Under Horizon 2020, each beneficiary must ensure open access to all peer-reviewed scientific publications relating to its results.In order to comply with this requirement, beneficiaries must, at the very least, ensure that their publications, if any, can be read online, downloaded and printed. However, as any additional rights such as the right to copy, distribute, search, link, crawl, and mine increase the utility of the accessible publication,
beneficiaries should make every effort to provide for as many of them as possible.
