SCOAP3 will start operations on January 1st, 2014. SCOAP3 is a partnership among libraries, funding agencies, and research centers. SCOAP3 works with publishers to make key journals in high energy physics open access. Partners of SCOAP3 pay into a central fund that is then used to pay the publishers for the costs involved in publishing, thereby allowing them to make their journals open access.
