I like to read old scientific papers. They give me a broader perspective on how things became as they are today. So when I came across this paper from 1977 in the reference list of a more recent paper, I knew I had to read it. Unfortunately, even with my university-provided access to most journals and most certainly to a journal like Nature, the evil overlords at Nature Publishing Group do not include papers as old as from 1977 in our site license. So I had to send a request to the library and wait a few days for someone to scan in a copy of the paper and email it to me, a relatively minor inconvenience.
In the mean time, I read the abstract, all that was available at the time. I noticed the affiliation of one of the authors: Rutgers, my undergraduate alma mater and current graduate school! Awesome, I'm all for school spirit! Except, the affiliation didn't actually say "Rutgers", it said "Butgers". A humorous typo... or something more sinister?
