How do industrial researchers get access to online journals?
But I suppose normal industrial jobs (e.g. software engineer in Amazon) don't grant online subscription to journal (like, access to a network IP with subscription, just like many university accounts).


Some industry research labs do subscribe to digital libraries, though in my experience, not as many as a university. For example, in the industry research lab where I'm currently spending my summer, I can access the ACM digital library, but not Elsevier journals.

To access papers that are not available by subscription, researchers in industry usually try one of the methods described in the answers to these questions:
