Full agreement texts for academic publisher agreements. The agreements were released by the FinELib consortium of research libraries following our FOI request in April 2018.

Scientific journal subscription costs in Finland 2010-2017; MoE/ATT. The data set was released by Finnish Ministry of Education (Open Science and Research Initiative) following my Freedom of Information Request (summary). Finland became the first country to systematically collect and release this information.
