In the wake of Aaron Swartz's suicide after being hounded by Federal prosecutors, I wondered if people knew where to find peer-reviewed articles for free.
JSTOR and many other academic publishers often want 30 to 40 dollars an article. An article! You can see how this can quickly become untenable for someone on a budget. Heck, that's a lot for someone who even has some means (I wouldn't say I have means, but I do consider myself firmly middle-class.)
