The president of LIBER, Kristiina Hormia-Poutanen, calls on other libraries and institutions to sign the statement:

"LIBER believes that open access to publications is one of the building blocks of Open Science. Whilst much progress has been made in increasing the availability of open access publications e.g. through institutional and funder mandates, library services to support open access, and infrastructure such as OpenAire, clarity around the cost of open access publishing and publishers’ policies relating to green open access is becoming a growing concern. Without clear and immediate action to address this we risk facing a crisis of sustainability in the near future."

The National Library of Sweden (KB) has signed the statement. LERU also calls upon all universities in Europe to sign the statement.
