PS3569.L3, David R. Slavitt's sixtieth book, is a collection of poems, translations, imitations, parodies, jeux de mots, and jeux d'esprit--work that ranges from grief-stricken brooding to exuberant clowning around. The odd title, for instance, is nothing more or less than the author's Library of Congress identification, which he adopts now that it has adopted him. Few contemporary poets display his range of sensibility and response to the various occasions of chaotic existence in our time, and Slavitt offers us his reactions to those stresses and cultural shocks that have not so much engaged his attention as ambushed it. He writes poetry that ascends to Pindar and Meleager, or descends some traditional prosodic scale even to the point where it risks gibberish--or basks in it--and he makes no apology for this.
