http://www.jstor.org/Depending on how deep you want to get into any subject, JSTOR recently began to provide limited access to their journals. JSTOR is an academic journal aggregate that universities pay for access to. I used it a bunch in undergrad and have started using it again in the capacity they allow. You can save X amount (I can't remember offhand how many) articles to read over 3 weeks or so before you can reset the amount to a new set. You can't downloading anything, but it is a wonderful step in the right direction for making this sort of information easier to access.
