In my country every engineering or math student had a copy of a translation of a book by the Russian authors Bronshtein and Semendyayev.

+1 for Bronstein. I had classmates in my physics program who brought their family bronstein (later my father who majored in German philology told me he had a Bronstein himself for when he tried to study civil engineering, but gave it away to a friend after switching majors, I would have loved to have a family Bronstein :-) )
