Oh right, I think a big difference is that in American courses it seems that there is one course textbook, and the assignments are taken from that. Our courses weren't designed around a textbook. For us, assignments (both problem sheets and essay questions) were written by our tutors. They came with a reading list that would include a selection of relevant articles, books, and textbooks, but there was no single one that you had to use.
