Marjorie Perloff offers 'Differentials' with her usual erudition, humor, and interdisciplinary insight. These essays, written between 1999 and 2004, address performance poetry, concrete poetry, multimedia poetry, constricted writing, and how teachers might help their students make sense of it all.



Perloff's prodigious knowledge of twentieth century artistic movements allows her to relate the work of Ezra Pound to Marcel Duchamp, to explain "differential poetry" that varies according to the medium of presentation, to compare the performance poetry of Laurie Anderson, Joan Retallack and Caroline Bergvall, and to elaborate on distinctions between Kenneth Goldsmith's rule-generated writing and Ronald Johnson's verbivocovisuals.



And how to teach 'experimental' poetry? Take nothing for granted. Insist on close readings. And a close reading must account for all the elements in a given text, not just the ones that support a particular interpretation, she reminds us.
