¹ú²úÂÒÂ× offers a free open access support service to make it easier for our authors to discover and apply for funding to cover article processing charges (APCs). In addition to our list of funding sources for OA publication costs, we have a number of additional resources to help authors learn about APC funding. We also provide guidance to help authors understand and meet their funders’ and institutions’ OA policy requirements when publishing in ¹ú²úÂÒÂ× journals.
