Letter to William Galbraith
Having received a letter from William Galbraith dated 7 March with questions about The Lord of the Rings, Tolkien immediately writes a reply, but mislays it and does not send it until 13 April. He hopes that it may be possible to publish the index he had begun, as well as other things omitted from The Lord of the Rings for reasons of space and cost. All that now impedes the publication of The Silmarillion is his finding time to prepare it.
