Following the publication of his Webster, scholars turned to him for editorial advice: he helped in the preparation of Hayward's Nonesuch "Donne" (1929), Housman's "More Poems" (1936), Theodore Redpath's "Songs and Sonets of John Donne" (1956), and Ingram and Redpath's "Shakespeare's Sonnets" (1964). He also performed an editorial and advisory role for Christopher Sandford at the Golden Cockerel Press, where he introduced Victor Scholderer's New Hellenic typeface (1937). A number of his verse translations from Greek and Latin, with engravings by John Buckland Wright, were published in collectors' editions by the Golden Cockerel Press and Folio Society. In the middle years of his career he was in demand as an invitation lecturer, giving seven BBC wireless talks in 1930, on Dorothy Osborne and on the Victorian Poets, delivering the 1933 Warton Lecture on English Poetry to the British Academy, lecturing at the Royal Institution on Classicism and Romanticism (1935) and at the Royal Society of Literature on travel writing (1937), and, as part of a British Council drive to counter Soviet propaganda, lecturing in German on European literature to packed halls at the British Information Centre in West Berlin in October 1948 during the Berlin Blockade.
