kind, so that each should be an event." Typically, Eliot first published his poems individually in periodicals or in small books or pamphlets and then collected them in books. His first collection was Prufrock and Other Observations (1917). In 1920, he published more poems in Ara Vos Prec (London) and Poems: 1920 (New York). These had the same poems (in a different order) except that "Ode" in the British edition was replaced with "Hysteria" in the American edition. In 1925, he collected The Waste Land and the poems in Prufrock and Poems into one volume and added The Hollow Men to form Poems: 1909–1925. From then on, he updated this work as Collected Poems. Exceptions are Old Possum's Book of Practical Cats (1939), a collection of light verse; Poems Written in Early Youth, posthumously published in 1967 and consisting mainly of poems published between 1907 and 1910 in The Harvard Advocate, and Inventions of the March Hare: Poems 1909–1917, material Eliot never intended to have published, which appeared posthumously in 1997. During an interview in 1959, Eliot said of his nationality and its role in his work: "I'd say that my poetry has obviously more in common with my distinguished contemporaries in America than with anything written in my generation in England. That I'm sure of. ... It wouldn't be what it is, and I imagine it wouldn't be so good; putting it as modestly as I can, it wouldn't be what it is if I'd been born in England, and it wouldn't be what it is if I'd stayed in America. It's a combination of things. But in its sources, in its emotional springs, it comes from America." Cleo McNelly Kearns notes in her biography that Eliot was deeply influenced by Indic traditions, notably the Upanishads. From the Sanskrit ending of The Waste Land to the "What Krishna meant" section of Four Quartets shows how much Indic religions and more specifically Hinduism made up his philosophical basic for his thought process. It must also be acknowledged, as Chinmoy Guha showed in his book Where the Dreams Cross: T S Eliot and French Poetry (Macmillan, 2011) that he was deeply influenced by French poets from Baudelaire to Paul Valéry. He himself wrote in his 1940 essay on W.B. Yeats: "The kind of poetry that I needed to teach me the use of my own voice did not exist in English
