As of February 15, 2011, authors in most Physical Review journals have the option to pay an article-processing charge whereby their accepted manuscripts are made available barrier-free and open access. These manuscripts are published under the terms of the Creative Commons Attribution 3.0 License (CC-BY), the most permissive of the CC licenses, which permits authors and others to copy, distribute, transmit, and adapt the work, provided that proper credit is given. The article-processing charges have been set to cover all costs, thus providing a sustainable model. These charges will decrease the need for subscription revenue and will help to keep APS's subscription price-per-article among the lowest of any physics journals.
