A few standouts: "Nebuchadnezzar Solus" and "The Common Wisdom" will really stay with me. I like Nemerov's formalism, generally, although a lot of the poems here seem to serve their form, as opposed to the other way around.
The third section (as long as the first two sections combined) is mainly composed of a series of ars poetica and these really... didn't interest me. Not sure if it's a weakness of the poems themselves or if I'm just not a student anymore. Probably both!
