In case you haven't found it yet, JSTOR, a digital library of academic journals, books, and primary sources, now has many scholarly writings available with a free account. Things from the past three years may be restricted, but it seems that most everything else is available. You may also be able to sign up through an academic library nearby or your own university and not have a time window limit. It is a great resource if you don't have a good library nearby (or just want to couch surf
.)
I was able to sign up for a free account and access the Virginia Magazine of History and Biography without leaving my chair. You can have up to three things on your "Shelf" at a time Each item must remain on your Shelf for 14 days, then it disappears unless you purchase a download. You can even save the citation information so that later, after you have returned the material, you find find it again easily (although figuring out how to use this feature was a challenge and the citation may not be in standard format.)
