Here's a link to Paul Manata's excellent article titled 'Free Will, Moral Responsibility, and Reformed Theology: A Contemporary Introduction'. (link) Paul's main point, that Calvinism is determinism, is spot on. Paul recognizes and answers the movement being generated by those denying Calvinism is deterministic. I also think the article serves as a highly useful interface into the literature on free will/determinism.
I do, of course, disagree with a number of points in the article, but they are fairly minor except in the arguments against libertarian free will section.
