A fundamental part of science is dissemination. Previous research has analysed dissemination practices in few of the central publication outlets. In this chapter, we add into that research by analysing dissemination practices of CER in a range of 1523 journals and conference series that are (a) exclusively dedicated to CER, and (b) in outlets that publish CER together with other topics, such as general education, engineering or computer science. Our results show that a small and highly dedicated core of venues publishes a remarkable share of CER, that CER has a conference-oriented publication tendency, significant variations in citation rates, and differences in the diversity of topics within and between the dedicated and non-dedicated publication outlets. In all, our macro-level analysis makes a significant contribution into the research of dissemination in CER.
