Comparison
Crossref vs OpenAlex
Who’s behind each, what their homepages track, what they cost and how often their policies changed, measured the same way for both. By what they offer, they’re very close.
Crossref is a nonprofit DOI registration agency that lets publishers, funders and research institutions register persistent identifiers and metadata for scholarly works, and shares that metadata openly through free APIs for citation and reference linking.
OpenAlex is a free, open bibliographic database that indexes scholarly works along with their authors, institutions, journals and topics. It can be searched through a web app, an API and bulk data downloads.
