I am facing a problem, the article seems a very important reference that everyone talking about the subjects is citing it. However, looking at these articles, they can't give a reference or link to the cited article. Even I use the volume number, article number to search on the net, I still can't find it.
For example, this article, only the second reference doesn't have a pdf link pointing to it. I think the author may be like me can't find the article, but sees others citing it in a very important position, so he also cites it. I can't exclude the possibility that the author reads a paper-based version.
When you search the citing article, many of them can't give a link to that paper, and I can't find it either. Should I cite it anyway? Because from the inspection, this paper seems an indispensable reference when talking about the subject. On the other hand, I can't find it (even on the official site) and I didn't read the abstract or even the title. I think this is not quite equal to the case where the article is behind the paywall, because behind the paywall you at least see the title and abstract.
