Manuscripts shown here range from John Keats' drafts in his own hand, to poems written on toilet paper by Sylvia Pankhurst while confined in Holloway Prison, to early versions typed by Sylvia Plath on the reverse of Ted Hughes' own discarded work.

Themed chapters allow for fascinating new comparisons between diverse objects - William Blake's 'London' (1794) sits alongside Andrew Salkey's 'Jamaica' (1973) in discussions of place - revealing how each manuscript has shaped our understanding and practice of poetry today.

Experts from the British Library explain the process and provenance behind poems from the UK and Europe, North America, Asia and the Middle East, highlighting the secrets that published poems often conceal.
