This is the WORST textbook I have ever read, from its simple- and literal- minded deconstructions of great poems soiled by the dim illuminations of them, to its muddled explanations of prosody and poetics. There are far better books out there for the aspiring poet. Try "Writing Poetry" by Barbara Drake; "The Art of Poetry Writing" and "The Poet's Dictionary" by William Packard; "The Book of Forms" by Lewis Turco; "Thirteen Ways Of Looking For A Poem" by Wendy Bishop; and before all these others you must read "Letters To A Young Poet" by Rilke (translated by Herter Norton).
