After an intense period of behind-the-scenes effort, CERN’s open access, library, purchasing, and legal staff, along with the SCOAP global Steering Committee and Technical Working Group, secured with leading publishers the participation in principle of 12 HEP (full or partial) journals; developed a project governance structure; crafted a framework for performing calculations for subscription reduction and re-direction; and are putting into place a series of National Contact Persons (NCPs), who are responsible for securing participation from libraries, library consortia, research institutions, and funding agencies in their countries.
