Well... I am sure someone made good money out of that.
In Slovenia, a post-Yugoslavian country, the school library coordinated a textbook borrowing scheme, where they would own all the material and lend it to students each year. Parents would pay a small "subscription", so each year or two one subject would get new books.
That's how it worked in USSR in 80s. The school supplied the books and they were the ones that the previous grade used. If they got busted beyond all repair only then they'd be replaced with new.
