Since I started my life in Academia, I sometimes found that there are some seminal papers to which I cannot get any access.
Either they are very old, and the journal that published them charges for it, or they are simply not to be found anywhere in the internet. I have to admit I never went to look for the physical copy in the library, but I'm not sure they would have it either.
When I asked a labmate about a reference he had in his paper and I could not find, and that seemed to be ubiquitous in any other paper in the area, he mentioned me he had never read it, but that reviewers usually demand that you should put that seminal reference.
How do you try and solve this problem?
