While I have the blog open, let me throw in a quick two cents to support the Boycott Elsevier movement. As most working scientists know, Elsevier is a publishing company that controls many important journals, and uses their position to charge amazingly exorbitant prices to university libraries -- and then makes the published papers very hard to access for anyone not at one of the universities. In physics their journals include Nuclear Physics, Physics Letters, and other biggies. It's exactly the opposite of what should be the model, in which scientific papers are shared freely and openly. So now an official boycott has been organized, and is gaining steam -- if you're a working scientist, feel free to add your signature. Many bloggers have chimed in, e.g. Cosma Shalizi and Scott Aaronson. Almost all scientists want their papers to be widely accessible -- given all the readily available alternatives to Elsevier (including the new Physical Review X), all we need to do is self-organize a bit and we can make it happen.
