When I studied in South America, our professors were very open about it. None of us could have afforded textbooks anyway (by a large margin), so usually, only the professors would have the original textbook and worked with the small photocopy business located on campus to scan the book once and print as many copies as the students needed. The copies were bundled properly and all. Same with any software, files or operating system.

Mostly fiction. Studying or working full time means I read to escape, unless it's a textbook. There are many non-fiction books I'd like to try, but I never have the energy.
