Mandates and funding
Institutions, funders, societies and organizations all over the world have adopted OA mandates, encouraging or even obligating their affiliated authors to make their research and data freely available.
Some OA mandates focus on either the Green or the Gold model; others give their authors the option to choose between the two routes. ROARMAP, the Registry of Open Access Repositories Mandatory Archiving Policies, lists the open access mandates and policies of funders and research institutes in a searchable database.
To support the benefits of OA, a large number of funders and institutions have made OA part of their general funding or have created central funds dedicated to covering APCs for their researchers, faculty, or members. There are now more than 100 funds available to authors and the number continues to grow. There are also membership programs that institutions can join to financially support their affiliated researchers.
