The history is straightforward, so is the literature, but heavy on the New England School (I had never HEARD of Maud Muller, though. I looked it up, it's Whittier (who has gone out of fashion now) and it contains the catchphrase "the saddest words of tongue or pen. . ." Always knew that, never knew where it came from. But now I know.
I would have to really use up a bunch of paper on the math, and there are some obsolete concepts, but again it seems fair.
