Some small organisations who want to register metadata for their research and participate in Crossref are not able to do so due to financial, technical, or language barriers. To attempt to reduce these barriers we have developed several programs to help facilitate membership. One of the most significant—and successful—has been our Sponsor program.
Sponsors are organisations that are generally not producing scholarly content themselves but work with or publish on behalf of groups of smaller organisations that wish to join Crossref but face barriers to do so independently. Sponsors work directly with Crossref in order to provide billing, technical, and, if applicable, language support to Members.
