

Frequently Asked Questions

Can AI help when I only have a written reference?

Yes. Supply the reference text for candidate matching and compare the metadata before accepting a DOI.

Can I export BibTeX or RIS?

Yes. Provide the DOI and requested format. Formatted citations also accept a style and locale.

Does a DOI lookup return a paper’s full text?

It returns bibliographic metadata and references to the work, rather than retrieving the complete paper text.
