Jyrki Ilva has published "Looking for Commitment: Finnish Open Access Journals, Infrastructure and Funding" in Insights.
Here's an excerpt:
Most of the 100+ Finnish scholarly journals are published by small learned societies. Since 2015, the National Library of Finland and the Federation of Finnish Learned Societies have been working on a joint project which aims to provide the journals with the support they need for making a transition to open access. The project has launched an OJS-based shared publication platform (Journal.fi), which is already used by 50 journals. It has also been developing a new funding model for the journals. Since the subscription and licensing costs paid by the research libraries for these journals have been very small, it is not possible to simply use these funds to pay for open access. Instead, the project has been working on a consortium-based model, under which the Finnish research organizations and funders would commit themselves to providing long-term funding to the journals. In return, the journals would pledge to follow strict standards in openness, licensing, peer review and infrastructure.
