She's at the top of my contemporary list. For a compendium of mostly terrific modern poems (short)- poems, not book) try Garrison Keillor's GOOD POEMS and the follow-up; GOOD POEMS FOR HARD TIMES. They are all there to be sampled; Donald Hall, Jane Kenyon, Billy Collins (ANOTHER REASON I DON'T KEEP A GUN IN THE HOUSE), my local poet, Edna St. Vincent Millay, Marge Piercy (ONE REASON I LIKE OPERA), Sheenagh Pugh, Maxine Kumin, Elizabeth Bishop, etc.
