**UPDATE 1/2/12** *It is now possible to restrict the costofknowledge list by subject. So it has become easy to work out, for example, that (at the time of writing) 2632 people have left their names, of whom 613 are mathematicians.*

Many thanks to Tyler Neylon for designing a website where one can declare one’s unwillingness to work for Elsevier journals. Already, without any announcement apart from brief mentions quite some way into the comments on the last post, it has 31 signatures, many of them from France, where for various reasons they are particularly annoyed with Elsevier.

This post is primarily to give the site some visibility, which I’ll also do on Google+ (if you support the venture, then please spread the word). It is not necessarily to persuade you to sign. I well understand that we are all in different situations and signing is easier for some people than others. But one thing I would definitely say is that if you already have a private non-cooperation policy (as I myself have done for years) then you will have much more effect if you go public about it. As I said in my previous post, the more people who sign, the more morally and socially acceptable it becomes to sign too: a private protest is just a nuisance to other mathematicians, but larger and more public one may have a chance of achieving something. So I hope that each signature will beget several others, at least for a while.
