Access to the Multi-Science Publishing Journals (Knowledge Exchange Licence) is start-up financed by Deutsche Forschungsgemeinschaft DFG (German Research Foundation) and is organized by German National Library of Science and Technology (TIB) Hannover.
After Multi-Science has stopped publishing in 2016 content is currently not available. The TIB Hannover is looking for a way to bring back the content the DFG has once paid for.
