I am currently doing some research and a reference from 1982 has been cited in several more recent papers. The nature of the citations suggest this was a pivotal reference in the theory & practice related to my research so I am very keen to review it. The reference is a technical report - not a published article or book - that was issued by a university department. (The university is in the USA and not in my country). I have contacted the department in question but have received no reply. I have contacted authors that have cited the technical report - again no luck. I have exhausted online searches, including trying to track down the original authors online.
So I'm after any final suggestions (barring traveling to the university in person) as to how I could get a copy before I, reluctantly, move on without the reference.
