Global life systems Book

This book is chock full of great information about poetry. It talks about poetic devices, different forms and styles of poetry, and different sorts of feet, and all sorts of useful and relevant information. The problem is, this book is not organized at all, and the explanations are all given in the forms of the poems themselves, which is very clever but makes it hard to understand. It's hard to know what parts of a specific poem are real rules and which are arbitrary. I found it frustrating when I was looking for something in particular because everything is difficult to find and in seemingly random order.
