It took me four months to the day, but I plowed through the 700 pages of William Wordsworth's poetry like a plowhorse. This was my first time through most of Wordsworth's work, having read "Lyrical Ballads" (which he wrote with Samuel Taylor Coleridge) a couple of years ago, and I'm so glad I devoted my spring and summer to further exploring the 19th-century poet. The true standout of his work is the autobiographical (and very long) "The Prelude." I couldn't have said it better than James Mustich in his "1,000 Books To Read Before You Die," which led me to visit Wordsworth: "In The Prelude’s thousands of pentameters, Wordsworth charts the fears and fabrications, the habits and the intuitions, the shaping processes and private emanations of the self, in a way that no seer had previously envisioned; in his pages the human imagination comes to life as a natural resource worth the work and wonder of cultivation."

I should add that the notes in this Modern Library edition, edited by Mark Van Doren, are excellent and illuminate Wordsworth's now-obscure references. This is perhaps the best volume of Wordsworth to start with.

Wordsworth is an excellent poet that's not in dispute but a lot of the poems are not to my particular preferences. A lot of the poems are very long and boring but there is definitely several classics.
