During her lifetime Marianne Moore was that rarest of combinations, a genuine leader in the art of poetry, as well as a bona fide celebrity. She was an instantly recognisable symbol of Brooklyn, New York. However, because of Moore’s restless, seldom-ceasing, decade-spanning revision of her own poems, creating a ‘stable’ text of her work has posed editors a challenge ever since. ‘Omissions are not accidents,’ she wrote pointedly in that edition, but for some readers the absence of more than one hundred poems constituted a wilful neglect of her startlingly innovative, highly influential early work. Heather Cass White has prepared an edition of poems that, for the first time, presents the full range of Moore’s work in its published order, while honouring the complex textual lives of the poems.
