Jones also founded "The Welsh Review" in 1939, which he edited until 1948; this journal was important for raising discussion of Welsh issues and for attracting submissions from such authors as T. S. Eliot and J. R. R. Tolkien, whose Breton lay, "The Lay of Aotrou and Itroun", he published in 1945. He continued to support Welsh literature by chairing both the Welsh Committee of the Arts Council of Great Britain and the first editorial board of "The Oxford Companion to the Literature of Wales". In 1977 he edited the "Oxford Book of Welsh Verse in English". He also published three sets of lectures on Anglo-Welsh literature: "The First Forty Years" (1957), "Being and Belonging" (1977), and "Babel and the Dragon's Tongue" (1981).
