As appeals for public access of research data continue to proliferate, many scholarly publishers-alongside funders, institutions, and libraries-are expanding their role to address this need.

This call to action emerged from a summit that brought together data stewardship leaders across stakeholder groups. The recommendations were subsequently refined by the community as a result of public input gathered online and in meetings.
