Poetry Technique and Forms
Resources

Rachel's Picks:
Just a few of my favorite places to find help and tips on poetry:

The Poetry Free-For-All Blurbs of Wisdom
An excellent resource for all things poetic – there are great threads here on everything you could want to know, covering critique, technique, meter, forms, and how to appropriately handle negative criticism (this last one applies mainly to participating in the workshop at PFFA, but it’s good knowledge for anyone who ever goes to any poetry workshop).  Many of the contributors at PFFA are accomplished writers and well-educated researchers.

Al Filreis’ Site at UPenn
A really incredible resource for help on technique, forms, subjects for poetry, etc.
He’s also the Faculty Director for the Writer’s House, which you can find on this site.  This site is HUGE – you could spend ages here.  In particular, this page is useful: Rhythm and meter in English poetry

Interlocking Poetry Forms
Very nice site, well designed and easy to follow.

Poetry at Ariadne’s Web
A site created and run by Ariadne Unst, which I’ve found to be helpful on many occasions.  Clear, informal explanation of forms with accessible examples.

And for everything else, Google it.
You can get anything there.
