You can publish a poem you think is a very important poem, and you don't hear a word from anyone. [...] You can publish a book of poetry by dropping it off a cliff and waiting to hear an echo. Quite often, you'll never hear a thing. So doing that, using older work, puts it in a context, and that sort of forces the reader to realize what its importance is-if it has any. Everything needs a context. You're not going to recognize a poet unless you have a context.
