Three year read and publish agreement signed with VTT IOP Publishing (IOPP) has signed its first open access (OA) transformative agreement in Finland. The three year ‘read and publish’ agreement with the VTT Technical Research Centre of Finland (VTT) enables the institution’s authors to publish open access in 58 hybrid IOPP and partner journals at no cost to authors at point of publication. Articles will be published under an open licence (CC-BY), allowing authors to retain copyright. As well as barrier-free publication, researchers and students at VTT will have reading access to all IOPP journals. Owned by the Finnish state, VTT is one of Europe’s leading research institutions. They advance the utilisation and commercialisation of research and technology in commerce and society.
