The Collected Poems of Sylvia Plath

"By the time of her death, on 11 February, 1963, Sylvia Plath had written a large bulk of poetry. To my knowledge, she never scrapped any of her poetic efforts. With one or two exceptions, she brought every piece she worked on to some final form acceptable to her, rejecting at most the odd verse, or a false head or a false tail. Her attitude to her verse was artisan-like: if she couldn't get a table out of the material, she was quite happy to get a chair, or even a toy. The end product for her was not so much a successful poem, as something that had temporarily exhausted her ingenuity. So this book contains not merely what verse she saved, but-after 1956-all she wrote." -Ted Hughes, from the Introduction.
