Under the URL https://key-concepts.sfb-affective-societies.de/, the glossary provides concise explanations of the concepts developed in the research work of the Collaborative Research Center and provides orientation on the theoretical framework of our research perspective. The glossary will be continuously updated and expanded and will make the SFB's key concepts permanently accessible. Key Concepts Online is realized with the Open Encyclopedia System, a development of CeDiS at Freie Universität Berlin. The SFB would like to thank Brigitte Grote of CeDiS for the excellent and timely technical implementation of our proposals. For questions regarding the content of the glossary, please contact Jan Slaby (jan.slaby@fu-berlin.de).
