Research output is not only research articles. To provide outlets for publishing other outputs than articles, Copernicus Publications, an innovative open access publisher based in Göttingen, Germany, currently publishes the journals Earth System Science Data and Geoscientific Model Development. The first journal is dedicated to the peer-reviewed publication of articles on original research data sets in the Earth System Sciences. The second journal is dedicated to publish the description, development and evaluation of numerical models of the Earth System and its components. Both journals apply an innovative interactive open access peer-review with public referee reports, public comments from the community prior to editor's decision, and public author's responses. The motivation is to make the whole research output from data, to models, to the scientific findings and novel interpretations freely accessible, to foster scientific discussion, to increase transparency in scientific quality assurance, and to give credit to all involved contributors.
