The document summarizes a message from the Commissioner for Culture and Education at the German Federal Foreign Office regarding open access. The commissioner notes that open access is now an important issue on the European political agenda. He welcomes an initiative by the German Commission for UNESCO to publish a handbook about open access to draw public attention to its opportunities and challenges. Given the complexity of issues and variety of participants in the open access debate, wide-ranging discussion is needed. The commissioner is grateful to all those involved in the workshop that helped develop the idea for the handbook.
