I've recently finished Mary Oliver's A Poetry Handbook and have begun writing my own poems (just for fun). I feel though that I may be limited by my having read little poetry. So, I'm searching for anthology recommendations to get some inspiration.

I'm not really looking for collections of "classics," just a large collection of poems generally considered to be "very good," and maybe leaning more towards contemporary (late 19th century onwards?). But I'd welcome recommendations outside of these guidelines too if anyone feels particularly strongly about some collection.
