Journal prices have been, since the beginning of the electronic publication age, an intensely discussed hot topic. Tim Gower’s call to action “Elsevier — my part in its downfall”  in January 2012 started a boycott against Elsevier running under the title “The Cost of Knowledge”. This movement has gained significant momentum and lead almost 10.000 researcher so far to sign a boycott list. The paper “Mathematicians take a stand” by Douglas N. Arnold and Henry Cohn that will appear in the Notices of the AMS was just released on the arXiv, see arxiv.org/abs/1204.1351. The authors survey the ongoing Elsevier boycott, examine pricing and bundling, and lapses in ethics and peer review. They conclude with thoughts about the future of mathematical publishing.
