The Living Handbook of Science Communication and Science Studies is to present relevant concepts, topics, theories, and results related to the development of the science system and to make them accessible to different audiences. In this way, knowledge produced across the boundaries of science communication research, science studies, and cultural studies will be embedded in public discourse to a much greater extent than before. The Living Handbook is the centerpiece of the RRC’s transfer strategy. Its main purpose is to make explicit the wealth of tacit knowledge about science communication and the science system. The Living Handbook functions like an open-access encyclopedia, taking advantage of linking practices to provide clear-cut answers on how science is working. It is intended to become the central information platform for relevant questions about the science system for science policy makers, science journalists, science communicators, and students, as well as for the interested public. In contrast to a traditional handbook, each article conveys a clearly defined topic, either in written form or with multimedia support, aimed at the general public or addressing the interdisciplinary community with in-depth peer-reviewed articles (1 – 5 pages).
