We are Crossref, a not-for-profit membership organization for scholarly publishing working to make content easy to find, link, cite and assess. We do it in five ways: rallying the community; tagging the metadata; running a shared infrastructure; playing with new technology; and making tools and services to improve research communications.

It’s as simple—and as complicated—as that.
