When Eliot died in 1965 he had no idea what had happened to this notebook, but it had in fact been sold to the Berg Collection in the New York Public Library in 1958. But no announcement was made until 1968. The contents of this extraordinary manuscript have never before been published in facsimile, and as Robert McCrum says in his foreword, the notebook is 'a treasure of double rarity: a document charting the turning-point in twentieth century literature, but also a window onto a lyrical catharsis that its author wished to remain mysterious'.
