I was looking for some technical documentation in relation to development of a specific piece of software, using a Google search such as
"ACMESoft" "ACME_Rhino" filetype:pdf.
I found a PDF hosted on a European University's website which looked to be of interest; detailing some generic processes in relation to my search query.
I haven't read much of the PDF though, since I then went to see what other resources were available, so I browsed to a URL such as
https://fileserver.someuni.ac.at/files/cs/pdf/ instead of
https://fileserver.someuni.ac.at/files/cs/pdf/0815.pdf - and a full Apache webserver directory listing was presented to me.
It occurred to me that these PDFs were all people's thesis. I clicked a couple to check, and some were lengthy documents - Masters etc.
I didn't go to university, so I don't know whether these documents are supposed to be public-domain or not; but it would appear to me they shouldn't be.
Is there anything I should do in this situation?
