I’m a bit late to the party on this one, but I wanted to note a very exciting service that David Bourget and David Chalmers have set up, “PhilPapers”:http://philpapers.org/. Here is how the site describes itself.

bq. PhilPapers is a comprehensive directory of online philosophy articles and books by academic philosophers. We monitor journals in many areas of philosophy, as well as archives and personal pages.

At first glance, the page seems to do everything I wanted an online philosophy archive and index to do. The only downside is that I have so much reading to do now!
