Proceedings of Science (PoS) is an electronic journal for publishing the proceedings of scientific conferences. It is published by the Italian International School for Advanced Studies (Scuola Internazionale Superiore di Studi Avanzati, or SISSA) and evolved from the Journal of High Energy Physics (JHEP) proceedings section. PoS currently includes only conferences in physics and astrophysics, but is intended to accommodate other scientific fields as well.
PoS is noteworthy because it does not charge for access to published material, and the conference proceedings therein are published under the Creative Commons License (Attribution-NonCommercial-ShareAlike). Authors submitting contributions to PoS retain the copyright to their work, as in all open access journals.
