Frequently Asked Questions

Does ezbib require an ORCID API key or account? No. Public ORCID profiles are queried directly through the public ORCID REST API v3.0, and DOI metadata is resolved via Crossref content negotiation without requiring an API key.

What happens if an ORCID publication has no DOI? If a work in the ORCID record does not have an attached DOI, ezbib outputs a clear commented placeholder in the BibTeX file: % Work without DOI: Title of Publication (Year) This ensures no entries are silently dropped while keeping your .bib file syntactically valid.

How does preprint deduplication work? Preprints (identified by journal titles containing arxiv, biorxiv, chemrxiv, research square or type PREPRINT) are fuzzy-matched against peer-reviewed articles in the same ORCID profile. If a published journal version exists, the preprint is automatically suppressed unless --no-dedup is specified.

Can I format citations in styles not listed above? Yes. Any valid CSL (Citation Style Language) style identifier supported by the Crossref citation service can be passed directly to --style (e.g. --style cell, --style pnas).
