"The poem 'Sleeping on the Wing' I first saw in O'Hara's 1957 book Meditations in an Emergency, which I got in Spring 1959. Over the years, this particular one grew on me and eventually I began to see more and more in it--hence, the cursory annotations you see here, which led to a full-scale assault. Well, not exactly 'led,' because the annotations here are cumulative; some occurred even after I wrote out the poem on successive sheets and made more notes for almost every word."
