This is a trove of detail about poetic forms--hint: there are a whole lot more than iambic pentameter. Williams gives details and prodigious examples of dozens of forms of poetry, including forms whose names I can't even pronounce, such as "Englyn Penfyr" and "Awdyl Gywydd." Hint: don't look for them in your local library too much. This is a reference book for poets who are interested in the technics and the pyrotechnics of their craft. Williams adds a rather breezy history of Western literature and poetry. Read more of my reviews and poetry here: http://richardsubber.com/
If your goal is to read poetry (including Miller's) organized by forms, or if your goal is to try to write your own, is there a better resource than the man from Hoxie, [Lawrence County] Arkansas?
"In 1962, with writer Flannery O’Connor’s help, he got a job in Louisiana State University’s English Department. Four years later, he joined the faculty of Loyola University in New Orleans, Louisiana, where he founded and edited The New Orleans Review. In 1970, he returned to UA as a member of the English Department and the graduate program in creative writing."
