From CERN Press Release:
“After intense preparations and consensus building, CERN1 has today confirmed that the SCOAP3 Open Access publishing initiative will start on 1 January 2014. With the support of partners in 24 countries2, a vast fraction of scientific articles in the field of High-Energy Physics will become Open Access at no cost for any author: everyone will be able to read them; authors will retain copyright; and generous licenses will enable wide re-use of this information.”
