What are the ethics of citation? Don’t all poems enter into the cacophony and babble of “the great conversation,” or to mix metaphors, that river of text, of jetsam and flotsam we all swim in and against? Still, to take up a gentle anachronism, we might ask, who sits at the table, and what is the etiquette of the host? How do you turn to your citation-guests? What do you offer? Two recent books, very different in subject matter and affect, take up this question — as both are explicitly addressed to other work(s) of art, inviting them, as it were, to the table.
