When you say "they just wanted to make sure we had a copy" you mean - they made you buy it as a "requirement" (that there was no way around it), or they just told you and most of you bought?
And by "they" you meant the faculty (professors etc) or college administration or some other office office? Just curious about it. I am from India and there are no fixed text books here (at least the colleges I know about - central Govt. funded). There are syllabi and you are free to study the course with anything you want - books, or no books. My college library solved textbook problem for almost 40% students and rest were solved by hands-me-downs from seniors, 2nd hand book stores (some of them have very capable xerox machines too), and then there's "online".
