Peer Review on the Move from Closed to Open

Openness in peer review is no longer a terra incognita. However, there remains a need for further experimentation and careful evaluation of its advantages and disadvantages in practice. OpenAIRE, the European digital infrastructure for Open Scholarship, offers a unique environment for such experiments. This paper describes the design and early results of three such experiments, which are currently under development in close collaboration with selected publishing and repository communities.
