Every year a Graphic Novel Day during the festival is organised. Since 2002, internationally renowned guest authors of the ilb have visited Berlin prisons, free of charge, for an afternoon or evening during the festival where they read from their books and discuss them with prisoners. Since 2005 there have been annual cooperations with the science year, an initiative by the Federal Ministry of Education and Research. Since 2019 the ilb cooperates with the Cluster of Excellence "Temporal Communities. Doing Literature in a Global Perspective" at FU Berlin.
