I didn't really use any texts on poetic structure etc, as i knew what i wanted to do (structurally) from the get go.
I'd just go to your local library and type 'poetry' into their database. I definitely saw some at my local library (Warringah) when i was looking for Australian poetry. Theres heaps of 'How to write Poetry' and 'Enjoying and Appreciating Poetry' books out there
