Making research results accessible on the internet free of charge

Research results can be made accessible free of charge on the internet either by posting them in discipline-specific or institutional electronic archives (OA repositories) in addition to publication by a publishing house, or by publishing them directly in OA media that are referenced or that apply the quality assurance mechanisms recognised in a subject area. In the case of a direct open access publication, licences must be used to indicate which rights of use the publication involves.
