that's a shame considering how flawed the peer review process is in Western academia. Were you able to use non-English peer reviewed journals? Many of the Russian ones are quite good.

I think it also depends on the field you are in. In science fields, people mostly fixate on current research. In other fields like history and theology, even hundred-year old journal articles can still be quite relevant. So in the STEM subjects the online material seems to dominate whereas in the humanities, a lot of the useful material is still found offline.
