In order to meet our mission of a truly global and connected research ecosystem, it is important to ensure that participation in Crossref and all our services and metadata is accessible to everyone involved in documenting scholarly progress. Crossref membership is open to all organisations that produce scholarly and professional materials and content. But cost and technical capabilities can be barriers to joining, and where that’s the case, we aim to reduce these in a number of ways. These include: partnering with organisations such as the Public Knowledge Project to support plugins for OJS users; by developing our Sponsor program where members are supported by an organisation that aggregates our fees and provides local language technical support.
