In this commentary, I will explore what I term the “iterative turn” in contemporary poetry. I take iteration to encompass a range of poetic practices, including repetition, sampling, performance, versioning, plagiarism, copying, translation, and reiterations across multiple media. I will focus here especially on how iterative poetry engages forms of political, economic, linguistic authority and their intertwinement with questions of media. The iterative turn in poetry can be understood not just as a shift in rhetorical form but also as an ethical and political response to the crisis in authority engendered by the rise of new technologies of reproduction and the increasing pace of globalization since the late 1980s. In the posts that follow, I will map out just a few of the many forms that this response takes under four broad headings: revolution, copyright, translation, and the book.
