In Europe we just have scripts for each lecture. Professors may liberally take and modify content from books so you might sometimes wanna check out their sources in a library but you do not need books.
My favorite was when I took Calc 2 and the teacher just told us if we knew someone who took the course in the last 7 years ask if you can get theirs. The new version just deleted 4 chapters and didn’t even change the chapter numbers. It just went something like Chapter 1,2,3,4,5,6,7,8,13,14,15… brand new price tag though.

Here in the Netherlands we had some teacher who wrote a (small) book on “How to write professionally” and of course that book was mandatory.
