In 1968, three years after T. S. Eliot’s death, his drafts of “The Waste Land, ” long thought lost, were unearthed in the New York Public Library. First published in 1971, edited by Eliot’s widow, they revolutionized the understanding of the poem’s creation, by making apparent Ezra Pound’s outsized editorial role, including many ruthless cuts, and also the input of Eliot’s troubled first wife, Vivienne. These pages—some handwritten, some typewritten, with wordless loops and slashes scrawled across the text and brusque observations at the side—have become famous in their own right, and, for the hundredth anniversary of the poem’s publication, the edition has been reissued, with extra material. If you badly wish to know how much Eliot spent on breakfast at the Albemarle Hotel, Margate, on the north coast of Kent, in October, 1921, your craving can now be satisfied, because his hotel bills are shown in all their glory. Few Eliot fans will be able to resist.
