I know of a site which offers about 20,000,000 published articles for free. I don't know if it's copyrighted material, so I won't post it until a moderator says it's ok, as I believe linking that site would be a breach of the terms of service. A way to go around it is to PM me, if that's ok with the mods.
I don't know what site you have in mind, but
arxiv is the place to go for physics/computing/math/statistics articles. They are all open access. Many scientists put preprints of their articles on arxiv at the same time as they submit them to a journal (I have one). So the work is bang up to date. This is a great step forward in the democratization of science. Your reading is not limited by the need to have access to expensive journals. For those who are not hard-core professionals, there are nice sections on "Education and physics", "Popular physics" and "History of physics".
