If you are interested in the Philosophy of Science, you need to know about the University of Pittsburgh's Philosophy of Science preprint archive. This makes available literally thousands of scholarly articles on all aspects of the philosophy of science, even before they are published in the journals. They have conference proceedings for recent conferences and all kinds of stuff. You don't have to be a subscriber to log in either. Most of the papers are downloadable in PDF format, so you can save them to your computer to read there and/or print them out.
