To help meet this need, as well as expand the current content of Science so as to include even more diverse topics in science, engineering, technology, mathematics, and the social sciences, AAAS will be launching, in early 2015, a digital-only journal, Science Advances. Like Science, this new publication is designed to encourage transformative research and serve a wide readership. Our view at AAAS is that science is becoming more integrated and interdisciplinary, and therefore we prefer to provide one additional broad journal rather than a number of disciplinary titles, each with more limited scope, that would all have to be searched to find the papers of most interest. Also like Science, this new journal will aim for rapid publication. To contain costs for Science Advances, the journal will publish original research and review articles only, although select papers in Science Advances may be highlighted in Science through News and Commentary coverage.
To ensure the greatest accessibility for authors and readers, the new journal will be open access, with publication funded through author processing charges. With this publishing model, the number of papers that can be published is limited only by the quality of submissions. With digital-only publication, all papers will be posted as soon as they are ready for publication.
Nature already launched its own version - Nature Communications. Also, from Nature’s website, you can get some idea about the costs of making your papers open access or CC-BY.
