at the risk of sounding all buddhisty and all, I feel I ought to point again to Access to Insight. it provides n enormous amount of texts for Buddhist study, including a great deal of the Pali Canon in translation. texts, commentaries, even help with the Pali language itself, were you so scholarly minded. this is what the perfect world vision of the Internet would provide, back when we were dreaming about what the Internet could do. sensible navigation, visually clean and clear, it's simply a great repository of works. a companion site, Sutta Readings, provides readings. this is useful as much of this work originated orally, with reinforcing repetitions that you can find yourself skimming as you read. the frame of reference for both sites is Theravada Buddhism, but not exclusively.
