Jones's major illustrated books include wood engravings produced for editions of "The Book of Jonah", "The Chester Play of the Deluge", "Aesop's Fables" and "Gulliver's Travels" as well as for a Welsh translation of the Book of Ecclesiastes, "Llyfr y Pregethwr". He produced an important group of copperplate engravings for an edition of "The Rime of the Ancient Mariner". He also executed commissions for one-off engravings such as his illustration for T. S. Eliot's "The Cultivation of Christmas Trees". He professed great disappointment in the way that his illustrations for "Gulliver's Travels" had been subsequently hand-coloured by art students, and complained about the too-light reproduction of the wood engravings for "The Chester Play of The Deluge". Jones gave up engraving because of eye strain.
