Yet, while the poem is obscure, critics have identified several sources that inspired its creation and which have helped determine its meaning. Many see the poem as a reflection of Eliot's disillusionment with the moral decay of post—World War I Europe. In the work, this sense of disillusionment manifests itself symbolically through a type of Holy Grail legend. Eliot cited two books from which he drew to create the poem's symbolism: Jessie L. Weston's From Ritual to Romance (1920) and Sir James G. Frazer's The Golden Bough: A Study in Magic and Religion (1890). The 1922 version of The Waste Land was also significantly influenced by Eliot's first wife Vivien and by his friend Ezra Pound, who helped Eliot edit the original 800-line draft down to the published 433 lines. While The Waste Land is widely available today, perhaps one of the most valuable editions for students is the Norton Critical Edition, which was published by W. W. Norton in 2000. In addition to the poem, this edition also includes annotated notes from editors and from Eliot, a publication history, a chronology, a selected bibliography, and a collection of reprinted reviews from the 1920s to the end of the twentieth century.
