Citation-File Projects (2026-05-08)

Every GitHub repository known to publish a CITATION.cff or CITATION.bib file as of 2026-05-08. The Citation File Format (CFF) is a community standard that lets software authors declare exactly how they want their work to be cited — author lists, DOIs, version, release date, related preferred citations. A repository that ships a CITATION file is making an explicit, machine-readable statement: this is research software, and here is how to credit it. This portfolio is a snapshot of that population: roughly 47,000 repositories spanning the long tail of scientific computing — niche domain tools, dissertation code, lab software, individual researcher libraries, and the well-known frameworks alongside them. Together they offer a view of research software practice that does not depend on package-registry presence, citation in a journal, or membership in a foundation: it captures everyone who took the time to say "please cite me this way." Built from the latest citation-file index, normalized to one canonical GitHub URL per repository.
