If you really want to read a paper, it’s often easiest to e-mail one of the authors and ask for a copy. I published a fair few papers in my time, and shared many of them like this many times without any issues.

The only issue might be that after a few years, it’s possible that none of the authors can be reached via the addresses on the paper anymore, so you might have to go through their university (I’ve never tried this, so ymmv).
