Collected Poems brings together the poetry Plath wrote from her youth until the end of her life, edited by Ted Hughes. It includes the contents of The Colossus and the later work that appeared in Ariel, along with many poems unpublished at her death. Arranged by date of writing, it lets readers follow her development from careful, formal early verse to the daring, concentrated voice of her final months. The volume received the Pulitzer Prize for Poetry in 1982. It is the standard place to read the full range of her poems.
