So this link is interesting for a different reason: look at the references at the end of the paper. It's awesome that the references include URLs. IMHO, old papers should all be updated to include such hyperlinks.

I'm pleased that the references to other ACM papers do work.

But try to click on this one:

Bainbridge, L. 1983. Ironies of automation. Automatica 19(6): 775-779;

https://pdfs.semanticscholar.org/0713/bb9d9b138e4e0a15406006...

Fail! No way to read the paper without paying or pirating by using scihub (and even if you do get the .pdf via scihub, its references are not hyperlinks). This does not help humanity, it makes us look like morons. FFS, even the music industry was able to figure this out.
