A promise

Joining Crossref is a promise to look after your content. For our part, we promise to maintain and develop the community infrastructure for the long-term.

Membership therefore comes with a bit of work on your end. Crossref members make every effort to improve the quality and completeness of metadata. Once you’re in, we give you a prefix for your DOIs (Digital Object Identifiers), you create the suffixes and you begin to register content with us.

You do this by regularly depositing metadata that includes persistent identifiers and comprehensive information about the content. Your work to create and maintain the metadata is ongoing.

Not all DOIs are made equal

There are many other DOI registration agencies that are members of the International DOI Foundation. But no other DOI registration agency offers the broad range of infrastructure and services that specifically support scholarly content. Others specialize in a particular region or language or content type. Or even totally different industries such as construction, or movies. And no one else does it quite like us, either.
