Pratt: Letters, the last instalment of the Collected Works series… the collection that the editors present is vast – and wholly indispensable for scholars in the field and those with an interest in Pratt’s poetry … Popham and Pitt’s detailed effort is undeniable, serving any interest reader beyond expectation … This resource is one for the shelves of any researcher in the field, and will no doubt be cited regularly.
