Frank Lentricchia on the Poem vs. the Corpus in analysis...

“To move, as I just have, from the single poem as closed, isolate, verbal system, a world unto itself, to the poem as microcosmic fragment of a poetic corpus, is to move, in a sense, not at all: for the corpus so conceived, as a synchronic whole, is likewise closed and isolate.” [Ariel and the Police 15]
