Big Open-access deal for particle physics

The entire field of particle physics is set to switch to open-access publishing, a milestone in the push to make research results freely available to readers.

Particle physics is already a paragon of openness, with most papers posted on the preprint server arXiv. But peer-reviewed versions are still published in subscription journals, and publishers and research consortia at facilities such as the Large Hadron Collider (LHC) have previously had to strike piecemeal deals to free up a few hundred articles.
