“The foundation requires that any publication based on a DDCF-funded research project must be made freely available and downloadable online in a timely manner and with as few restrictions as possible, in order to ensure that DDCF-funded research can be accessed, read and built upon. Starting with grants made in 2013, DDCF grantees and their institutions must agree to fulfill this requirement by depositing all documents accepted for publication resulting from their DDCF-funded research project into the National Institutes of Health’s PubMed Central (“PMC”) in accordance with the following stipulations:
? Documents are defined to include all authors’ final manuscripts accepted for publication, including all modifications from the publishing and peer review process (the “postprints”);
? Documents are to be deposited in PMC upon the grantee’s receipt of notification of acceptance for publication;
? Grantees may impose an embargo on PMC’s public release of the documents that ends no later than 12 months after the official date of publication. 8 Access to PMC is made available to the grantee through DDCF’s membership in the Health Research Alliance (HRA) (a national consortium of non-governmental, nonprofit funders of biomedical research and training) and DDCF’s registration of data about its clinical research grants in the HRA reporter database. DDCF will provide detailed instructions for depositing documents in PMC to grantees upon DDCF’s receipt of a fully executed grant agreement.”
