At least "Python for Data Analysis" is a pirate copy. Wonder how many others are too. But as long as you make money from affiliate links you don't care, right?
I don't want to host pirated content, so if it is I will remove it.
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.
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.
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.
