The number of scientific publications and journals is increasing constantly. Researchers have to stay current with ever more new scientific literature in their field and are also under increasing pressure to visibly publish their own findings in competition with their colleagues in the field. At the same time, it is become increasing difficult, particularly for non-scientists, to identify which journals are serious scientific publications. The large number of new online journals also includes “pseudo-journals” where the selection, editing and review of the submitted articles is often not transparent or does not meet scientific standards.France’s Académie des sciences, the German National Academy of Sciences Leopoldina, and the UK’s Royal Society are drawing attention to this situation and have developed joint guidelines for high-quality publications in scientific journals. These were presented to the EU Commissioner for Science and Innovation, Carolos Moedas, in Brussels.
