Tools & capabilities

Opencitations tools 6

  • references"What does paper [DOI] cite" / "references in [paper]" / "what sources does this paper use" — DOIs cited BY the given DOI (the paper's reference list / bibliography). Use for citation-graph traversal, literature review, source tracking.
  • citations"Who cites paper [DOI]" / "what papers reference [DOI]" / "incoming citations to [paper]" / "what work has cited [study]" — DOIs that CITE the given DOI (reverse-direction from references). Use for impact analysis, follow-on research discovery, "is this paper influential" questions.
  • citation_count"How many times has paper [DOI] been cited" / "citation count for [paper]" / "is [study] highly cited" — incoming citation count for a DOI. Fast version of `citations` when you only need the number, not the citing DOIs.
  • references_count"How many references does paper [DOI] have" / "how big is the bibliography of [paper]" — outgoing reference count for a DOI. Fast version of `references` when you only need the number.
  • metadata"Get paper info for [DOI]" / "bibliographic details for [paper]" / "title / authors / year of [DOI]" — bibliographic metadata for one or more DOIs (up to 50 at once). Returns title, authors, year, journal, publisher.
  • citationFetch one citation record by its Open Citation Identifier (OCI — a compound ID of the form citing-DOI__cited-DOI). Returns citing/cited DOI pair, creation date, and journal self-citation flag. Use `citations` or `references` instead when you only have a DOI.
