A great resource for philosophy

You may be sick of Thomas Kuhn by now, but I'm posting this url to let you know about the resource itself. The Stanford Encyclopedia of Philosophy has been quite helpful to me as a place to find quick summaries and extended reviews. It is difficult to remember all the philosophers, all the schools of philosophy, and all the various iterations of their views (cf. Wittgenstein, for example!) over their careers. This keeps me on track.
I also use the Encyclopedia of Philosophy, but that is on paper; this gives quicker, public access to all.
