The Stanford Encyclopedia of Philosophy offers excellent, up to date information on just about every topic within the field of Philosophy. My favorite part about this site is the fact that it is imminently searchable, and when you get your results, it will provide you with what you were looking for and also with related topics. To give you an example, if you search for beauty, you will get results on beauty specifically, but you will also get results related to 18th Century British Aesthetics, Aesthetic Judgement, Plato’s Aesthetics, Hegel’s Aesthetics, and many other related articles. If you want to research ideas, or where ideas came from, this is one of the best sources available online.
