Crossref makes research outputs easy to find, cite, link, and
assess.



We’re a not-for-profit membership organization that exists to
make scholarly communications better. We rally the
community; tag and share metadata; run an open
infrastructure; play with technology; and make tools and
services—all to help put scholarly content in context.
It’s as simple—and as complicated—as that.
Crossref overview
• Over 10,000 member organizations

• Metadata store of over 95 million scholarly content items

• A DOI is just the start - We offer a wide array of services
to ensure that scholarly research metadata is registered,
linked, and distributed.

• We preserve the metadata we receive and make it
available via our open APIs and Search.
Persistent identifiers
Persistent identifiers
https://doi.org/10.1006/jmbi.1995.0238
• The DOI directory: makes the DOI actionable on the web
• Prefix: assigned by Crossref
• Suffix: assigned by the publisher
Total DOI = routes through the DOI resolver to point to the registered
URL
metadata
everything, including…
author names, ORCIDs, affiliations, article titles,
ISSN, ISBN, pages, issue #, volume #s, dates,
identifiers
more metadata
such as …
reference lists, funding data, ORCIDs, license data, clinical trial
numbers, errata, retractions, updates and more through our
Crossmark service, JATS-formatted abstracts, relationships
between items…
