Citation Generator

Generate an APA, Vancouver, Harvard, or Chicago citation from a DOI. A bounded, deterministic formatter for the common journal-article case — not a full CSL engine, and not a claim of exact compliance with every published style manual edge case.

About this tool

Purpose
Generates an APA, Vancouver, Harvard, or Chicago citation from a DOI.
Try this
Paste a real DOI and pick a citation style.
Expected result
A correctly formatted citation, ready to copy.
Privacy
Checks JCF's own data first; only when there's no match, makes a single bounded request to a public identifier-lookup provider for the one identifier you entered. Nothing you enter is stored.
Limitations
Citation accuracy depends on the underlying article metadata being complete and correct.
