This New Casebook follows the astonishingly rapid growth of a literary reputation, culminating in the winning of the Nobel Prize for Literature in 1995. Using reviews as well as extended academic essays, it presents a debate to which the poet himself has made influential critical contributions, and which changes direction with the publication of each new volume of poems. In particular, the Casebook shows how a wide range of contemporary theoretical approaches have been brought into play as Heaney has become increasingly central for readers, students, and critics of contemporary poetry.
