I am a student from a third-world country. How can I access the APS and other online journals? In my country most students dont have a .edu email address. Any idea where I can access such kind of valuable knowledge? Also, I have seen that most of the reasearch papers are locked behind a sub-wall? Any particular reason why? I really love to read new stuff. Unfortunately, I am not privileged to study in an american or a british college. I just came across this link on the PhysicsForums about free access: https://www.physicsforums.com/showthread.php?t=419118 But I am not able to access these journals? What should I do?
