Their Open Access policy is designed to improve access to the results of Agency-funded research, and to increase the dissemination and exchange of research results. Recipients of these grants are required to ensure that any peer-reviewed journal publications arising from Agency-supported research are freely accessible within a year of publication. To do this, grant recipients can either add the final, peer-reviewed manuscript to an institutional or disciplinary repository that will make the manuscript freely accessible within a year of publication; or recipients can publish in a journal that offers immediate open access or that offers open access on its website within a year. The Tri-Agencies strongly encourage recipients to add their manuscripts to an open access online repository immediately upon publication.
