The new German-language Open Journal Systems (OJS) information platform, OJS.de, provides general information on OJS and target-group-specific information on establishing and operating an open access journal with the help of OJS. The practical resources, for example the cooperation agreement for OJS hosting and the checklist for the first consultation with scientists interested in OJS, are aimed at facilitating and promoting the publishing of scholarly journals or journal articles in open access. The information platform OJS.de was developed within the framework of the DFG-funded project "Sustainable OJS infrastructure for the electronic publication of scholarly journals".
