The American Physical Society (APS), and CERN have agreed that all CERN-authored articles published in the APS journal collection are to be Open Access. CERN Director General Rolf Heuer called the agreement “A very important step towards global Open Access for a global discipline”. Thanks to agreement, articles will be available free of charge for everyone to read while copyright will remain with the authors and permissive Creative Commons CC-BY licences will allow re-use of the information.
