Responsibility of the professor (Score 1)

As a teaching member of various ivory towers, I only require one book for all of my history classes. A little ten dollar history primer from the very short introduction series. The rest of the class material comes from lectures, powerpoint, journal articles and group discussion: you know, the things that make it a learning experience apart from just reading a textbook. Of course, if students want recommendations on reading material that they can use outside of class I am happy to provide that as well.
