Also the PDF has a link to a notorious ebook pirate platform on every page. If you really believe content on college pages is legal, you must be very naive. I've never seen a naive webmaster that uses domain privacy though.
What surprised me is that the owner of the Canisius page appears to be teaching staff rather than a student. The other books hosted there seem to be legitimately freely available, however, so I'm guessing that was also a naive mistake.
I'm not very familiar with ebook pirating platforms. So the link didn't seem suspicious to me.
Anyway, the book was removed. Thanks again for pointing it out.
