I bought this book back in 1977 for school. It is the best general reference I have ever seen for interpretation and analysis of the structure of poetry. Unfortunately, it has been out of print for many, many years. I still have my copy from thirty-nine years ago, never discarding it after a dozen times moving because it is that valuable. My husband loves it as well. If you can get a used copy from Amazon, snap it up. It is well worth the money.
