When conflicts exist between one school of thought and another, in some cases that is because one or both sides is incorrect. In other cases the problem is a communication failure: both sides are applying the same techniques in the same way, but describing them poorly (or at least differently). But I think there are other cases where the difference can be attributed to what I think of as different "recipes."
To be clear, I'm a lover of libraries, and for me there's no question that there are tremendously valuable resources there that are not available online (yet?). But it seemed like time to experiment with embracing an online approach to the assignment.
