PhySH, APS’s physics classification scheme, is now publicly available under a Creative Commons CC0 license. Created to provide a fully open, high-quality classification scheme for the entire physics community, PhySH groups concepts into a flexible hierarchy that organizes content by topics.

Seven years ago, Physical Review X (PRX) was launched by APS as its first open-access journal to offer high quality coverage of all areas of pure, applied, and interdisciplinary physics.
