If you are buying locally, Chaucers is a good bet for poetry.
Committed to Memory; 100 Best Poems to Memorize, John Hollander
This is a great choice if you'd like a poem that is, as Hollander says, "rhyming accentual-syllabic." Many are pre-20th century. The entirety of this collection is available online at: http://www.poets.org/viewmedia.php/prmMID/17111
Poetry (to read) Out Loud, Robert Alden Rubin
This is the selection I chose for the Adult Ed bookstore to order, so you will be able to get a hold of it easily. It has a great selection of stuff, from Chaucer to Gallagher. Many of the selections overlap with those in the national recitation contest anthology, with which I have been impressed, but which you can only buy used. Besides, this collection is very nicely produced and reasonably priced.
Poetry Out Loud National Recitation Contest: The Anthology
This is the anthology that made me fall in love with Poetry Out Loud. I was impressed early on by the fact that they had chosen so many challenging poems, ones with real emotional impact and rich themes. Good variety. This book can only be bought used, since it was never on sale to the public. All of the poems in this book and many many more can be found at http://www.poetryoutloud.org/poems/
An Invitation to Poetry, edited by Robert Pinsky
This is one of three anthologies edited by Pinsky as a part of the Favorite Poem Project. I include this one in particular because I own it and because it comes with a free CD, but all of them are excellent. Keep in mind that some of these poems are ones that are memorized by those who love them, and others are simply read out loud, so some of them will not be super easy to remember. Still, these are great collections and I am always delighted by which poems people pick as their favorites and the reasons they give for loving them. Good anthologies for getting in touch with the many ways in which poems matter.

Poems to Read: A New Favorite Poem Project Anthology
Good Poems, selected and introduced by Garrison Keillor
These poems are selected from the many that have been read during Keillor's daily radio show, The Writer's Almanac. It offers a good mixture of traditional and modern poetry. Many of the poems are likable and easy to listen to. The poems from the show are archived all the way back to 1995 here: http://writersalmanac.publicradio.org/archive.php.
Unfortunately, there seems to be no good way (as far as I can tell) to search this archive. Fortunately, each almanac is also available in an audio version read by Keillor himself.
Another Anthology by Keillor:
Good Poems for Hard Times
Poetry 180: A Turning Back to Poetry, selected and introduced by Billy Collins
These poems are a part of a project for getting poetry into high schools. If you like Collins' taste, you'll like this collection. Most of the poems are contemporary, easy to enjoy, and even witty. All of the poems in this collection are also available at http://www.loc.gov/poetry/180/p180-list.html
Also in this series:
180 More: Extraordinary Poems for Every Day
World Poetry: An Anthology of Verse from Antiquity to Our Time, edited by Katharine Washburn and John S. Major
I include this not as a resource for Poetry Out Loud, but as a resource for poetry lovers. You will always have more than enough poetry around by owning just this one book. Every time I open it, I find a wonderful surprise, often something I did not even know existed.
