It seems like there is very little pirated content for schools (textbooks) in the piracy scene. Here in Germany, e-books are becoming normal in education.
So I ask you, especially the Germans among you, if you know of resources for pirated textbooks used in schools and if you are interested in such.
Such books as PDFs are actually useful, as you might imagine, since proprietary apps (several) are standard.
Library Genesis (www.libgen.is) is an extremely useful resource for textbooks. Not guaranteed that it’ll have what you’re looking for, and I don’t know much about it outside of the english language, but there’s a decent chance you’ll find what you need.
I’m a teacher and i always tell my students to definitely don’t ever go to LibGen where their textbook is likely available totally free and certainly don’t return your textbook and i absolutely won’t be using it myself either.
