J.H. Prynne (1936-2026) was Britain’s leading late Modernist poet. His austere yet playful poetry challenges our sense of the world, not by any direct address to the reader but by showing everything in a different light, enacting slips and changes of meaning through shifting language. Not since the late work of Ezra Pound and the Maximus series of Charles Olson had the possibilities of poetry been so fundamentally questioned and extended as they were in the life work of J.H. Prynne. When his  Poems  was first published in 1999, it was immediately acclaimed as a landmark in modern poetry. Four further collections were added to the second edition of  Poems  in 2005, followed by a further seven along with a group of uncollected poems to the third edition of  Poems  (2015). The decade since  Poems  (2015) was the most productive period of Prynne's life, with over thirty limited editions published between 2017 and 2024. To have added these to a fourth edition of  Poems  would have doubled the size of that volume.  Poems 2016–2024  is therefore a separate, supplementary edition of his later work, including, except for minor corrections, the mostly unchanged contents of 36 texts written since  Poems  (2015), from  Each to Each  (2017), written in 2016, to  Alembic Forest  (2024), including the corrected 2023 text of  At Raucous Purposeful  (2022). The 26  Impromptus  comprising  Memory Working , originally published in three separate editions in 2020 and 2021, appear here as a complete sequence. Prynne's most productive decade also saw the publication of three prose works,  Graft and Corruption: Shakespeare's Sonnet 15  (2015/2016),  Apophthegms  (2017) and  Whitman and Truth  (2022), along with editions of Prynne's correspondence with Charles Olson (2017) and Douglas Oliver (2022). His two-volume  Collected Prose  is forthcoming from Oxford University Press (New York).
