I do not know of books. I have read tons of poetry here and follow a lot of poets. I have also watch videos of poets reading aloud and have attended one open mic even recently. My source has been pretty much that and what I have shared in my writing, trial and error, expressing feelings in the way they feel, taste, how they sound or how attractive or unattractive they feel to the eye. I also noticed there are some events in the local libraries, but have not gone to any yet. Hope this helps!
