answer:I probably use Jstor more than anything. I also use Infotrac a lot. The volume of material on both is massive, but you do need a login for both (I think). My school provides both services to me as long as I’m enrolled, so I’m good to go, but after that, I’m out of luck unless I want to pony up the cash for a login. I have also found the outside references and sources on many wikipedia pages to be incredibly useful.
