Peter Suber's Purview
One source that crops up more than most in these blog posts is that of Open Access News. This is simply the best place to go for information about open access activity. But its creator, Peter Suber, does more than offer a handy one-stop shop for such news: he performs the equally important task of pulling together disparate pieces of information, to create a whole larger than the parts.
A case in point is this wonderful "raft" of blogger comments on the imminent FUD campaign against open access, where Peter kindly includes my own witterings on the subject. Reading this bundle of blog rage warms the cockles of my heart; it also offers a handy reminder of the moral and intellectual energy ranged against the retrograde forces of the anti-open access bloc.
