Deutsche Forschungsgemeinschaft (DFG)
The guidelines for making results from DFG-funded research available do not include an obligation, but a call for publication in open access:
- Contributions should either be published directly in quality-assured/professionally-recognised open access journals or on open access platforms or, in addition to being released by a publisher, be placed in discipline-specific or institutional electronic archives (repositories), if possible without delay.
- Researchers involved in DFG-funded projects should, as far as possible, firmly and permanently reserve a non-exclusive exploitation right in publishing agreements for the electronic publication of their research results for the purpose of royalty-free use.
- Publications must contain a reference to DFG funding.
