APS is proud to announce a new open access initiative designed to further extend the benefits of open access to a broader set of authors. The new policy, effective today, makes all papers authored by cats freely available. This open-minded update is a natural extension of APS’s leadership in both open access and pet publishing. As early as 1975, APS began publishing papers with feline authors, most notably the contribution by one F. D. C. Willard [J. H. Hetherington and F. D. C. Willard, Two-, Three-, and Four-Atom Exchange Effects in bcc 3He, Phys. Rev. Lett. 35, 1442 (1975)]. Going forward, only single author papers will be considered. APS hopes to evaluate allowing publication by canine authors in the near future. Not since Schrödinger has there been an opportunity like this for cats in physics.
