I was at university from 1989 to 1993, then tried to keep up with my field for a coupe of years more. When I lost interest about 2000, there still weren't any online resources that I could use, not even from the university library -- which didn't have any computers in any case, let alone access to online journals. Of course, my field wasn't technical -- comparative linguistics of the Tibeto-Burman languages -- but it was a fairly primitive era, too.
When I got interested in Krita around 2003, I didn't have any access to a university library anymore, but others in the project had, and they could usually give me a pdf of any article I needed, though sometimes I needed to approach the original authors.
