If you don’t meet the criteria to become a member but instead want to look up metadata or add it into your own software, check out our Metadata Delivery services.
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 publishers 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.
