In addition to going directly to articles, consider dropping an email or two to researchers working on those topics (perhaps once you've found an interesting article of theirs). Many are very willing to provide their overview of the area and point you to interesting resources. While there are times when you won't get a response (for example, before conference season or at the end of the semester), most are genuinely pleased to be contacted by people interested in the topics they care about.
So I'm all geared up and ready to go trawl through some academic journals so I can figure out how to tackle a problem or two, and I've realized I completely forgot how to go about it. Not going to a university with paid subscriptions to JSTOR, etc. doesn't help either. So where exactly does one go to access such journals? Is there a cheap way to do this? Thanks.
