I haven’t been mentioning it all the time, but the philosophy papers blog has been featuring several new reviews from Notre Dame Philosophical Reviews. This is already one of the best sources for free philosophy on the internet, and these days seems to updated even more frequently than the Stanford Encyclopaedia. Hopefully in a few years there will be many sources of free philosophy, and in a way the 600 or so personal websites that contain free papers (linked in the sidebar of the philosophy papers blog) should count as extra sources. But for now NDPR and Stanford Encyclopaedia are the best high volume sources of philosophy, with Philosopher’s Imprint also notable if you want a more upmarket publication.
