In 1950 a friend presented the young Welsh poet T.H. Jones with a hand-made, leather-bound octavo notebook, the ‘Black Book’ into which he subsequently copied every completed poem he wished to preserve until shortly before his untimely death in 1965 at the age of forty-three. The Collected Poems of T. Harri Jones (1977) included a brief selection of unpublished poems from this notebook, as well as the poems from Jones’s four published volumes. Now, some thirty years later, we have a collection of all the poems from the notebook, as well as those from earlier preserved manuscripts, some only recently located. It also includes a handful of poems completed between the filling of the Black Book in 1964 and the poet’s death, and some additional poems that the poet considered ‘too “occasional” for preservation’, thus making it the first complete gathering of his large and impressive poetic oeuvre. The editors include a biographical introduction and extensive notes dating the poems, identifying first publications, and explaining literary and personal references.
