Reddit mentions of The Giant Book of Poetry: The Complete Audio Edition

There's the Giant Book of Poetry which is over 700 pages and basically spans all of written history (from years BC to poets born in the 1980's). There's bound to be something you like in there.

There's also The Vintage Book of Contemporary World Poetry (vintage here refers to the publisher, in case you were thinking "vintage" and "contemporary" were contradictory lol). This book has a wide variety of poets that might be lesser known since they aren't American, but still includes some well loved poets including Pablo Neruda and Seamus Heaney. This is a great one too.

I've recommended this a few times on here but there is also the Best American Poetry Series. It comes out every year. Basically, a prominent poet is chosen as the editor each year and they choose the best (totally subjective, but still) poems that were published in literary magazines that year. While it's limited to American poets, it provides a huge variety of poets both established and emerging. Also, it comes out every year, so that's pretty awesome too. The most recent one is Best American Poetry 2013 whish was edited by one of my favorite poets, Denise Duhamel. Totally recommend it. Good luck, hope this was helpful!

The Giant Book of Poetry has everything from 4000BC through Shakespeare up to contemporary stuff; it's a great starting point. And, unlike a lot of poetry anthologies, it's only $15.

Get a book of poetry and leave it within reach of the can. You never know when you'll need it, and nothing relaxes the bowels like some Coleridge or Yeats.

Probably look for anthologies, such as 101 Great American Poems, or the Giant Book of Poetry.
